here i am looking for help again, feckin Skoda the glow plug light on dash is on half light when the ignition is off, i have checked fuses, relay timer and earth and everything seems fine, the only thing i can thinck of is I went through a big puddle (very big) and I thought maybe water got in somwhere so I have gave all connections a squirt of WD40 but no luck. is this an indication that i have a plug shagged?

Got sorted, dried the lot with the wife hair drier and burnt that out! what the heck my old girl is runnin write again
