On the face of it, it looks like the diesel pump may be out of tune. Opel Astras do smoke a bit, especially as they get old. You have not mentioned how many kilometers the car has clocked, which is an important piece of information to gauge where the problem may be. Do let me know that...

Had a similar problem with my fiat sienna weekend 1.7td..Got the diesel pump serviced from mico in worli and the same was rectified..My car had that time clocked about 55k..

The problem could be due to diesel pump or EGR valve.As the pump is ok the problem could be solved by replacing EGR valver or else the head needs to be decarbonised.

Hi ,

Also check the lube level , Is your car requiring lube top ups at around 1000 kms . When idling pls raise the rpm to 3000 rpm and check , if smoke is there then engine needs major work ie big bill
