Hi again every body.

This BMW (N63) start fine but gear stuck in (P) only! After diagnosed we found following codes :

1D3901 : EGS (electronic transmission control) signal evaluation (turbine speed) invalid signal content.

400626 : turbine speed sensor, circuit open/circuit short to ground.

93076A : upper startability limit reached, but deactivation preventer active.

I tried to clear those codes but no way!

Need your help please.
Thanks and best wishes.

Hello my name is Dave.

I have quite a bit of experience with BMW's and unfortunately a lot of times they are stubborn about clearing the codes without the proper scanner. Unfortunately the codes you gave us aren't coming up so I can't give you any advice as to the cause. If you could recheck the codes and get back to us we will be happy to help.

To me it sounds like the electrical plug to the transmission needs to be cleaned, if that's okay let's change out the turbine sensor. Here are instructions and diagrams. Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.
