It's been a while since I was last in the UK, and at that time I didn't own a Golf - now I've discovered this forum and people talk about a "MAF" - would someone be kind enough to tell what the h*** it is and how do you cook it? Everybody seems to know except me...

MAF Mass Air Flow sensor. HTH hopefully someone can fill you in on the rest.

A MAF is a mass air flow meter. Basically it measures the air getting
into your car and the oxygen so it can relay info back to the ecu. That
way the right air/fuel mixture can be delivered to the cylinders.

Thanks guys - I've been trying to twist my tongue around al sorts of possibilities! (All of them FAR from the mark) We DO NOT call it that here, needless to say.

Much obliged for the input - I'm only guessing but is this the thing that has a nasty tendency of getting clogged?

Where is the MAF? And is there any easy way to know if it's working ok? Is there a certain 'look' it should have?

 

[Wee Man]

I've heard you can clean MAFs to help boost performance. How's that done and where is the MAF situated?

 

[NikB]

This is what a maf looks like -

and this is where its located -

 

[ian32]

Thanks very much - when I looked I knew I'd found the right bit - the hand was still attached... (PM if you've lost one recently)

Great pics NikB! Now how do you take it out and what can it be cleaned with?!! []

There should be 4 screws to remove the whole unit after removing the hose. should be able to unclip a cable from behind the sensor then just spray the sensor and sorrounding parts with electrical contact cleaner (bout 3 quid from halfords). My Idle Revs were fluctuating badly until i cleaned the maf, didnt see the really dramatic results i was told to expect though [] but did help. Also would recommend the 20k booster from halfords (bout 20 quid) just spray the whole can through the inlet manifold while revving the car... experienced a lot of smoke billowing out exhaust when i drove it again but turned out to be part of the cleaning apparently []...restored a fair amount of power.... all worth trying for the hell of it..... []

Have fun []

 

[benjie]

cheers for that, I don't know if mine's faulty or anything, but with
the number of posts on here about hassle related to MAF's I think it's
a good idea to keep mine looked after!

(Wish I could say that for the interior - it's a state!!)

Be glad you found this place now, rather than this auction later! -

Cheeky sod, but you can't blame him for trying!!

 

[liquidshokk]

Damn! coulda made some money then!!!!!! [][][]

Fantastic photos, you will now have many enthusiasts cleaning their MAF's. I had no idea where to find , or even knew one existed. I'm going to give mine a right good going over , see if cures problem . Let U know.

BRILLIANT SITE , I've just found out about it.

Cheers

another way to recoup some performance from your maf is to apply electrical contact grease to the connector that relays the signals to the ecu.

the grease is quite expensive as it is a special grease that helps conduct electricity and prevent corrosion of the terminals. simply pull the plug off and liberally apply it to both male and female connectors (gold plated ones) and put the plug back in.

this should cure any flatspots you have throught the rev range which were caused by a dodgy connection due to corrosion of the terminals or build up of dirt/moisture over time.

grease can be bought from places like RS or maplins.

it worked wonders on my V5!

thats ?4.99 please []

 

[nudda]

Sounds good ! I think Ill give me V5 a looking over too

p.s: cheques in the post []

I had a look round halfords but couldnt find it whats the booster called please ???????

 

[liquidshokk]

yeah its literally called 20k booster, it comes in a long blackl box but its a pretty large spraycan inside, should be near all the engine additive stuff (thats where it was in southampton!) Let me know if you need any more info

Cheers []
