Can anyone help with some advice, I have a P reg Sharan TDI & periodicly the glow plugs warning comes mainly if I have been stopped in traffic a while. This does not happen all the time, just intermittently.
If I turn the car off/on the warning goes which suggests an electrical fault I guess. The car does not suffer in performance when this warning appears (touch wood!!).
Any ideas / suggestions?
thanks
Mark
