Q: ABS, ESP, EBR malfunction

asked by on

Fault codes from my Snap-on Diagnostic tool: -7208 check codings in control module Engine control module -5944 Control unit N30/4 (Electronic Stability Program control unit), internal fault -5945 Control unit N30/4 (Electronic Stability control unit) internal fault -5001 Control unit N30/4 (Electronic Stability Program control unit) internal fault

I'm pretty sure i need to replace the ABS/ESP control module. But, what would be needed to code the new part to my vehicle? Star diagnostic device?

My car has 93000 miles.
My car has an automatic transmission.

You’re getting into an area that is kind of a dark art when you’re getting these kinds of codes. While I don’t know any of the symptoms that the car is exhibiting, I can tell you that failure in one of the control units can lead to codes showing up in the others and the ABS, ESP is a likely culprit since it interprets the wheel speed signals and sends the information to the other modules. You’re right that the module has to be coded, and I don’t think that Snap On has the software for that so the only place to go is the Star Diagnostic. (The consumer version of the Mercedes SDS ) You can Contact YourMechanic and see if anyone in your area has the appropriate equipment for this. Otherwise, this may be a case that would best be consigned to the Mercedes Dealer.
