Hi all, i am new on here so any help would be greatly appreciated!
I have a 2003 Astra 2.0DTi SXI 16v, this is my third year of owning the car and up until now i have had no major problems.
recently when starting from cold the engine seems to violently judder just before firing. I thought this may have been caused by worn out glow plugs or dirty air filter but after servicing the juddering on cold start up is still there.
once started the car runs smoothy with no problems, and when warm it starts as normal. Just when the car has been left overnight and from cold this juddering happens.
Any suggestions as to what this could be?
