My 98 W202 C200 has recently had 2 failure to starts. The engine turns but doesn't fire. The first was in a petrol station and I see this matches other posts. Both times it fired eventually. My expertise is limited to changing the batteries in the key fob, which I've done following other related threads, so I'm not asking for solutions. As I'm overdue for a B service, and the main dealers around me are particularly expensive, is there a good indy in South Bucks, ideally near Beaconsfield?
