9CB4 rear ride height sensor fault
9CB4 - Rear ride height sensor, faulty.
Hi. I've replaced the rear sensor but when scanning the car i can't get rid of the fault code. The symptoms were the headlights moving up and down while stationary and driving. After replacing it , everything's fine apart from the code persisting. I have tested the voltage on the connector thats directly plugged into the sensor its showing 4.77v. The battery and all lights related fuses ok. Tested everything on inpa and it came out that the FRM module is faulty (?) But no codes related to this. Any ideas on what ot could be? Thanks. |
