Hello I own a 2005 Seat Toledo 1.9 tdi, When your driving for a while all off a sudden the ESP, ABS, Handbrake lights (flashing) will come on, and the speedometer will stop working i.e it wont show the speed but the car will carry on driving fine. Once you have turned it of and on again a steering wheel sign comes up which goes of for a while and then the ESP, ABS and Handbrake lights come on again!! Now the ABS sensor has been replaced and so has a wheel hub or something but the problem still persists. Now is it worth replacing the ABS pump? + Does the replacement module need coding? :?
