hi guys
searched loads and read loads
ive got a W204 2007 c class
got the abs, esp, run flat errors
checked with star this said it was the rear right rpm sensor vidually inspect.
so bought a new genuine part
installed and cleared faules. As soon as i started driving my lights were back on

ive read it could be bearing and abs seals
can anyone confirm this please ?

and if they have part numbers for genuine mercedes parts pls

also read you have to disable SBC module !

any steps and how to’s would be greatly appreciated

thanks

thanks mate

got a second hand hub on its way complete from a working car
ill put my new sensor

do you know how much a new bearing would be ?

dave

I rang mercedes up and spoke with their parts dept, he informed me there is a ring behind the bearing on mine 2007 that the abs sensor gets its readings from. So i went and bought this and will fit it tomo sometime.

thats it yes
impulse ring
im hoping it sorts it out.

fingers xssed

All sorted guys
