Off side rear wheel sensor.Only half off! Hello people. Got it scanned and Audi diagnosed it as the rear off side wheel sensor as guessed by many of you. I got to replace the rear wheel sensor on my '99 TT but am having real trouble getting the old one off. I've managed to get the 5mm hex allen key head thingy out from the back of the hub and assumed the sensor should now just pull out of the hub, but it's stuck fast and as it's quite inaccessible I can't lever it out. Am I missing something or is there a knack or trick to removing the sensor? Cheers P.
