richaber Posted November 25, 2006 Report Posted November 25, 2006 Ok So I tried running the car with the MAF unplugged. It ran just as poorly (ie no power) but did a little rev when it started. So back home I plugged the MAF back in and started it again, it did the little rev again, but now after standing a while it starts as normal. So, have I messed it up by runnig it with no MAF? And... if id did fit a new MAF would it need VAGcom or similar to reset anything?? Thanks. Quote
mumof4 Posted November 25, 2006 Report Posted November 25, 2006 running a car with a MAF unplugged wont mess anything..i did for months before i got a new one..When i got a new one i just fitted it..plugged it in and nothing else..worked a dream. Quote

The only thing that is bothering me at the mo is that it is a Pierburg MAF, TDIFAQ says these are really reliable. Has anyone changed a Pierburg MAF or have all the faulty ones on here been Bosch? All the pics on here are of the Bosch unit I think.Just wondering.... Quote

The only thing that is bothering me at the mo is that it is a Pierburg MAF, TDIFAQ says these are really reliable. are these 'hot wire type' or the 'thick film type' from what I understand hot wire get dirty and can be cleaned carefully but the thick film type deteriorate over time. MAF problems are notoriously difficult to detect byt reading fault codes unless its a complete failure :D Quote

MAF problems are notoriously difficult to detect byt reading fault codes unless its a complete failure :D sheesh... i did find a data sheet on the maf but it was all in german... so not sure if it's wire or film. there is one on ebay at the mo with the pierburg part number, am tempted.found this now http://www.msi-motor-service.com/ximages/P...0079_EN_WEB.pdf Quote
mumof4 Posted November 26, 2006 Report Posted November 26, 2006 the one i bought off ebay was a genuine bosch one...i saw the pierberg ones but went for a replacement that was the same as the one that was naffed.....i never had codes read in regards to the maf..could tell it was naffed as the gal had no guts..struggled to get up to 70 and was a snail on hills.. Once i replaced the maf..she was a dream to drive....she flies now and i love it :D Quote

richaber Posted November 28, 2006 Author Report Posted November 28, 2006 Thanks guys n gals. I have bought the new one from my local VW dealership. It is the Pierburg not a Bosch and this particular one is not a service exchange item. Quote

richaber Posted November 28, 2006 Author Report Posted November 28, 2006 start simple and work up..check fuses..check all vacuum hoses...check relays....etcc... aaah the voice of reason mum i've just been looking at the vacuum hoses, some are chafing, the one from the right hand pressure hose and the one going to the EGR ( ithink) is a bit crumbly, are these critical?
