Getriebeprobleme (Kein Gangeinlegen möglich) - 750Li

[Pat_DE_US]

Hallo zusammen,

Ich kann bei dem BMW meines Kumpels keinen Gang mehr einlegen. Ich habe auch schon alle Dichtungen und Batterie gewechselt die normalerweise das Problem verursachen. Ich lebe in den USA und habe daher schon in ein anderes Forum gepostet, daher kopiere ich einfach den Text. Bin fuer jede Hilfe dankbar!

So I am about to go crazy with a friend's 2006 750li. It is stuck in P and won't go in N, D, or R. I work a lot on classic cars in my shop, so I am not very used to all the electronics in the newer cars but I am doing my best to learn. That being said, I am just trying to help my buddy out here to save him some $, but I'm at a point where I'm giving up. So I really need your help here guys. Please!

I have been browsing through this forum for the past two weeks and afterwards it was clear to me that changing the Transmission Mechatronic Sleeves should fix the problem. So I got a repair kit and followed all the instructions found on here carefully. The bridge seal adapter was in bad shape so I was sure that is the issue. I did not change the 4 round ones in the middle because they looked fine to me. Unfortunately still the same problem, it won't go into any gear. So I took it apart again and measured the resistance of the solenoids, and even though it all appeared to be fine, I ordered the original parts from ZF and also replaced all of those including wire harness. Unfortunately this did not solve the problem either. There was also no metal debris in the transmission pan so I think the actual transmission is fine. I also followed instructions on how to fill in the oil.


I am seeing the following error messages in the display:
Parking Brake Malfunction (I looked into that and the gears in actuator are broken)
Brake and Drive Control System malfunction
DSC Malfunction
Flat Tire Monitor Unavailable
Passenger Belt Fastener Malfunction
Washer Fluid Low

Then I setup INPA to be able to read and clear all codes. I attached the error codes here. I am receiving:

Transmisison:
507C
51AD


All control module:
EGS 51AD
DSC 5F20
EMF D3BD
EMF 6044
SSBF 97E0
DME/DDE 29DD
CAS A0B5
KLIMA 9C64
KLIMA 9C7A

I did research on it but I am not sure what all of that means, so I am hoping on your expertise here. Any ideas what the problem is? I am out of ideas... Thank you!!!
