big boy stevie Posted July 13, 2010 Report Posted July 13, 2010 hi guys i have a 1.9 tdi 2002 115 zetec, i drove the car down the motorway at the weekend and it was very slow you could hear turbo wistle but no assistance from turbo it felt like it wasnt working, pulled cover off next day to see if i could see anything ie pipes off or anything and couldnt really see turbo looks like might be easier underneath nothing found really, following day i drove it and car was back to normal pulling like a train and yesterday i drove again and its back to be slow again, does anyone have any ideas on what it could be, only thing ive done is put a shot of redex in it when i last filled up, could it be ive dragged up some crap and it keeps going round the system or just a coincidence praps. any help appreciated many thanks steve Quote
Delboy255 Posted July 13, 2010 Report Posted July 13, 2010 Assuming filters are in good condition and wastegate valve not sticking, next suspect would be MAF sensor (on air intake). Quote
big boy stevie Posted July 13, 2010 Author Report Posted July 13, 2010 been as good as gold today very strange indeed, i will have a look at filters and when the weather gets better i will have a good look at turbo and wastegate. thanks for reply steve Quote
