Hello, got a 2001 beetle with a 2.0. Runs drives excellent. Cleaned maf. Checked for cracked hoses,cleaned throttle body.Reset code but P103 returns after 15 miles. If I unplug maf when car is running it will hesitate for a quick second then clears up. Should I replace maf?...what about coolant temp sensor?....any suggestions would be great.....Thanks

Here are some links; that should be helpful, when testing/troubleshooting the maf:

What kind of scanner do you have and can it see live data?

maf

If you cleaned the maf with a rag or something than it could have damaged it. From what I hear and read before that the maf sensor should never be touched at all just spray with maf cleaner then let dry. Did you remember to recalibrate maf/throttle valve after you finished? like this; turn key to on position without starting car, leave there for 25-30 seconds and turn back to off....YA DONE MAN:bigthumb:
