Hello everybody, got a little problem with my 99 gt tdi 110. When I turn the ignition key the glow plug light on the dash goes out almost straight away, so it really struggles to start as they aren't warmed up properly. What I have to do now is turn the ignition on & off 4 or 5 times before I start it, then it starts fine. The plugs themselves are fine, I just need to know what to do to make them stay on longer? My mate reckons it's all controlled by the ECU? Hope not as there's now way I can afford a new one of these!
