Motor Work On BMW

The right tool for the right job. Correct? This sentence apply for motor work on BMW Merced, Porsche, and on MINI to.

Motor work on BMW, Porsche, Audi, Mini.

Having the right tool for the right job is essential in most cases. No shiny toolbox will ever fix any BMW if doesn’t have the right tools within.

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.

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.

Long behold the rear defroster staying on permanently.  Bingo, the module is staying on for good, she is locked on permanently as you can see on the above Flir image, it’s very colorful  from the heat emanating from the current flowing thru it.

Case closed temporary,  we disabled the rear defroster until new module arrives. Client is happy, issue has been resolved, his BMW back on the road.

It is heard of: If the rear defroster on all the time, it can do more then kill the battery. If a defective defrosters heats the rear windshield all the time, it might explode, because the cold and hot combination. So it worth to keep your eye on it…

You can do several things if something like this happens with you, the first one, give us a call, and we will do the rest.

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

Hybrids

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.

The racetrack oriented 2020 AMG GTR-PRO

This week’s rare visitor was one of a kind, 2020 AMG GTR-PRO.  You can get this car for a quarter million dollars. The racetrack oriented PRO as the name states is fully “carbonated ” everywhere notwithstanding super-light forged magnesium alloys and weight optimization to the max. Carbon fiber torque tube from the engine to the transmission at the rear axle, dry sump lubrication and endless lightweight goodies.

577 Horsepower

The   R-PRO meant for race for the pro drivers only. Oh and not to forget your race license naturally. Why for pro drivers only? Because if you want to drive this car, you need lightning quick reflexes with exceptional driving skills to harness anything over 4 hundred horsepower on a rear wheel drive platform. And the AMG GTR-PRO is a rear wheel drive. Puts out solid 577 horsepower, and 516 pound-feet of torque. I would suggest driving gloves, because to wrestle this monster under your control will produce some really sweaty hands.

The GTR Pro comes with a 4.0-liter twin-turbocharged handmade (AMG formula one man one engine)  V-8 engine,  which is enough for 0-100 km acceleration in 3.5 seconds. The top speed is around 310 km/hour.

Only 150 ever assigned to the entire north America and the  car on the photo is 1 from that 150.

One Cracked AMG Rim. Unsafe to Drive.

The winter is almost over, but you should not change your winter tire yet.  There is a down side to driving on all season tires  on snowy, icy road. Some of our clients find this out on the hard way.  A small mistake might be very costly.

Every driver should know: Smaller the tire’s tread, smaller its biting edges and your tires will have less traction. For reliable braking and cornering performance at winter driving condition, on wet, snowy and or even icy road, you need good quality winter tire, not worn down all season tires.

The weekend weather took it’s toll, one cracked AMG rim. The replacement rim cost $1570.00 from MB, one bent alloy for late model 530 BMW cost of replacement $1230.00 + alignment.

How do you check a rim for any possible damage?

New wheel has arrived nice and shiny. Now the question remains: How do you check the other rims for any possible damage? In our high tech world, we have solution for almost everything. Meet our laser guided 3D tire balancer, check the next video out.

Yes, there was one more rim which is wobbly for now we made the best out of it. We do this all the time. To be able to make a smooth ride you need a precision machine which can pinpoint rim or tire defects and recommend match-mounting by dismounting the tire and remounting it to a specific spot on the rim to bring the highest point of the tire to the lowest point of the rim to get it close as possibly can to perfect.

Laser Guided Made in Germany Alignment Machine

Let me note it: This is our second machine of the same made. We use the first one about 20 years. Yes this balancer is 23 thousand dollars but precision and technical innovation has its price. We actually take it one step further by marking each wheel with their precise run out. It goes like this, the best wheel to the left front, 2nd best to right front, 3rd to the left rear and worst is the farthest away from you the driver.

Naturally when your wheel looks like the one on the video, with the multiple bubbles are toast, unsafe unfit for any use.

One of our other clients, bent his AMG suspension driving on summer performance tires. Even though his car is a 4 wheel drive, it was no match for the weather.

Why does my engine burn oil?

Explanation continued in here, ICE (internal combustion engine) has been around for over a hundred years. Since the last oil embargo in the eighties governments decided to try to limit the amount of fuel being consumed by the engines. Later the EPA (environmental protection agency) started enforcing CAFE (corporate average fuel economy) to force the manufacturers to reduce the fuel consumption of the automobiles. Car manufacturers had to pay penalties so at the first opportunity the manufacturers decided to start with a clean sheet of paper immediately.

BMW N52 Engine

In the case of BMW it was 2006 with the E90 platform and N52 engine which was first time ever was designed and build with ultimate efficiency, the first of their new iteration of the efficient dynamics slogan.

Naturally the fuel economy standards kept getting more strict so they enacted accordingly which brought us to the new turbo era of the N55 and N20 engines. Let’s go back to the question why does this modern engines burn motor oil way more than the previous models decades ago?

This is all due to the maximum effort to provide fuel efficiency at the highest possible level.

How does all this work?

The N52 introduced the valvetronic system, the N55 introduced a refined version paired with twin scroll turbocharger and direct fuel injection. This all helps the ICE to operate at it’s highest efficiency level at any operating conditions. Naturally all the internal components has been reduced to the bare minimum and every component has been redesigned for minimal friction.

This is where the oil consumption comes in to the picture, by reducing the piston rings to the bare minimum, and reducing the piston ring tension to the same minimal pressure. The piston rings if just ever slightly get carboned up by infrequent oil changes or poor quality motor oil, just by topping it up cheap oil will jam the oil ring and the engine will start to consume more and more motor oil burning it up in the combustion chamber.

BMW N55 Pistons

Here are some relevant pictures of the N55 piston, as you can see the rings are extremely thin and the oil ring tension is next to nothing.

N55 also has a variable pressure oil pump to further reduce the internal load. Additionally the camshafts are hollow and the engine has been specified with a light weight motor oil to reduce the pumping losses even further. If you look closely you can see the rings are like stairs looking at them from the top down which showing the compression ring protruding out the most. The oil scraper ring in the middle is less so, and the oil ring at the bottom sticking out just barely which accounts for the least amount of ring tension.

Maintenance with The Best Lubricant

To make this jewels of engineering last some considerable time you need to give it the best possible care. Maintenance with the best lubricant you can afford and that should give you minimal oil burning and maximal peace of mind.

This is as always, a double edges sword, the clients want maximum power, the manufacturers are there to sell cars, and the government wants efficiency. It’s a difficult fight, a kind of tug of war to have your cake and eat it too, so to say.

I hope this helps, any question, how may we help? Call us for more details. Telephone: 905.795.0419
