I recently bought my s3 with the traction control light on and it won't turn off. the front wheels just spin in the wet and it has no grip at all. i have scanned it with vagcom and its bringing up "lateral acceleration sensor" circuit failure. i cleared the code, went for a spin and the fault code came back. would this sesnsor being down cause the quattro not to kick in?? i have searched some posts on here and i have checked the earth strap on the haldex unit on the rear subframe, the strap is in good condition. i have located the lateral and longitudinal sensor but i havent swapped them over yet to see if the code changes from lateral to longitudinal. i will do this tomorrow and report back. can anyone advise me where to go from here? what tests can i perform, what can i clean, remove check etc. i really want it sorted as it doesnt handle well amd with the revo remap the torque steer is terrible. any help would be greatly received as its doing my nut in slowly.
