hello I have a class s320cdi 2007 I had the abs esp light unavailable and the car tends to restrict it at 3000 rpm and as soon as I let go of the accelerator it gives small gas costs on its own. I ran it for diagnostics and changed the rear abs sensor but the car still has the same faults. What should I do ?

Check for wheel speed sensor, it seems like car is not sensing that car is in motion.

GOOD CONTENT......BUT DAMN!!!!! GET A TRIPOD
Watch my videos in which i used Tripod. :)
did you have to program the new abs module?
If you have hardware and software versions same then it will not ask for. If the software is different then definitely you have to program it.
Where do you check for hardware and software version?
