Hi Guys,

My '01 TT has been throwing a P0300 code, but I now have a 0028 too.

Can someone please chime in and let me know if cleaning it has had positive results for you? I was thinking of giving this a shot first opposed to replacing. I have used CRC before with good results on other things. Thanks.

 

They make special spray for cleaning MAF but I would replace with new. I have cleaned them and they improve but they usually act up again fairly quickly.

 

That's what I was told by someone else, it sounds like a short-term solution. Thanks for the confirmation, I will just replace it. I just hope it takes care of these codes.

 

When was the last time you did plugs and coils? Is the car tuned?

 

0028 is bank 2 high lift I think. check your retaining bracket on the solenoid between cylinder 4 and 5 coils.

 

My car has close to 18k on it, the plugs and coils are original. Not tuned. Do you not think the MAF is the culprit? I might hold off for right now or try cleaning it so see if this clears the codes temporarily. Thanks Tim.

 

I do not believe your maf is the culprit. Even if your car has 18k miles it is still 13 years old.. parts do fail. I just take out coils on a 05 turbo S with 27k, all 6 where cracked!

 

it's been years but had maf prob , cleaned it and all was fine for 500 og 600 miles then it went bad again . put a new one in a few years ago and all is fine it's an 01 also.

 

cleaning mafs is a stopgap fools game on these cars. get a new one. i am still doing penance for suggesting in here ad nauseum ( when i was young and foolish ) that the cheap knockoffs were ok to use. they suck.

Make sure you discount the battery when you clean or replace the maf. This will allow the computer to adapt.

 

Thanks Pat, I will make sure to do this.
