I destroyed my EPS with an unfortunate slip of my floor jack a month ago. In the process, the bottom electrical connector (BOSH6P-F) took the brunt of the force, and was also destroyed.
After finally locating an eps motor with a matching part number, and soldering on a new connector, my car still has zero communication with the EPS unit.
A month ago, when I last drove the car, the EPS worked perfectly, and I have no reason to suspect a problem anywhere else in the system other than what was damaged by my jack. The only two things that have changed since then, are the replacement eps unit from a 2018 330e, and the Bosch 6 pin connector that I replaced. I'm trying to figure out what is causing my car's lack of communication with the new unit. It seems to me that the cause could be one or both of the following things, but I don't have a way to find out.
Either: I did the worst possible soldering job of all time, and the joints I made aren't conductive, or;
The seller who I bought the unit from sold me one which isn't functional.
I understand that the new unit needs programmed to my VIN number, and then the standard service functions performed/coded, but I can't get this done without being able to communicate with the unit, it seems. I have ISTA, E-SYS, and Psdzdata full, but do not know how to use them. If anyone has any advice, I would be eternally grateful. If anyone here felt like jumping in and taking a look, I'm happy to give access via Teamviewer or Utraviewer. Thanks in advance, my friends. I do hope to drive this car again someday.
