Hi Rianvs
Thank you for kindly taking the trouble to describe in detail your experience with flashing glow plug lights.

My problems are ongoing. After a previous problem in which the car stopped altogether I was told it was the diesel pump. I got one second hand and it was expensive to fix.
Even then things werent right. The flashing glow plug symptom soon became apparent, and then the car one day wouldnt restart after the flashing gp light.
Even now the car is with the mechanic. I may print out your kind posting and show it to him. He has had the car 2 weeks.
Please may I enquire is the positioning sensor of the cam difficult to do?
Yours with thanks
Ian
