BMW N20 Engine Repair

2013 BMW X3 with the popular, but troublesome BMW N20 engine.

Well maintained BMW X3 with BMW N20 Engine

Received this well maintained BMW X3 with a no start condition.  We were told, it was diagnosed at a Toronto dealership as “may” need a timing chain, and they opted to replace the timing chain tensioner assembly.

We tried to start it after being towed in, we did not succeed, the  car did not start. Got the owner permission to remove the valve cover, and oh boy the poor thing lost 80% of it’s timing chain guide. Therefore the timing chain jumped timing naturally, the computer was seeing the timing way out of specified position, and did not allow the engine to fire up. It cranked but did not start.

BMW N20 Engine Timing Chain Failure

Unfortunately we had to confirm a total timing chain failure. Honestly I’m not surprised for one moment as the car odometer had 229860 kms  in it, it’s lasted much longer than average.

BMW’s N20 Engine Common Problem

When all said and done, she run like a charm albeit had a low boost fault. Its BMW’s N20 engine common problem. After some further testing we found a turbocharger error.  The turbocharger wastegate was severely worn out.

The vehicle owner wanted this car to drive for a few more years, so we got a good quality used turbocharger to keep the costs down.

BMW N20 Engine’s Turbo Charger Replacement

We replaced the turbocharger at the same time updated the pressure feed line with the newer revised version, to ensure proper operation and turbo longevity.

We reset the adaptations and than road tested it multiple times. She is back in business and runs really well, “purring like a kitten”.

BMW 535 GT Repair | BMW 535 GT Maintenance

BMW repair many occasions requires an inside knowledge and decades of experience. Knowing what are the weak spots  of the BMW, comes whit knowledge and experience, hence we can prevent an expensive breakdown in the near future.

BMW 535-GT Front Propeller Shaft Failure

Here is a perfect example of a 535-GT front propeller shaft failure which is a typical issue on most BMW with accumulated kilometers on it.

This particular vehicle is maintained by its owner, we only see this vehicle when it’s broken. In this case not performing a preventative maintenance, cost almost an engine replacement, as the seized propeller shaft finally let go and punched a gigantic hole into the oil pan.

When We Service BMW 535 We Remove This Shafts

When we service BMW 535s we remove this shafts on the regular basis to check the U joint condition. In fact we even have replacement universal joint in house to repair this shafts as some of them cost some silly money from the manufacturer.

On this BMW we had a hard time to source a proper exact replacement oil pan and ditto for the front propeller shaft.

The owner got lucky, he managed to shut the engine down in a hurry, which saved his N55 engine. He said when the shaft broke he killed the engine instantly.

Either way we would not know if there is or has been any internal engine damage to the crankshaft or the bottom end bearings.

We had to come up with some clever solutions to test the engine, to be able to confirm the engine did survive the ordeal. Therefore we cleaned the broken oil pan with a de-greaser.  Let it dry and remove any oily residue, applied windshield glue to the open area around the hole and glued a heavy plastic sheet over on it, and let it cure overnight .

BMW N55  Engine Repair

Next day we removed the oil filter and filled up the channel with fresh motor oil quickly. When the engine had proper amount of oil in, we started her up instantly.

The engine run properly without any noise or sign of excessive wear. At this point we knew we can proceed with the proper repair and resurrect this vehicle to it’s former glory.

BMW N55 Engine Connecting Rod Bearings Replacement

Needless to say we will remove and replace the bottom end connecting rod bearings with new performance bearings,  just in case. Additionally the new performance bearings are superior design made with improved materials compared to the genuine bearings design.

It just makes perfect sense to replace them while we have the bottom end open. It’s a simple procedure at this occasion.

BMW Hybrid Repair – Hybrid Maintenance

In case you are wondering, do we repair and maintain BMW hybrids? The simple answer is absolutely yes.

BMW i3s with REX and a BMW i8

Personally I’m a big fan of hybrids as they provide a quick and very efficient transportation, in most cases without the inconvenience of range anxiety. Actually I’m driving (when I’m not riding my bicycle) a hybrid BMW for 7 years plus. Therefore I have first hand experience about BMW hybrids.

I own and drive a BMW i3s with REX and a BMW i8. I love both cars, but they’re built for 2 different purpose.

The BMW i3 is a city car, quick agile and traditionally rear wheel drive, hence you still have the BMW driving dynamics with the weight all at the bottom of the car. It’s like a little go kart if you will.

The BMW i8 is a purpose built performance hybrid to give you an astonishing light agile performance hybrid with the gas mileage of a Prius.

BMW Hybrid Repair | Software Update

We repaired few BMW i8 early 2014’s versions recently. As they accumulate the kilometers over the years, they require some maintenance and repairs. There can be some pattern problems, like the thin aluminum water pipe cracked beside the battery pack, where the owner was quoted some astronomical repair cost elsewhere.

BMW Hybrid Replacement Parts

The replacement parts were back ordered for months, therefore we decided to repair the defective component, instead of replacing it with a new one. We got the pipe repaired, weld and reinforced at a very reasonable cost. More like into the hundreds versus the thousands as it was quoted prior to us.

We also had an A/C compressor replaced on a BMW i8 recently due to noisy compressor. That particular i8 had the entire system flushed out and cleaned and new A/C condenser with dryer installed to ensure reliability for many years to come.

The pictures are from the i8 ac compressor and condenser replacement. The dark stuff that leaking out is the metal soup from the worn/ broken compressor assembly.

Did you know the BMW i3 and the BMW i8 both use the electronically operated and controlled air conditioning system to aid in the temperature management of the lithium ion battery pack? For that reason the the air conditioning system should be serviced every 3 to 4 years to ensure there is plenty of refrigerant within the system as it carries the lubricant within the refrigerant. It’s absolutely detrimental to have it serviced or it will cause a premature compressor failure due to lack of lubrication within the closed circuit.

BMW Hybrid Software Update

We look after other BMW hybrids as well like a recent E machine replacement on a 2018 530E which was unfortunately out of warranty due to driven distance. In this case we used the factory BMW ISTA diagnostic equipment and software for proper diagnostics with timely software update, re-flash if required, as per the manufacturers recommendations for the best possible results.

Environmentally Friendly Brake Pads

For BMW, Mercedes, Porsche and Mini.

Today we live in sensitive times, environmentally sensitive times.  Therefore we have numerous areas of the modern car and its components gone through multiple environmental revisions.

Car Tires and Brake Pads Are Going Through a Complete Change.

Two major changes come to mind: tires and brake pads are going through a complete change for a more environmentally friendly revisions. The framework for the copper and heavy metal free (more environmentally friendly) brake pads initiative has been laid down many years ago. In particular 2021 January was an important deadline for the brake pads’ friction material revisions.

Read the related document  here. Your web browser going to open the document in a new tab. You need to close that tab to return to this page.

Please note, this is a voluntary agreement by all the major manufacturers but they all signed up and agreed to a binding process initiated by the state of California and Washington. Lately I started monitoring the brake pads environmentally friendly initiative by each respective manufacturer.

We do install a lot of brakes and have been interested in how manufacturers of cars and or the aftermarket brands take charge in this important matter. I mentioned at above,  originally it started in California and Washington state, but has been more or less voluntary in Canada.

Aftermarket Break Parts for BMW, Mercedes, Porsche and Mini.

To my surprise the aftermarket break parts manufacturers has been taking the lead so far.  We’ll see how it goes later, as I collect more data and keep an eye on the progress.

Please check the next photos out:  1st picture is BMW brake pad with a leaf symbol on. On the second photo is Textar brake pad from Germany, it has 3 leaf symbols on. The 3 is a Brembo Italian brake pad with 2 leaf symbol on. The 4-th brake pad is for Mercedes Benz with only a single leaf symbol on.

Environmentally Friendly Tire Technology – ECO Friendly Green Tires

Additionally the tire manufacturers are also taking charge in making more environmentally friendly tires, by using a blend of raw materials from more natural derivatives like dandelions, by Continental Tire. Orange peel by Yokohama Tire, Guayule by Bridgestone tire, and walnut shell in Toyo tires.  It’s quite interesting as these companies are taking the lead to provide a more sustainable product for the better.

I compiled a few interesting links for you if you’re interested in the subject , please enjoy.

The another day we had a persistent tank ventilation system leak on a newly acquired 2011 BMW 3 series. First we had the vent test pump failed and the fault kept returning.  After pumping a lot of smoke into the system we found someone hammered on the tightening ring onto the fuel pump assembly.

Unfortunately there was a chunk of the pump housing missing so we had to replace the pump assembly with a new ring and secured it with the proper tool.

BMW X5 N55 Engine Repair

Today, one of our clients BMW with an N55 engine required a special repair. We had to fabricate a special tool to extract the seized, severely corroded fuel injector from the cylinder head.

In this case, the factory injector puller is not adequate to make the injectors budge from their hole. This is a common issue on BMW X5 trucks with the N55 engine. In this case I had to solve the issue by fabricating a custom puller to extract the fused injectors from the cylinder head, without the removal of the cylinder head assembly.

