Hi

New to the forum and looking for some advice.

I'm getting ESP, ABS, Diff-lock system malfunction, and Diff-lock overheat messages from my 06 W164 ML320.
I get this as soon as the car is started and is sitting in the drive so plainly the diff can't be overheating. My local guy (and he's pretty switched on) has looked at it and reckons it's not a wheel speed sensor and can't find the fault.

Any suggestions greatly appreciated........

PLEASE LET ME KNOW WHAT PARTS ARE TO BE REPLACED

 

Hello and welcome to the forum! Have you tried pulling the codes? If you have a MB code reader, this should give you a pretty definitive answer as to where the issue is originating. Was your local mechanic able to do this?
