i have a 2001 audi a6 quattro 2.7

abs kicks in at low speeds, i am stumped!

i changed the RF wheel bearing there was a tiny bit of play in it not much. all other bearings have zero play in them

changed all 4 abs rings on the axles - none looked bad but i changed them anyways

viewed abs wheel speed data - my scanner is a genisys and supports the vag com, i didnt see any of them acting up

i dont know what else it could be....should i start replacing wheel speed sensors?

thanks,
Russ

 

You have covered all the obviouse problems . I do not believe the sensores just fail.

I had a similar problem which turned out to be a piece of string wrapped around the stub axle.

 

im wondering if anyone has seen a faulty module or wheel speed sensor cause this before i start buying more parts?

thanks,
Russ
