Hi,
Just got my MAF replaced.
The old one must have been really knackered - must have died slowly as the power decline has been gradual, so gradual I didn't notice it.

But now with a new one, I can't stop grinning. It picks up speed so easy, it's like a new car.

Most definately happy.
;-)

Did mine a couple of weeks ago and best thing I ever did. No warning lights or running shite anymore. I wouldnt say I have experienced that grin factor like you have and like I was expecting, but it definately pulls better and smoother now.

How much does a MAF cost? did you fit it yourself or by a garage? if you fitted it yourself, do you have instructions? or if you got it doen by the garage, how much were the part/labour?

Thanks

Cost is around ?70 from dealer on an exchange basis, although someone said you don't need to give the old one back now. Fitting is a doddle if you have the security torx bit. Have a look in the how to section ct.p (I think) did a great write up on cleaning the MAF and it will show you how to remove it. 5 minute job so don't waste your money having it fitted.

?70 - ?80 is a good guide (plus VAT and surcharge)

When I bought mine about a month ago there was a ?20 surcharge for the return of the old unit if bought from a dealer.

I would also strongly recommend paying a few quid extra and getting a genuine one from the dealer. I have heard many a horror story about inocrrect and faulty non gen units off tinternet. Plus you have the hassle of posting them back etc if they do fail. In my opinion they are a delicate unit and should never be posted as they are easily damaged by vibration. You also get a years warranty on a VW one.

It really is a very easy job. There are plenty of good guides, but the best bit of advice I can offer is get a jubilee clip in advance that will clamp at 70mm. The old clip will be a pig to get back on unless you have the proper pliers. Otherwise all you need is a phillips screwdriver. (V5 BTW may be different on other models but I doubt it)

My car only has 62K.
It does mostly town driving, short journeys.
I am not sure if that would kill the MAF early.

It cost me 60quid - parts only, no fitting charge.
The mechanic is a VAG specialist and was doing other work (front bushes).
I asked him to check it out as it felt a bit dead to me.

He was nearly laughing at me after he test drove it - couldn't believe I'd been driving it like that.

After he replaced it I couldn't believe the difference.

Still smiling!

The impression I get is that the extremes between running well and bad are much greater on turbo'd cars, be they petrol or diesel?

Aye, I think it makes more of a difference on the TDs.

Is 60K/5yrs, typical lifespan for a MAF?

If your lucky I reckon. I have heard of cars with 20k on the clock suffering failure. I have also heard of some modified cars failing within weeks, probably due to either rock hard suspension, oiled induction kits and even the MAF not being secure and wobbling about with a cone on the end of them weighing them down?? Another factor may also be the fact that many non gen and frankly substandard MAFs are for sale...

I also think it is an inheritant problem with MAFs, be they Bosch or not, and not a problem confined to VWs. Rovers suffer problems with them, so do Vauxhalls and Volvos bigtime, so maybe its just one of those components that is classed as a consumable as they are quite fragile units?

Then again, I bet some people have never touched them after years and numerous miles. Maybe performance might be down that one might not notice, but if there are no warning lights or running problems then you would think all is OK wouldnt you?

I've always suspcted mine to be dodgy, but obviously I know no different!

Sometimes my car will pull like a train, other times its like im driving my 1.1 Fiesta again!

Can I take the MAF out and see if there is a diff, ie drive without it for a bit?

no mods mind.

but the new one is still going at 45k km, if it fails in 5 more i wont be pleased.

You could always remove the multiplug on the side and take it for a quick spin, see if there is a difference. Bear in mind it will just run on a factory MAP without the reading so you might not notice much. I would also not recommend driving very far with it off as you might poison your cat and or some sensors.

Its such a common problem that in all fairness isnt always obvious to spot and even with equipement test, but it could be the money well spent on a new one.

See thats strange. I never experienced that before and after wow factor. Def faster and runs better etc with the new one, but no 'huge' difference that I was expecting and everyone else seems to have [:'(]

No idea if it is a genuine part or not - probably not at that price.

It was not a stealers, just a VAG Specialist round the corner from where I live.

I still have the old one - it looks like new - no dirt or nothing on it.
