Two problems related to automatic transmission torque converter have been reported for the 2001 BMW 330. The most recently reported issues are listed below.
I just bought my 2001 330i BMW two months ago with 103,000 miles on it. The check engine light came on and the dealer says I need a new torque converter. They want $2000 to put a new one in. I then looked around here and saw that this is a common problem. Also I had to change two of the window regulators. - another common problem with BMW. Is BMW doing anything about this? why does BMW make the public pay for the problems they made?.
Design flaw in transmission, specifically the torque converter, on 2000-2002 e46. Requiring rebuilding and or replacing torque converter. BMW is aware of problems and is widespread.
