Guest sufc38 Posted June 16, 2005 Report Posted June 16, 2005 Hi, Can anyone tell me if an air mass meter is the same thing as a MAF sensor?? Mike Quote
paulmpaciorek Posted June 16, 2005 Report Posted June 16, 2005 Hi Mike I know yours is a petrol but the purpose of the Maf or Air mass flow meter is explained here, http://volkswagen.msk.ru/engine/tdi-tech.pdf but correct me if Im wrong fellow forum members but it has the same "limited life span,problematic" purpose on both petrol and diesel engines. Paul. ;) Quote
Guest FlyingDutchMan Posted June 16, 2005 Report Posted June 16, 2005 Paul, That was a very interesting attachment. Thanks for that. FDM Quote
paulmpaciorek Posted June 16, 2005 Report Posted June 16, 2005 Paul, That was a very interesting attachment. Thanks for that. Credit for that attachment goes to Masked Marauder who posted it first.......very interesting as you said. ;) Paul Quote
Guest sufc38 Posted June 17, 2005 Report Posted June 17, 2005 Hi Paul, Thanks for that. I went into German & Swedish in Trafford Park Manchester today and the guy in there was really helpful. Not only is the air mass meter the same thing as the MAF sensor but he can sell me just the sensor probe for Quote
paulmpaciorek Posted June 17, 2005 Report Posted June 17, 2005 Hey It makes sense just to replace the probe rather than the whole unit as this is what is at fault.......in this day and age of recycling blah blah blah....respect to the people who are prepared to sell you just the actual part you need. Paul ;) Quote

seatkid Posted June 18, 2005 Report Posted June 18, 2005 All you need now is the correct size security torx screwdriver......doh! :o Quote
Guest sufc38 Posted June 19, 2005 Report Posted June 19, 2005 Well I guess I'll just have to raid the Laser tool stand at work for that then. Cheers Mike Quote
Guest sufc38 Posted July 14, 2005 Report Posted July 14, 2005 Hi, The probe that German and Swedish were going to supply is now apparently not the correct part. I don't suppose anyone has got Vag com in the Stockport area and wouldn't mind giving me a hand by reading the error codes before I launch into the expense of MAF sensor, Cam sensor, etc, and I'm still not entireley sure my gearbox is a bit suss. Cheers Mike Quote

Guest stormchaser Posted July 14, 2005 Report Posted July 14, 2005 A faulty MAF sensor will not be picked up by the diagnostics as the electronics part of the sensor still works while the actual sensor does not. The result is that as far as the ECU is concerned the MAF is working but the data it is sending is incorrect. I suspect that running a petrol Gal with a faulty MAF sensor could lead to problems with pitted or burnt valves as the engine runs very lean. If your suffering from a lack of power or an auto box that dosn't seem to want to kick down it's also worth checking the throttle cable. There is a position sensor on the accelerator pedal, if the cable is too slack then the ECU thinks the throttle is open more than it actually is. If it's really slack/stretched then you won't get full throttle at all and the car will feel gutless. Quote
Guest RustySkip Posted July 14, 2005 Report Posted July 14, 2005 I've searched (and read! ) just about all of the posts on this topic (having had the same symptoms and at a loss as to what was wrong) but the fault that I found was different (and much cheaper to repair). I've seen one mention of it on here and that is the blummin' vacuum tube from a solenoid attached to the bulkhead behind the heat deflector (...yeah the one that skins your knuckles trying to get it off). The other end connects to what looks to be a diaphragm that operates the throttle butterfly. The tube rubs on something, goes very thin and eventually wears through. The symptoms are exactly the same as MAF fail but you can force it to fail (i.e. floor the accelerator at about 50 and cause it to pull lots of vac.) If you treat the throttle gently, you can normally get by and it won't fail (normally indicated by fuel consumptionometer going below 30mpg) A piece of vac tube cost me Quote
paulmpaciorek Posted July 14, 2005 Report Posted July 14, 2005 Rusty What year is your Gal and which engine variant....90...110 ...115...130...BHP ?? Quote

paulmpaciorek Posted July 14, 2005 Report Posted July 14, 2005 Got a new MAF for mine...fitting it tomorrow....but I suspect this is not my problem.I think it may be a vacum hose somewhere or it may be linked to my ECT problem...as it seems to run worse when it gets hot....more so as its been in the middle to high 20 s here..Will report back after new MAF installed.....If MAF is not NAF...will sell it here for what I paid for it .

Guest sufc38 Posted July 14, 2005 Report Posted July 14, 2005 Hi guys, Would this vacum hose also affect a V6 engine, as my car definatley runs worse when it's hot?? Mike Quote