Needless to say we were successful to resolve the issue at hand, and we saved a lot of time and $$$$ for our client.

Custom Made BMW Injector Puller

On the photo is our custom made BMW injector puller, attached to a injector, next to a already extracted BMW’s injector.

BMW repair at home. Should you do it yourself?

The ultimate question is, should you attempt to repair your own BMW? BMW is particularly popular with the young owners modifying them actively.

With the help of YouTube, people think they can tackle literally anything on their beloved car. So why bother taking it to a professional mechanic, right?

Repair your BMW at home. Should you try?

We had recently two actually 3 BMW when their respective owners tried to repair, fix with terrible results.

Owner #1: Young gentleman replaced his BMW’s suspension with fashionable lowering kit. While doing so he decided to replace the corroded steel brake lines and the old flex-lines with braided “race” ready version.

The suspension replacement went relatively well, only the suspension angles and alignment was messed up.  But YouTube brake line replacement went absolutely terrible, in fact more like terrifying.

BMW Brake Calipers Mounted to the Wrong Side.

Routing it thru control arms and moving components deleting the flex lines permanently to top it off he managed to mount the rear calipers upside down so they will never bleed the air from the system.

BMW Brake calipers are mounted to the wrong side, upside down, so they will never allow to bleed off the air within the hydraulic system. Brake lines are criss crossing and dangling against the fuel filter on the same BMW.

The question is what will leak first fuel or brake fluid? Flexible brake hose cut off and remnants are left in the mounting secure bracket on the same BMW.

Click on the thumbnail to view bigger photo. Your browser will take you to a new page. Use your browser “back” button to return to this page.

I’m not here to judge anyone’s job or competence, except this car came in with non existent rear brakes, brake fluid was dripping constantly on the floor.  It begs the question:  Why would you endanger your life and the life of others getting into a repair which is way beyond your knowledge and or qualifications?!

Oil Change on a Late Model BMW at Home. Was it Worth it?

The second owner performed an oil change on his own late model BMW.  Doing the process he removed the top of the air box, while doing so he accidentally left the paper rag in the lower part of the air box.

After the restart the engine lost power.  He had it towed to us and we did all the regular system test and kept having low boost and no boost faults from the computer. Naturally we checked wastegate operation and every aspect of related components.  Finally we decided on to see the turbocharger impeller face, with our fiber optic camera system .

Long behold we found a paper rag being sucked in by the turbocharger blocking the impeller entirely. Than we had the job to trying to extract the wrapped up paper rag and try to not to damage the fragile turbocharger impeller in the process.

Suffice to say, we managed to do it, but while the rag has been extracted we still had some paper pieces stuck between the impeller and the casing of the same. Finally we managed to remove all the bits and pieces and all is well at the end.

Culprit found, our labor on oil change is $20.00*, to resolve this issue costed him $240.00. You do the math, was it worth?

BMW Turbocharger in Action

BMW Drive-train Malfunction Message on the Dashboard.

The 3rd owner had a drive-train malfunction message on his BMW dashboard when the vehicle was driven in a spirited manner.  Owner diagnosed it with his hand held OBD 2 scanner.  After the scanning, he decided to replace the low pressure pump, but the problem still reoccurred. Than he decided to replace the high pressure fuel pump as well.

Needless to say the problem still persisted and the amount of money he spent is ludicrous to say at least . All was really required is a proper factory level diagnostics to pin the problem down.  Which actually was only a faulty high pressure sensor, reporting wrong data to the engine computer.

While the owner was busy replacing the high pressure fuel pump, he managed to crack the fuel line to the pump,  therefore it had to be replaced to.  The repair took additional hours, and considerable effort, as it was the low pressure line feeding the high pressure pump, and pretty much wrapped around the engine.

Please note, on BMW, the high pressure pump’s fuel lines must be torqued to the manufacturers specifications or may cause a split flare or a fuel leak onto the hot exhaust system.

Clients try to repair their own BMW.

This is ultimately world wide problem, created by YouTube. Clients try to repair their own BMW without the necessary knowledge base. Doing so at the end they  risk their own life and the life of others, which is wrong in so many ways, is a understatement.

Would you allow someone to perform “brain surgery” without any qualifications, on yourself or your loved ones? You wouldn’t.  Right?

So why is that people think they can just go in tackle anything on their own without any training or knowledge and see how it will turn out to be only by watching YouTube? This is just wrong so many ways .

Any questions how may we help?

BMW Rear Defroster on Permanently

People are saying, the right tool for the right job. Its apply for BMW repair to.  Correct?!

