hi there first off what a great forum ,i own two vauxhaulls ..both diesels ,so no doubt will be visiting regualary
,allthought my wifes astra dti will most likely be the car we attend meets in !
ok well ive owned this astra estate turbo diesel for a while its the gm 8valve diesel turbo engine , and whats been happening is i start from cold car is ok for first 5 mins
then without fail every time ,the rev counter stops working ,
engine light comes on and the car starts hunting ,or surging , it will keep doing this untill its left to go cold usually a very long time , then it will start all over again ,
i did take it to a deisel place that said they wanted 100 pounds to diagnose ,but from start he heard it doing the rev thing ,and said its most likely fuel pump and wanted 500 plus vat to recon it , i wasnt overly enthused with his diagnosis ,so i went elsewhere
they pluged it in and it came up with 3 faults , no speed signal , poss egr fail ,and fuel pump ecu fault ,but the engineer said it could be either one of them or all three ,
anyhelp would be much appreciated thanks in advance paul !
