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.

This is not as much a complaint as a request for help. Since March of 2013 I have replaced 5 throttle bodies and 3 gas pedal sensors, all oem parts. The problem that happened again today: Driving at normal highway speed [55/60] the eml, traction control and brake warning lights all went on. Pulled over and turned off. Restarted, now "service engine, eml, traction control and brake lights" were on. Turned off, restarted, same lighting situation, very rough idle and car would not drive, as it was struggling for fuel. Unplugged the "mass air flow sensor": car started, displayed no warning lights, drove fine about 8 miles to repair shop. Code read shows, "throttle position sensor", replaced..same problem within minutes of driving. A little internet research on E46 finds this an all to common problem with no solution. Thanks in advance.

Battery and alternator checked good with various service providers yet vehicle had a persistent battery drain witch would only appear after car was on the road and driving. After car stopped running due to low battery it then would not restart. No warning lights would come on until just a minute or two prior to engine quitting. Took vehicle to monrovia BMW in monrovia ca and was told that alternator was faulty. Installed new (not rebuilt) specified alternator and new battery and 5 months later same problem came back. Further own personal investigation found that BMW is aware of a faulty electrical system design flaw and I was never told about from BMW tech's at time of inspection as to the possibility of a system problem when the climate control "blower motor resistor" of "final stage unit" (fsu) and its internal resistor fails. This part has hundreds of write ups online from other owners and has gone back many years. When the part fails it leads to a whole variety of electrical problems with the affected vehicle. This could lead to a full engine shut down and lead to a crash. My vehicle has also been experiencing loss of engine coils and these are also part of the electrical system that could be being impacted by this fsu / resistor problem. Fire and or other electrical problems are also possible.
