Iv had vsc light come on last week, left it in for service. They infomed me its all related to problem with head gasket, and this in turn is linked to vsc light coming on. Other problems withthis include blower only blowing cold air when on hot, coolant low level and fan in engine coming up needlessly. Bad batch of engines in is models made in poland around 2008. Bringing mine, is220d to garage tomorrow to see about getting it fixed hopefully out of goodwill gesture because of above. They said full FSH is one condition and under 110,000 miles is second condition. My car is 57 reg, is220d with 93,000 on the clock. Will keep you updated.
