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.

2003 BMW 325 Owner Comments

problem #1

Oct 092007

325 6-cyl

  • Manual transmission
  • 37,500 miles


Double vanos system on several models of BMW from 1999 to 2006, have defective vanos systems. The E39 double vanos (variable valve timing unit) has a malfunction problem. This double vanos can be found on 6-cyl engines M52tu, M54, and M56, found in several model cars, E39, E46, etc, years 99-03. The malfunction symptoms are almost all subtle and mostly go unnoticed. They include lower gas mileage, lower performance, degraded emissions control, and possibly others. The M52tu engine (99-00) has one further malfunction symptom which is far from subtle. It occurs on cold weather cold engine starts and takes the form of repeated engine attempted stalls and possibly a complete engine stall. The engine rpms drop dramatically and then recover. This then repeats after a few seconds of steady idle. The problem can be more definitively diagnosed by disconnecting the vanos intake or exhaust solenoid electrical connector.
