BMW M3 Repair and Maintenance

A guide to problems, costs, maintenance and repair for your BMW M3

BMW M3 Problems

A fluid leak may develop from one or more power steering hose. When a leak is being repaired, it is not uncommon for multiple hoses to be replaced.

During tight, slow speed turning, a rubbing noise can sometimes be heard from the rear of the car. This noise is likely coming from the clutches in the limited slip differential. If the noise persists, the differential fluid can be replaced with a special oil available from BMW. On higher mileage vehicles, this noise may never be eliminated unless the differential is replaced.

The blower final stage fan resistor is known to fail. Symptoms are the heater fan speed varies regardless of the setting, the fan will not turn off when the car is switched off, or the fan will not switch on at all.

BMW M3 Recalls

Upon deployment the passenger airbag inflator could rupture, increasing the risk of personal injury. BMW dealers will replace the affected airbag inflator modules to correct this concern.

Airbags use a chemical reaction contained in an inflator module to create the pressure necessary to inflate the bags when deployment is required. These vehicles are being recalled because the front passenger airbag inflator may produce excessive internal pressure when deployed. As a result, the inflator module could rupture, causing metal fragments to strike vehicle occupants. Dealers will inspect and replace any defective passenger front airbag inflator modules found.

BMW is recalling 2008–2009 M3 passenger vehicles with the optional double clutch transmission. When rapid vehicle deceleration occurs, the transmission software may perform a multistage downshift, which can cause the engine to stall, increasing the risk of a crash. Dealers will reprogram the engine and transmission ECU with updated software free of charge.

BMW M3 Reviews

What a fun car to drive! Over 80K miles on our M3 and absolutely no problems. We have a fantastic local auto shop, Phaedrus, here in San Francisco to thank for the great experience. The car gets relatively good gas mileage too. It's too bad BMW isn't making 4-door M3s anymore.

1995 M3 133,000 miles. You know you have a great car when people still ask do you want to sell it? Have replaced exhaust system, needs minor body work a little rust hear and there, but still a great looking/handling car. Could never sell it!

Excellent all around performer with 4 seats, and is reliable. What more can you ask for?
