MAF hell

[iancooney]

So i bought my new MAF from Vagparts a few weeks ago and installed it in 5 mins, and it solved my probalem straight away - smooth acceleration.

But now the chug at 2500 rpm has started again - with a ****** brand new MAF installed as well!

Whats going on???!!

This happened to anyone else? Or could it be something else?

Try disconnecting the MAF plug and run your car without the MAF plugged in... how does it work now?

If it's smooth - then the MAF has gone again.
If the problem still exists, then it's not the MAF.

Are you using an induction kit?

If you are get rid of it. This can kill your MAF. Most of them are lightly oiled and that's a no no!

If not, the part will be covered by VAG warranty.

I would also get down to the dealers for a diagnostics check. Friend of mine on this forum, BigSimon, nad the same problem and it was caused by a faulty brake sensor or something like that. So it may not have been a MAF problem in the first place.

Brand new induction kits will have a very light and even coating of oil. Problems arise when people re-oil them and use far too much oil.

I have been running a Neuspeed P-Flo induction kit for months which uses a K&N element and have had no problems. UK225 (a TT owner) has used the P-Flo for a lot longer and has had no problems.

The K&N panel filter is oiled, I've used that also and I experienced no problems with that either.

This AMM failure issue caused by oil coated air filters is very suspect IMO! I'm sure there was an article some time ago saying that this theory had been tested and no link was formed between failures of AMM and these type of filters!

I can't remember who wrote the article but it was from one of the main stream tuners.

Anyone remember this?

Considering a AMM will fail if you even look at it the wrong way also backs up their theory!

Probably worth findind someone with Vagcom in your area and running a few tests. Either this or take it into audi or a specialist and let them diagnose the fault.
