Having problem with traction on my S3-2002 plate. Have P-Zeros fitted but still in wet the wheels spin and now in the snow have to leave at home as she gets stuck on the slightest incline. On checking on ice/snow to see if Quattro is working only front wheels spin. Have checked fuses all seem fine. Are other S3/Quattro owners getting this same lack of traction or is it just me. My S2 pictured use to work a treat, loved the snow. But S3 a real disappointment? and i feel it should'nt be. Any advice or response welcomed!
