Hi - I’m new to the forum but wandered if anybody can give me some advise. T6 Caravelle was running fine but glow plug light started flashing and engine lost power so pulled over and switched engine off. Tried restarting and although the engine turns over, it won’t fire. It’s been in an independent garage for 3 weeks now and they still haven’t identified the issue. Are there any recommendations for a good independent VW specialist in the GU14 area?