Late Model 435 GC BMW’s Battery is Flat Dead

One of our customer ran into a problem. His late model 435 GC BMW’s battery is flat dead. The car has been towed in.

The owner said it goes totally dead in a very short period of time. The car’s battery was 6 years old, it saw better times. Winter is comming and a 6 years old battery is old, this one is shorted and toasted. We replaced it.

A 6 Years Old Battery is a Old Battery

With new battery quickly check for excessive current draw. Tony found 15 amps steady draw at all the time, locked or not. When the ignition key is pulled out, it should go to sleep. But not so this one. Apparently something is draining the battery.

Preliminary checks done, no immediate clue which module cause the problem. Which one is acting out from the 50 or so onboard? Which one is staying on and “cooking” the battery in the process?

Failed Module. Which one?

Here comes the right tool that I mentioned in the first sentence.   Here comes Flir out to see what the human eye cannot see, which is thermal image.

Proper Maintenance of European Cars

Maintenance is #1 to any machine.  Proper maintenance to modern cars is absolutely essential.

Essential Maintenance

Performing the essential maintenance with the right fluids designed for the vehicle is an absolute must.

Naturally we do have a plethora of pictures of vehicles where the wrong fluids were used or maintenance was performed late.   The damage is caused by it, could get really expensive to correct.

Here is a partially encrusted AMG engine with too late oil changes and wrong oil has been used to top up the oil level. It will have dire consequences in the long term.

Click on the thumbnail  to view bigger photo.

Engine Oils & Manufacturer’s Recommendations

Let me explain please: If you use an oil in your car other than that specifically recommended by the manufacturer you will cause major damage to very expensive components in your car’s engine.

Today’s engines are designed and engineered with a specific way hence their manufacturer engine  specific approvals, which may or may not similar to the oils being sold at retail stores.

The old viscosity and API approvals are long gone.  Most manufacturers are very strict in their own special (concoction) a special chemical composition which is by itself is literally a science.

All this effort is being put into the goal to reduce friction, pumping losses and minimize engine wear on today’s super efficient but fragile engines.

On a high performance, AMG engine, one improper oil change can result in thousands of dollars worth of damage.

The other picture is a Mini Cooper S with a major and massive cooling system failure.  Wrong fluid used to top the cooling system up, which caused a complete cooling system failure.  The entire cooling system needed to be repaired.  It took considerable effort to minimize the damage.  The water pipe and  water pump essentially removed.  All the hoses to be cleaned  and flushed multiple times.

Modern high tech European cars are designed with very vehicle specific lubricants. Fluids with an exact chemical composition are essential to have your fine car last and perform as intended.

What kind of car should I buy?

The question of what kind of car should I buy? Electric, hybrid, conventional gas or diesel?

There are so many announcements lately, this company or that company going full electric on such and such day in the very near future. Really?

Let me begin with the fact I have been driving 3 kinds of hybrid predominantly in the last 8 years so I have some idea about it perhaps.

The Full Electric Car Conundrum

Should I or shouldn’t I jump the ship and go full electric? Both feet in, kind of just do it. Right?

Going electric has it’s advantages and some disadvantages.  Let’s see what are the cons and the pros.

The pros are:  The electric car will need less service as there are a lot less components to be dealt with. A full electric car will cost less money to run, to “fuel” or fill up and to maintain it.

Correct, these are the pros, providing it’s made half decently, it should be fine for a while.

How long? The battery pack has an 8 years manufacturer warranty so your battery pack should be fine for 8 years mostly worry free.

Keep one thing in mind it’s your responsibility to maintain a decent level of battery charge.  Meaning you can’t just leave and have your car sit for months on end.

It must be plugged in to get replenished or maintained, if you leave your vehicle for an extended period of time for any reason.

Also, a full electric vehicle is better for the environment over its entire life cycle than a gas-powered vehicle.

Electric cars, during everyday use, lower greenhouse gas (GHG) emissions than gas-powered vehicles. The electric vehicle, biggest environmental impact is produced during manufacturing.

Cons are: You will need to work with the battery range on board and the time to have it recharged.  It could take considerable time and some effort especially in the winter when range anxiety is a real thing.

Electric cars have numerous different charging rates from basic 110 v to 800v systems. The higher the voltage the faster the charging rate is in direct correlation.

Electric BMW i4


Hybrid propulsion, which is both often convenient and has a very reasonable gas mileage, depending on the size of the battery. You may use only the electric motor, especially for quick local trips like going shopping or for groceries.

There are myriad different hybrids, so you will need an expert’s advice or need to study the subject vehicle as each has their specific traits like pros and cons.

