Can anyone help me please.The ABS comes on if the brakes are applied when turning right. This 1993/4 9000 has been to the main dealers 5 times, and they have been brilliant. but neither they or Saab GB can find the fault. The abs control box,pump, pistons,master cylinder,servo, all wheel sensors have all been replaced. I changed the frt off side wheel brg and I thing the other side has already been done.I cant find anything wrong.The Saab computer says the system is perfect!!
