Mercedes C-Class W204 ABS pump problems
Common failure of the Mercedes C-Class W204 ABS pump and module will create multiple issues on the vehicle. Internal component malfunction of the C-Class ABS will impede the emergency braking system from operating fully and will also prevent power steering assistance.
With no or heavy power steering and only standard braking in effect the vehicle becomes very difficult to drive and potentially dangerous in emergency situations. Multiple warning lights and messages will be present on the instrument cluster including ABS, ESP, ‘Power steering malfunction’ and ‘Run Flat Indicator inoperative’.
When diagnosing the problem with scan tools fault codes will be found for control unit N30/4 ABS internal fault (5001, 5944 and 5945).
Typically when looking to resolve these Mercedes C-Class ABS problems you may seek to order a new replacement ABS direct from manufacturer. This is very expensive and you may also be charged for SCN coding or adaptions to be run.
We have a better solution –ABS module, pump and motor repair.
