Guest b_sharp Posted June 27, 2005 Report Posted June 27, 2005 Had car month or so. 2 weeks ago - car stalled on low revs. Since then car struggling for power - esp. up hill.Suspect that turbo has gone - or chip controlling turbo air intake has gone.Engine suddenly seems very rough - vibration through throttle and clutch.Heard this was a common problem. What symptoms are shown if this has happened ? Pricey to repair ? Quote
Masked Marauder Posted June 27, 2005 Report Posted June 27, 2005 It is most likely the MAF that has failed. Do a search on the site, but the best test is to unplug it (it is the first thing after the air filter housing) and drive it and see if there is a difference. If there is, then it is the MAF. Replacement elements are avialable from German Swedish & French car parts and it is a five minute, two screw job to change it. Quote
Guest b_sharp Posted June 27, 2005 Report Posted June 27, 2005 Thanks the marauder. I should've said - did try taking off the MAF - didn't have any effect. Any other ideas ? Quote
Masked Marauder Posted June 27, 2005 Report Posted June 27, 2005 Then you need to check all the thin vaccum hoses, there is one on the back of the air-box and another connected to the pipe from the intercooler to the to the inlet manifold, from the vaccuum solenoid valve tot he turbo and loads of others in between! They are cloth coated and the rubber can perish. Also if you know anyone with VAG-COM you need them to check for engine fault codes as it could be the turbo has over-boosted and the ECU has shut it down. Quote
Masked Marauder Posted June 27, 2005 Report Posted June 27, 2005 As an afterthought to all that, how does it start from warm or cold, is it hard to start? There is a known issue with the crankshaft pully slipping knocking the valve and pump timing out and if it is that then it is very serious. Quote
GSMGuy Posted June 27, 2005 Report Posted June 27, 2005 Thanks the marauder. I should've said - did try taking off the MAF - didn't have any effect. Any other ideas ? Hang on - Surely if there is NO difference when unplugging the MAF, then that is the fault, as either wat the car is running on preset values... I thought that if you unplug it, and performance dies, it indicates that the MAF is fine... At least that's how mine is! Mike Quote

Guest b_sharp Posted June 27, 2005 Report Posted June 27, 2005 Thanks for your help Mr Marauder - fortunately it starts fine from cold. Hopefully it's not the probem you describe. Quote
Guest b_sharp Posted June 27, 2005 Report Posted June 27, 2005 So guys - do you all agree that the fact that there is NO change in performance when the MAF is removed means it's the MAF that has failed ? Cheers. Quote
GSMGuy Posted June 27, 2005 Report Posted June 27, 2005 Yup! Get a brand new genuine Bosch one for Quote
