Mein Auto: 645ci
ABS module?

Hello everyone. I have a 2004 645ci and a problem with the active steering. The previous owner replaced the steering angle sensor and I had it reinitialized and of course that didn't solve the problem. The weird thing is when the active steering fails, I also get the DSC and emergency brake light warnings too. Once in awhile the DSC will fail first and about 3-7 seconds later the active steering and the emergency brake light will follow. It was suggested to me that I try and replace the abs module with a used one . Does this sound like the next step I should take? If so, has anyone had any experience with this and have any knowledge about which ECU numbers must match to be a compatible swap? Any help would be awesome and thanks for your time.

can you post actual codes are you getting ? so we can better assist you.. Also you might want to think about getting a lap top and diagnostic soft ware . It helps tremendously , and will give you clues to a avenue to pursue in diagnosing the problem ..

Thank you for getting back to me. The car gives me no codes at all. I have a laptop but it never crossed my mind to get diagnostic software. Any suggestions on what or where to buy?

It is possible that the ring on the steering column could have dust on it, causing problems with the active steering. I would also make sure that the steering fluid is filled to the proper level. As far as the software you need, search INPA, DIS, & ISTA. Are you possibly getting a code from the ARS? Check fuses 1, & 25 in the glovebox, & fuses 66, & 68 in the trunk.

If you notice on the cluster picture ,, the triangle with the exclamation point . That symbol signifies that an error has been generated ... These cars will store error codes for just about anything ...
