Can anyone help please......... I maintain my own vehicles and have done since I was 17, 35 years ago. I have a problem with my 220 CDI Estate, on cold start the glow plug lamp lights, the engine starts and runs fine, but a few seconds later the lamp comes on again for perhaps 10 seconds. I havent owned the car long and it has only just started doing it. The weather has turned cold 5 to -2 degrees. Is this normal or does this indicate the glow plugs need changing. The car is nearly 4 years old and covered 55000 miles.

Thanks in anticipation. Delboy
