C220 Cdi 2009 estate , problem with abs traction control and run flat inoperative

[Stephen Forster]

Hi guys , had warning lights come up ,Traction control, abs, run flat inoperative and no cruise
Had car scanned
Came up with no wheel speed signal coming from resr os. Had speed sensor changed but problem still there . Any ideas ??

Presumably you don't have your own scanner?
Is it possible to take live wheel speed sensor readings? If so, this might give you better info.
Sometimes the plug to the wheel speed sensor, under the wheel arch, can have poor connection. Worth checking.
Do you have an esp light on?

It could be the pickup ring , where the sensor is reading from , 2 it could be wiring or 3 it could be the ABS ecu ( unlikely )

Genuine part or aftermarket? Known aftermarket not to work as slightly different length.

Dual post Ian, he said elsewhere he used aftermarket so I reminded him of the error of his ways....

That sounds expensive buddy ?

I'd be getting a second opinion...
