BMW N20 timing chain and oil pump chain issues

Why does early timing  chain stretching happen?

There are multiple factors contributing to this problem, not withstanding the 8 speed automatic transmission is one of the factors in my opinion. North American drivers prefer their cars to be automatic, in this case, the automatic is more economical, than the standard version which is preferred by the Europeans.

You may ask; Why is there a problem with the 8 speed automatic? The problem occurs with our driving habits and the programming of the automatic transmission. In normal ECO mode (the default mode) it will shift up quickly and efficiently to the highest possible gear to keep the fuel consumption at minimum, hence called the ECO mode.

The quick up-shifting in daily driving will keep the engine’s rpm very low, which will cause the 4 cylinder engine to oscillate a lot more than would have been, if it driven on the autobahn at high rpm, where there are no oscillations are really present.

Naturally the chains, the guides are fairly weak design to make them light as possible. Our stop and go driving at low engine loads paired with an efficient automatic exacerbates the problem. Furthermore the extended oil changes also does not help to keep the whole thing properly lubricated for long life.

Needless to say the newer engines and their timing chains has been extensively redesigned to counter this common and often fatal problem.

In any case, if the chain makes noise it must be addressed immediately. All the components has to be replaced. For replacement, only an improved version available from the manufacturer. The replacement components must include the oil pump drive assembly as well, according to BMW repair instructions, also a revised, improved component.

There are multiple special tools required and attention to detail is essential to complete this rather delicate repair procedure properly and permanently.

4 Cylinder Late Model BMW Engine Makes a Whining Noise

Why does my 4 cylinder late model (2011 to 2016) BMW makes a whining noise?

Please note there is a technical service bulletin issued by BMW for this particular issue, which states: There is an issue with the oil pump chain which must be replaced to prevent fatal engine failure.

To get access to the oil pump chain drive the timing chain and related components has to be removed and must be renewed at the same time. There is an actual laundry list of parts which must be replaced at the same time, many of the specific bolts are stretch lock type meaning they are meant for single use only.

This is a major repair which requires considerable mechanical knowledge with numerous special tools to be done completed precisely as per BMW repair instructions.

We highly recommend to have it done by a professional only, with considerable BMW experience, who knows how and naturally having the essential special tools is a must.

We can assure you and in turn can show you all the relevant tools and documentation upon request as we do this particular and essential repair daily.

Manufacturer Endorsed Tires

The season for tire change is fast approaching as spring comes closing up.  The winter tires will need to be removed and summer or alternatively all season tires needs to be installed.

This may mean for some of us new tires needs to be purchased and fitted for the season.

Run Flat Tire

Choosing the right tire for the car is one of the most important purchase you will ever make. There is a new phenomenon which is manufacturer endorsed tires, this is a relatively new thing and mostly European manufacturers started doing it.

The question remains, could you or should you use manufacturer endorsed tires only on your BMW or Mercedes? The short answer is no, the manufacturer endorsed tires are a safe bet if you want to follow their guide lines but logic says it is physically impossible to test every single tire on every model on every make, so for the very reason I recommend to consult a licensed experienced technician with decades of tire know how to select the best tire for your fine automobile.

You should never base your tire purchase on price or impulse only.  Be cautious with large chains whom only have a wasted interest to move their stock tires and operate at volume sales at very thin margins.

The rule of thumb as always, you get what you pay for.  Same goes for advice, online information also should be treated with caution since most people rating tires are by no means experts on the field of tire evaluation.

We hope this will help to have a more informed choice.  Please visit  or call us for further details. Telephone: 905.795.0419.

We wish you all the best at Techmax Auto.

The right brake components for your BMW, Mercedes Benz or Porsche

The importance of choosing the right brake pads and rotors for your BMW, Mercedes Benz or Porsche. This is one of the most important purchase other than tires you will ever make on your fine car.

The average consumer knows little about brake pad materials or friction coefficient of the brake pads and perhaps even less about the brake rotors, brake discs. The safest bet is original brake components, but are there better choices?

Yes there are in most cases, made by very respected brake component manufacturers whom has decades of know how and engineering expertise in this field.

For instance Brembo is one of them when the big well known luxury or performance car manufacturers need a high end braking system they approach Brembo.

Brembo brake for MiniBrembo is number one they also equip over 90 percent of the F1 cars and cars involved in most Motorsports.

The only other competitor to Brembo is Akebono, whom is the sole braking system supplier to McLaren F1 and McLaren road cars. Naturally we use both respective manufacturers on our clients cars, if they are looking to improve their cars braking performance.

Both braking system manufacturer has a vehicle specific friction coefficient application which has a more ceramic composition and produce 80 percent less brake dust, so you don’t have to clean your pretty alloy wheels so often.

Please be advised! There some inferior braking products sold  over the Internet which has been imported from dubious sources and may cause permanent damage to your and others health by having asbestos in them, which is a well known fact it is a carcinogen.

Asbestos poisoning is a serious issue, which could effect your or your loved ones health, since when you apply the brakes, the brake pad material will wear off the brake pad and will float in the air which could cause lung cancer. Asbestos is a carcinogen and has been banned in the west except in third world countries.

This is a serious matter, please protect your and others health by using reputable friction materials from known accredited manufacturers.

We highly encourage everyone to choose the best available components for their fine automobile, your and others life depends on it.

We wish you all the best and if you have any questions please don’t hesitate to contact us. Thank you and have a safe trip.
