Nice diy. Very well detailed.

My car only shifts R, N and 2nd. This happened after hitting a road pothole. It already happened before and came back to normal after sitting in the garage for some weeks or after hitting another road bump or pothole. This lead me to think to be more related with a electrical issue than mechanical but my local dealer wants to replace the whole gearbox. By your experience, can you give me some directions to start looking for the real cause of it?

Btw, in 4 year i already replaced the hidraulic pump due to overheating symptoms that lead to gear poping out to neutral for +10sec, and 2 years later with the hpf clutch installation, the replacement of the gps and the compression springs as a preventive maintainance.

As for SMG stuff, if you ever have an issue with yours, PM me I read the hundred and some odd page technical manual from BMW on it and have a pretty good handle on troubleshooting them.

My Ride: BMW 330ci
Hello Road Trip

Hello Road Trip...

I came across your DIY when I searched using this query "4EF6/E1 - Sensor clutch position".

My 2004 BMW 330Ci (SMG) has been in safe model for several weeks and I do not know the cause.

I did recently replace the alternator and the battery is new.

I have attached an output log from a BMW Scanner (v 1.4.0).

I am wondering if replacing this switch might possible fix my safe mode issue.

Any thoughts/guidance/suggestions would be tremendously appreciated!

Thank you Road Trip!
