my sapphire drives fine, brakes work fine. abs light comes on on start up & goes out nearly straight away. abs light comes on though when I take it past about 130 mph ( on a track obviously)
any ideas?
was thinking that a sensor resistance may be slightly off but not enough to show up a big enough speed difference to put the light on until i get to about 130.
all sensors have been cleaned etc any other ideas appreciated

 

Mine would come on at 90 on my private test track, it was down to a damaged pickup ring on the OS CV joint. Remove the ABS sensor & using a torch you should see the toothed ring. A couple of the teeth on mine were bent over.
Replaced the joint & no problems since.

 

cheers for that, thinking about it it was working fine up till replacing the complete front passenger side hub assembly & shaft
