Hello all
MAF, AFM whatever u wanna call it. The little box just next to the air filter with a black top and some dodgy little temper proof nut heads.
Anyone know what tool i need to buy to undo these. Ive heard its quite a specific vw tool but cant be that difficult can it? Ebay anyone?
Also has anyone used any other methods to undo these?
Any help would be great cheers
-
It's just a torx bit I seem to recall. Not VW specific at all, just used to annoy the motorist.
A Torx set is useful in anyones tool kit, so just grab on of these.
Cheers, Kae.

Hi..as Kae says' these fixings crop up in various places so a set of them is very handy. You can get a set of six i think, 3/8 drive sockets from halfords..there's a tiny wire in the MAF sensor so careful how you handle the thing.
Apparently cleaning the wire can make a difference to things if that's what you were going to do, i just sprayed mine with carb/fuel injection cleaner, didn't notice any difference myself.
-
Yeah thats the plan. Ive just changed and cleaned the breather pipes and throttle body. Still getting a slight power loss around 3000 rpm so im gonna give the maf a clean. Worked wonders on my last car but i had it done when it was in the garage so would be nice to do it myself this time.
I'll keep a look out for these torx sets

Disconnect it and take it for a spin, if it goes ok thats your problen.

my 8v has a dip in power about there too. seems to be just the way they are...
if you really want to get rid of it then get a remap. :grin:

so did mine. I had it RR'd at JKM in march and at 3000rpm it had a very very noticable dip in torque, you could feel it on the road pretty bad. Pipercross panel filter and new spark plugs and i cant feel the flatspot anymore.
-
i've just put in new plugs and leads etc... replaced air filter but just with a standard one. car is so much smoother after the service I did but there is still that flat spot...
I am tempted by the pipercross and drilled box... just can't quite bring myself to do it yet.
-
Well ive got chip to go in so yet more smoothness to come :smiley:
Aftermarket panel filter deff orecommended, + you dont have to buy a new one at the next service. Just wash it out.
Drilled airbox has 2 benefits, awesome sound and more airflow.
Also, a must, is cleaning the throttle body, could contribute to the flatspot. Mine is cleaned on a monthly basis.

How do you clean it? Do you just spray carb cleaner in?
-
Cheers all. I will try disconnecting it and see how it feels. It doesnt always happen and sometimes i think its fine when cold and only really happens when warm.
Have covered all the bases (filter/airbox/throttle body) Think i'll try disconnecting it for a short journey and see if that makes a difference.
-
Water temp sensor??
-
Mattyass: Your car sounds like its displaying the same symptoms mine had when I had issue with my MAF. Have you disconnected it yet and run it without? And if so, did it make a difference to your flat spot? Mine was undiagnosed for a while and I started losing noticable power at the top end as well. Car felt gutless...
Think I paid about £100 for a new Hitachi MAF on an exchange basis, but that was with a trade discount.

DO NOT, i say do not use carb cleaner on the very brittle maf sensor. this type of spray will destroy your maf and you will have to purchase a new one. always use MAF Safe cleaner like CRC. also do not touch the sensor with anything they break very easily. Also after cleaning the Throttle Body did you get your TB "realigned" via vagcom? OBDII Tb's need to be realigned before they will run correctly

Still not had chance to test it yet. How slow am i.
Was gonna use carb cleaner so im glad ive not rushed in. Are there any other alternatives to the spacific maf cleaner. Its not something i think will need doing often so cant really warrant buying a large can full
-
im not sure, but the can of spray is only 5 us dollars at any of our stateside autoparts store
-
whilst on the topic of air filters, what product do you use to clean it and how often. also ive seen filter oil for sale, is this worth the money or is there an alternative to use.
Its a K&N panel filter.

Ok so drove home with the maf unplugged tonoght and it was a dream. Ha! Definately more responsive and no misfire/lag around 3 grand. Time to get the sensor cleaned up. Steady hands mind
