Three problems related to engine and engine cooling have been reported for the 2009 BMW M3. The most recently reported issues are listed below.
Takata recall driving my car for about 30 minutes on the local street and stopped at a red light, light turns green, I try to accelerate and engine felt sluggish and shuts off. Towed the car to mrf engineering and car needed an "engine replacement" as my rod bearings caused the engine to fail. Costed roughly around $19,000 in parts and labor.
The car suddenly vibrated and the wheels locked up and skidded slightly sideways before going into a reduced power mode. If it had been raining or snowing, or at a higher speed on highway the situation could have been deadly. I had the car taken to the dealer. I was told a the throttle actuator valve was defective. The car has only 44k miles but has surpassed the 4 years of warranty. This is a known issue with thousands of cars affected. BMW refuses to recall and repair the item if the car is not under warranty. The cost for repair is $3000. 00 the part alone is $1200. 00 which I was quoted. My vehicle is also affected by the takata airbag recall.
S65 v8 engine in a BMW M3 e90/92/93 and m5's with a v10 has two throttle valve actuators that fail prematurely at 40-80k miles. Both the internal nylon gears and electronics will fail, affecting accelerator pedal response and causing hesitation, especially with the dct transmission. These parts are not a maintenance item. When failed, the engine malfunction, excess emissions, skid control, and abs braking warning lights are triggered. Engine goes into limp mode. This is dangerous when it happens while driving in rainy, snowy, and icy road conditions. The throttle valve actuator design defect should have triggered a BMW recall. Replacement parts are $1000-1300 each plus $1000 labor and have never been redesigned by BMW/bosch. So the replacement parts are also defective and will fail prematurely. Repairs occurred on Dec. 2012 at 80k miles for $2000 and on Jan. 2016 at 140k miles for $3000. A BMW M3 and m5 recall and redesigned parts are warranted. BMW technical service bulletins should be issued for this design flaw. 8yr/80km federal emissions warranty should cover these repairs as well.
