Glow plug error - car doesn't start
I've owned my 1.9 JTD GT for about 3 months now, and from day one the glow plug error light comes on the dash.
I had all for plugs changed for NGK ones, and the error went away for one or two days, but came back on. 9 times out of 10 i will get the error message appear.
Over the past month, there have been 3 occasions where the car hasnt started first time.
Being as the plugs are new, could it be the glow plug relay that is at fault?
Is there anyway of testing this?
Also, where is it located?
