Is the specific maf sensor part number really important?

[kineticz]

Hey,
I am looking for a new maf sensor for my 1.8t. I've found loads of maf sensors for vag cars that have exact same fitting as the one I need, but a slightly different part number?

Surely if it fits then it will sense whatever air goes in no matter what the part number is?

Any advice appreciated

I read a post a while ago where the guy was having huge trouble with his car and it turned out it was because the last letter of the part number from his maf was the wrong one for his car.

I emailed vag-parts , they said they can check which one you need from your chassis number

I know the part number I need mate, just can't really afford the ~£60 for a sensor. The cheaper options I've found have similar part numbers and same fitting, just not the exact same part number I need

 

[rosscopecotrain]

maybe you could follow one of the guides on here and clean it ?

 

[kineticz]

I've tried cleaning it out with electrical cleaner, unfortunately didn't help

I removed the sensor then I just sprayed loads of the stuff inside then let it dry. Unless there is a more effective method?

Is that method GUARANTEED to work though? As I used spray with Isopropyl Alcohol and it didn't work. Maybe I didn't spray enough in?

Spend some time doing a search and you will discover loads of problems through not fitting the correct MAF / or fitting a cheap one.

Fit the correct Bosch Exchange item from dealer / ECP / GSF.

The correct one is must. I got an exchange Bosch one from ECP and it turned out to be the wrong one, made the car run worse than my original duff one

No, I've tried immersing MAFs in IPA before and as far as I can see, it makes *****r all difference. They are not a simple device.

 

[kineticz]

Exact part number it is then!

 

[Avant4me]

Exact Part No

AUQ/ARY/APP Engine (2001 onwards i believe) 06A 906461 LX

AJQ/APP ENGINE same but ending DX

Hope this helps, straight out of the VW parts guide.

Mine is a 2000 W reg so I presume it's AJQ engine then

Look on the front left corner of the engine block just where the edge of the engine cover is. You cant miss it as the corner of the block is ground off so it can be stamped. Failing this there will be a sticker in the spare wheel well.

 

[kineticz]

Thanks mate I'll check it out.

Anyone advise against running the car without the maf plugged in until I get a new one?

 

[DannyC87]

iirc running with it unplugged can cause overfuelling and damage the cat; not 100% on that though.

LCR maf sensor

Hi there,
Would a LCR maf sensor itself fit into my 1.8t Sport maf housing and work fine on my car?

Many thanks
Dan

 

[turbin]

probably not.... as far as I know MAF`s are type specific...

 

[DPJ]

No it wont.

I can't believe you asked this question after you posted this thread.
