02 gti cel light malfunction

[CAMAROJV123]

So i put a short ram cold air on the gti like a week ago.
no problems

yesterday like 8:30 the check engine light goes on.

So i go home, switch the stock airbox back on, unplug the battery terminals and the next morning its off

What caused it to go on? the MAF was connected the entire tire and there was a breather on the end of the recycle line

you were warned:

.... and there goes your MAF sensor. You can't use oiled air filters. The oil distroys the maf. Expect a cel within two weeks.

The noise is the dirverter valve or n75 valve. Both are normal.

ouch

[-stew-]

maybe it's your thermostat.

vw's don't take too kindly to ricer mods. Buy the good stuff, neuspeed, abt, ect. or leave it stock.

lol. I called it. Told you so.

Your maf sensor is dirty. Put your stock air box back on. Take apart your maf and clean it with maf cleaner. You are going to need some special screw driver bits to remove the maf, so get those ahead of time. The ecu heavly uses the maf sensor, so you should really check it out with a vag-com. 180g/s at WOT is correct.

yea i cleaned it, and borrowed those hollow center star bits to get it off, cleaned it out and now its fine. thanks man. lol

[Yeehaw]

yea i put a filter and aftermarket 73mm MAF on my thunderbird and the check engine light was always on BUT the motor loved it hehe

[CAMAROJV123]

ik, the turbo could actually breathe! i took all the stuff back, ill prolly just get a neuspeed kit for it eventually when i have a small fortune to spend

I wouldn't even get an intake. It does absolutly nothing on the 1.8t. There is a great ebay knock off down pipe for your engine that adds 12hp for $100. Otherwise, save up and get a chip (40hp for $500). Hope this helps.

[CAMAROJV123]

[xxtremeteam]

[BoosTT]

Autozone has maf cleaner. It's even called maf cleaner.

[CAMAROJV123]

ooh alright its cool if he sold it. yea man i cleaned it off with that stuff, and its all good. thanks for the help, it was much needed haha
