Oh right guys, so I recently changed the rear differential cover after it got hit and broke. So I went a head and ordered a new rear cover for the diff and installed it. i put new fluid on it and turn on the car and got a rear axle differential lock warning on the screen.( No yellow or red engine lights) . So we put the Asys on the car and these are the codes it got.

Codes:
-482BA6: Servomotor, actuation positive engine terminal and negative engine terminal wires mixed up.
-482BAB: Plausibility fault in servomotor movement .

After I saw the codes I went ahead and replace the servomotor and diff lock module to see if that was the issue but it did nothing. No changes after we put the new servomotor and module.

Is there maybe a fuse on the car that can be causing this issues? I want to see if i can check something else before I buy new differential.

Thanks for any help

I suspect you mistakenly posted this in the wrong forum (Z4 G29 forum). For a '13 335is, try the E90, 91, 92, 93 forum.

Thanks for updating what you drive.

My suspicion is that a cable got damaged. It may have blown a fuse because of a short, or no power to the module/servo.

I would probably pay to have it diagnosed, if you cannot find any damage. I don’t know how much a set of electrical schematics would be for this vehicle - I’d be afraid to ask, and then afraid to open it!
