MAF issues
« on: June 28, 2004, 02:07:40 PM »
My CEL keeps coming on and telling me that my MAF is reading below the minimum limits. I removed my intake system and cleaned the MAF with electronic parts cleaner.  The reinstall and fired it up.  The first time I started the car, no light and it runs fine.  The next time I start the car, light comes on again.

I noticed this time the car chugged about three times on the initial move through first gear, but after that, no problems.  I drove the car all weekend and it drives just fine, but that light really irritates me. :evil:

So my question is this – Did I do a bad job of cleaning the MAF or do I have a leak in my vacuum system?

I am running the following mods that affect the engine:

Cold Air Intake – Clean and freshly oiled (I am very cautious about the amount of oil on the filter)
REVO software upgrade – peak boots of 20, holding at 15-16 in 4th and 5th.

I have the stock lines and DV in my car – I am planning on swapping the lines and DV soon – but I have had no problems with the OE lines or DV.  The boost is still strong and I do not see the gauge bouncing or have erratic RPM’s

So what is the deal?? :mad:

Check out those lines and the clamps for the DV.  However, it is probably justa  bad MAF. Soemtimes they can be cleaned, sometimes they cant.  Also, make sure it is plugged in okay.  When I cleaned mine on the Passat before I sold it, I didn't have it plugged in correctly and I received that error.

I would say go down and get it replaced if it;s not the plug, but with a CAI I doubt the dealer is going to cover the MAF. I de believe since the campain started to replace the MAF VW/Audi now require you to go to the dealer to get it covered.  The reimbursement forms were only for those who had it replaced prior to the campaign.

If someone was willing, or has a spare maf, you coul maybe plug theirs in to see if there is a difference.

I am going to take the MAF appart tonight - remove the sensor from the housing - and give it another clean.  I will also inspect the lines and DV.  

If that does not solve the issues, I will have it looked at on Thursday when I take it in for my new seat.

I have a CAI with a cone filter.  Honestly it is a crappy MAF wire in the sensor.  I have cleaned it about 6 times and it does not help.

I am going to pull the switch with my ex-wife this weekend and try running her MAF in my car.  If it solves the problem I will be facing a moral dilemma...Do i switch them back or not???

So is it because you are modified that you are hesitant for the dealer to take care of this for you? Give Dave Bell a call at McDonald VW.

I have a cold air intake and that is why the dealer is not willing to help me out.  I have spoke n to Dave and he told me to put the stock box back in and bring the car back.  Unfortunately I do not have the box, so I am SOL.
