Guest Andyjflet Posted July 2, 2004 Report Posted July 2, 2004 I'm not an expert but me thinks some of the members on here will have something to say, have you tried buying a new MAF sensor first and testing that out....could save you Quote
hampstead Posted July 2, 2004 Report Posted July 2, 2004 The suggestion that a faulty MAF sensor could result in a blown turbo is interesting...anyone know if there's any truth in it? I've only had my TDI 110 for about 3 weeks, and having nothing to compare it to, I decided to unplug the sensor yesterday just to see if there was any discernible difference - the performance is better with it unplugged, which suggests the sensor is duff. I can't tell how long it might have been like that, though. Being cheapskate, I thought I might run around for a while with it unplugged until I decide whether to bother replacing it.

Guest spanner137 Posted July 2, 2004 Report Posted July 2, 2004 just replaced my sharan, full tdi engine from dealers only 1400+ vatturbo 500 + vat ITS turbos Leeds Quote
Denis Posted July 2, 2004 Report Posted July 2, 2004 The suggestion that a faulty MAF sensor could result in a blown turbo is interesting...anyone know if there's any truth in it? I would not claim to be an expert but it sounds quite ridiculous to me! Quote
Ivor_E_Tower Posted July 2, 2004 Report Posted July 2, 2004 It is ridiculous. Duff MAF sensor will not harm the turbo, it will just confuse the engine into running with "odd" parameters, none of which could affect the turbo. Turbo has bearings and oil feed, and runs off the exhaust gasses passing through it. Oil is supplied by oil pump (I hope) so will be unafected by MAF failure. Composition of exhaust gasses wil be affected by MAF failure, but the ECU should default to a "get-you-home" mode if MAF fails catastrophically. Turbos are usually around Quote
Guest nimrod Posted July 2, 2004 Report Posted July 2, 2004 Well after five MAF sensors and only one turbo due to bearing failure! (not on a Galaxy) I cant really see the link between MAF failure and the death of the turbo! unless the MAF sensor got sucked through the intake system and got chewed up by the turbo! :o nah! cant see that happening :lol: replace the MAF and see how you get on, if the performance picks ups and stays consistant, you just saved a lot of money :D Quote
fivenecks Posted July 2, 2004 Author Report Posted July 2, 2004 i will be picking my car up tomorrow until i make my decision,and i will ask him properly what he means. would the maf sensor stop the tubo kicking in..he said that when you try to overtake someone and even going up hill it struggles no power? i will let you know tomorrow when i see the bloke. thanks Quote
fivenecks Posted July 2, 2004 Author Report Posted July 2, 2004 or perhaps i have just bad luck with the maf sensor gone and the turbo gone aswell... car only done 26000 miles lol Quote
fivenecks Posted July 2, 2004 Author Report Posted July 2, 2004 can they do recondition turbos? Quote
Guest nimrod Posted July 2, 2004 Report Posted July 2, 2004 can they do recondition turbos? yes Quote
seatkid Posted July 2, 2004 Report Posted July 2, 2004 The 110 bhp turbo is a variable geometry design. IIRC the exhaust direction is varied to regulate the boost and I don't think it has a waste gate. I have read that incorrect control parameters can cause the closed loop control to run away and is a design problem with VGT turbos in general. In this case the MAF is a critical component in protecting it. This might be what happenned... Quote
Guest Andyjflet Posted July 3, 2004 Report Posted July 3, 2004 Fivenecks, I think you should just replace the MAF sensor first and see what happens, I have a feeling you may be pleasentlet suprised ! Quote

Ivor_E_Tower Posted July 5, 2004 Report Posted July 5, 2004 Yes, simple DIY job. Just unclips IIRC Quote
dead fords haunt you Posted July 7, 2004 Report Posted July 7, 2004 :P they must be taking the piss unplug maf and just see :blink: if they are right do the job yourself <_< you were smart enough to buy a gal :rolleyes: :unsure: Quote
fivenecks Posted August 11, 2004 Author Report Posted August 11, 2004 just to let all know .... I had the maf sensor done first and was great better than before.....but there was still a little hesitation round about 2500 to 4000 revs.... so i had the turbo done and now goes like a rocket with no hesitation. and also the engine sounds quieter now ....running right....
