I've had the balance and alignment checked, but with no luck. I don't really notice it now anyway. I'm more worried about when it's going to develop the MAF and electric window problems; I've already had the rear washer pipe popping off and knackering my boot catch. Mine's a company car, just out of warranty, so i can't really catch this faults before they bite me in the ass, no lease company would pay for things that haven't gone wrong yet! But so far, so good!
