I keep hearing about 'MAF'... But what is it & what does it do??

Its your air flow meter bud. Common failure on all VW's. So much so that VW now offer exchange items at a fifth of the price of the original parts. (Although they have never admitted to there being a problem!!!) [:D]

Wonder how many people have a problem with it but are totally unaware?!!

Quite a few I would imagine. Met one yesterday in fact. He was after a Revo trial but his car threw up about half a dozen fault codes so the dealer wouldn't do it. The dealer suggested spending a little money sorting the car out first but the guy just thought he was trying to pull a fast one and left.

MAF means Mass Air flow sensor. As it says it measure the mass or volume of air going into the engine by in this case a hot wire sensor. It does this by measuring the resistance of the electricallly heated wire as the resistance changes depending on the volume of air passing through it. [:D]

Does that cover it for you[?] [^]

Am I right in thinking that there are two potential problems with the MAF?

1. It gets dirty - cured by cleaning, which is a reasonable DIY job.

2. It gets goosed - which is a replacement job, cost around ?150.

Are either case covered by warranty?

So far, I am unaware of any problem with my 150PD at 33K miles. She'll still go like the proverbial, when asked, and the last half tank is showing 52.5 mpg, but that does include about 50 miles through pretty thick fog at 40'ish. Usually it's around 46.

Correct sometimes they can get dirty but i guess thats because u have a rubbish air filter. Or yes they get knackerd but the good news is that the stealers do exchange them for 70ish quid[:D]

Not a 'VW' problem, more of a 'BOSCH' problem that most manufacturors are having, just that you own a vw and hear about it on them.

Define 'rubbish' in this context. Do K&N filters cause a prob?

ok see wot you mean sorry for the non specific term[:eek:)] when i said "Rubbish" I meant an air filter that is not filtering the air correctly e.g an old air filter that lets particles through that a new one wouldn't and yes it could be a worn K+N that needs replacing.

Although they may say a K+N is for Life- its not a puppy[:D] lol
