  1. Hi i have a golf 5 R32, and lately at startups the electro-mechanical power steering light goes on. after a number of startups the light goes off and power steering is back. This light does not appear while driving but only at startups. everything else in car is working fine and it doesnt seem like battery is low. I have a feeling theres somthing wrong with the steering rack. Can that be the problem? can u please help me? and would replacing a steering rack come under warranty? thanks