Plug-in hybrids are very convenient and will cut your fuel cost substantially.  They are fairly complex. Having dual propulsion is inevitably more complex than having one.

Most electric and hybrid vehicles will have a sub 12 volt system. Which will require a traditional battery replacement every 4 to 5 years or so, to keep the on board consumers working properly.

Electric or high output hybrids  have a separate high voltage system. Mostly 380v or higher predominantly to provide the electric motor with large quantities of stable electricity when required.

The traditional consumer operated systems are 12v only at this point onward to prevent high voltage systems getting near the occupants of the vehicle at all times for safety reasons.

Pros and Cons for Hybrid Cars

Pros of the hybrid cars are ease of use and convenience. In most cases, if you run out of electricity the vehicle can continue on the on board gas engine. Some electric cars have similar set up for instance the i3 which has a REX on board.

Cons are: You have the complexity of the dual propulsion and have a battery to deal with as well. No special interaction required except if it’s a plug in hybrid. If you drive a plug in hybrid, than you are encouraged to have it plugged in to be recharged, as soon as possibly can.

Again just like an electric car, you can’t leave the vehicle unplugged for extended periods of time, or the battery pack will be damaged. All you need to do is plug it in into the wall and forget about it for storage purposes.

Repair and Maintenance

Finding a hybrid or electric vehicle specialist in case you need it, might not be simple. Especially if you live somewhere in a small town or in a small city.

Conventional Gas or Diesel Vehicles

Then there are the conventional gas or diesel vehicles which have been through a tremendous change in the last decade or so and still going on as we speak.

Pros and cons for the conventional gas or diesel vehicles are numerous. The pros are: Ready to repair and maintain anywhere. Easy to refuel and quick to do so. The network to repair and maintain the vehicle is straightforward, no special procedure and minimal preparation required for long term storage.

Cost of maintenance spread out over time, unlike say a lithium ion battery replacement on an electric vehicle.

Cons are: Emission is greater than hybrid or electric. Maintenance is more prevalent, requires periodic fluid and component replacement. Need to refueling to keep it mobile and tend to be noisier than hybrid or electric vehicles.

There are many other advantages and disadvantages of all of the electric, hybrid or traditional consumer operated systems.   I can talk about them for hours.

At the end, you have to make the decision: Which one to buy? It’s totally up to you and your needs and maybe your location where you live.

Your decision should be based on your needs. How are you going to drive that car? Short trips, long drives, or just leisure driving?

Today’s Modern European Cars Engine

Diesel Combustion & Emission Control System Within

How does it work?

Let’s start with the combustion process, air contains 78% nitrogen and 20.8% oxygen. If it’s compressed to a small space fast, the air becomes super heated and we spray diesel fuel into the hot compressed air and we will get a combustion.

NOX gas (Nitrogenoxyde)

What else will we get? We get quite a lot of NOX gas (nitrogenoxyde) which is an irritant pollutant gas hazardous to human health.

Diesel Engine Issues

The common NOX sensor issue at hand.

The usual phone call starts like this, I have a Diesel Mercedes or BMW and my car is telling me I have an incorrect fluid in my reduction system.

Diesel exhaust emission system test and the test
results with the failed components.
Click on the thumbnail to view bigger image.

Let’s clarify a few things.
#1; Your Diesel vehicle has no AI (artificial intelligence) it has a computer system which is programmed by humans, so it can only tell you what it knows or gets feedback, so consecutively it will tell you what has been programmed to tell you.

#2; When the information system tells you your vehicle has an incorrect fluid in it, 99.99% it is lacking of SCR (selective catalyst reduction) system efficiency. It means one thing, your computer system doesn’t see the emission reduction of the NOX gas, so it will automatically default by blaming the quality of the ad blue (urea) SCR fluid as it is programmed to do so.

SCR Fluid Reservoir

Before you drain your entire SCR fluid reservoir it can be tested (by a professional) for fluid strength which has 13% ammonia solution.

The emission system on modern diesels is very complex. I could write here pages and pages how the EGR system with the SCR injection and the NOX catalyst working together to effectively reduce the amount of NOX gases.

Suffice to say, if your reduction system doesn’t work properly, or the computer doesn’t see the efficiency, due to dead NOX sensors or myriad other SCR issues at hand, will default to a single message as per above.

In case, the driver ignores the warning long enough the computer will start a no start count down, where the system control will eventually refuse to start the engine and must be towed to have it repaired properly.

Please keep a few important points in mind. Any emission component is expensive due to high tech nature, and many cases contain pricey precious metals to split or control spent exhaust gases effectively, working in a hot corrosive and hostile environment.

Any questions how may we help?
