This is just one of the ways to clean your MAF. I have a cold air intake so it's a little bit different removing the MAF, but the cleaning process is the same.

Things you will need:
Carb spray
Flat head screw driver
Adjustable wrench

First pop the hood and locate the MAF


Unclip the sensor by using a screw driver to press the button in and pulling the connector off.


Should look like this


If you have an aftermarket intake, use the flathead to unscrew the hose clamp.


Pull the intake off of the MAF, like so


Now you'll need an adjustable wrench to grab the hose clamp on the other side of the housing, slide it down toward the throttle body DO NOT REMOVE IT, it's a giant pain in the ass to get it back on if you do.


Wiggle the housing free and this is what you get


The sensor is inside the housing (obviously) so grab your carb spray and go at it



Let it dry before you reattach it. You're done.

Very nice, very nice. You'd probly get a more thorough clean if you took it out of its housing though.

Vice grips lol
You can use a hacksaw blade and some finesse to cut a grove in the top of the screw so you can use a flat head next time. I have tork bit sets but when I take one out I replace it with something more standard such as a phillips or a standard bolt or allen head.

I've got 2 sets of torx bits so I don't mind them, I just don't have the tamper proof ones.

Well its not even a standard torx bit IIRC, its a 6 point.. And yeah, tamper proof too. Theres a decent set on amazon for $15, nice to have if you work on other peoples cars.

And if you have one, a dremel with a cutting disk is easier than a hacksaw lol

For sure its alot easier if your hands are steady, but some people are not, and some do not have a dremel. Everyone should have a hacksaw. Besides that i got my torx bits from snapon for like 48 bucks, but it was a huge set with many different kinds. Including the tamperproof bits.

I would spend some $$ and buy some specific MAF sensor solvent, as it may be more chemical friendly to the other components such as the plastic and rubber.

I have not worked on the Jetta yet, but have used it on other cars and trucks.

IMHO it's not worth it to spend the extra coin for the specific cleaner, as carb spray or alcohol will do just as good. A lot of people just take the sensor out and toss it around in a bag/container of isopropyl alcohol for a few minutes then let it dry. I've done that method before as well but I didn't have any alcohol on hand so the carb spray worked for me.

This is my 4th time cleaning my MAF (hah) and everytime it has taken away my CEL except this time, looks like I'll be buying a new one!

You do know that if you by a new on that you can get one for a 2.0, its like 300% cheaper and the same thing just a different housing, you just buy the new sensor for a 2.0 and take it out of the housing and swap the new 2.0 sensor into the housing for your Vr. And save a few bills. Ya know towards your turbo...

Hold on....baby? Congrats, I have two of my own, Alexandria 8 and Joshua 5. Save all you can while you can, kids are more expensive than Ashley Olsens drug habits.




You can get it at any parts store or even walmart, just spray the stuff in on your MAF sensor and it will clean all the gunk out.

I can also tell you how to fix your cracked coil packs for under 5 bucks.

Yep, Chris gave us that handy info a while back. The VR6 MAF was over $200, f*ck that! The 2.0 is about a hundred bucks cheaper.

Oh all the baby is doing is delaying my plans... hardcore. BUT I still plan on either rebuilding this engine, or swapping in a 24v. It shouldn't be too much longer actually, I almost have my loan paid off [woo]

Thank you sir. JB WELD! My coilpack is covered in the stuff lol. Yeah Cory, you can get it at any automotive store, mine was pretty straight foreward and was only like 2 bucks if I remember.

You need to make sure the carb cleaner is safe for MAF sensor. Some carb cleaners can damage the sensor, carb cleaner and alchohol will dry out the plastic. I use "Deep Creep" its sensor safe and doesn't dry out plastic. Its basically an aerosol version of sea-foam - stuffs great.

These are actually called "Security Bits" - 6 pointed tamper proof torxy head - wtf - we just start making up stuff... You can ussually get the bits at good electronics stores (think about where you would buy parts to build a computer not Best Buy) and fastener suppliers. I live in a SMALL town in MS and I know 2 places I can get them here.

Yeah, everytime it took away the CEL until IT RUINED YOUR MAF. Buy the right stuff, your talking about a $5 difference to mantain a $200 component - no brainer

Well sir, figured it's not the maf at all, it's my O2 sensors. MAF is good and no CEL's unless it's below 30 degrees.
