matth76 1 Posted May 8, 2007 Report Share Posted May 8, 2007 HiMy gf has a new (53 reg) 1.2 polo (not a vr6 I know but someone on here may know what the following problem could be). Today the "exhaust emissions warning" light started flashing and the car is all juddery... at idle and at speeds up to 60. Above that it gets smoother. The exhaust vibrates a lot. The car has absolutely no oomph like it used to. Any ideas? I suspect it could be the MAF or lambda sensor/oxygen sensor...if it has either. It certainly seems to be some kind of sensor related problem. Could possibly be a vacuum leak but unlikely or something to do with the cat. Car was running fine until today. Going to ring round some local garages to see if they can put it on vag com and do a diagnostics check. They should do it for free (as its a two min job) but knowing the garages round here I doubt it...vw main dealers are even worse. Anyway if anyone knows what the problem might be or has seen this happen before this will arm my gf with some "knowledge and ammunition" when she goes to the garages to see what they say.Cheers for any help.Matt Link to post Share on other sites

matth76 1 Posted May 8, 2007 Author Report Share Posted May 8, 2007 Hi tonyThanks for your reply. It's done about 45k miles. Yeah it's a 3 cylinder. Warranty just expired unfortunately. Would exhaust valves be an easy job to sort!? I know a local mechanic who could do it cheaply (family mate) if it's fairly simple to do.Car is drivable but just drives like a tractor. gf needs car to get to work. Will continuing to drive it cause any damage or make it worse?Cheers Link to post Share on other sites
beefvr6 0 Posted May 8, 2007 Report Share Posted May 8, 2007 hi m8 i work for a garage myself, we've just done one of these and it ended up needing a coil a cat and a lambda sewnsor. This was because they kept on driving it with the same syptoms. I would agree and say coil! Link to post Share on other sites
c4mbl 1 Posted May 9, 2007 Report Share Posted May 9, 2007 fairly new car to be needing a coil is it not?I was gonna say Lambda, you can easily check that urself visually. Link to post Share on other sites
