My daughter just purchased a 2001 Beetle and not long after, the check engine light came on. Got it checked at AutoZone and they said it was a bad MAF sensor. I saw on another website's forum that they purchased a MAF sensor for $52.00. Best I can find is $200.00 from AutoZone. Hoping someone on this forum might know where I can find one cheaper. That just seems like a lot of money. Thanks.

you can also clean them with spray cleaner

Thanks Hako!
I found one on 1stVWparts.com for $100.00.
Cheaper than anywhere else I could find.
