Hi just a quick question I hope someone can answer , Do the none ESP cars have the Yaw and Lateral sensors ?? or are they purely there for the ESP which our car doesn't have .... got to investigate an ABS problem on the wife's A3 tonight when I get home and I'm just trying to eliminate things before I start Apparently it sounds like the ABS pump is kicking in even at low speeds and also the ABS light is on.... hoping it's just a faulty wheel sensor
