Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

Excessive soot and carbon build up in the intake manifold and intake valves of the 335D which is a diesel car. This causes rough idling, misfires, and loss of engine power. While merging onto a highway, the engine malfunctioned due to this problem and immediately lost power almost causing a collision. The vehicle has had this problem for more than 20K miles and continuous trips to the dealer to diagnose. Finally, the dealer agreed it was carbon build up but that it is not covered. The repairs for this should be covered by BMW as it is emissions related and can cause significant engine problems. This has not been an issue on other diesel cars by other manufacturers.

Driver side floor mat curled up at front and was captured by clutch pedal when changing gear. When clutch was again engaged, mat was pulled up and interfered with subsequent brake operation before freeing itself and falling back onto floor well. Since problem was intermittent, it took a while to figure out.
