lol welcome to the world of VW - go to www.vwvortex.com, and the forums there. lots of ranting and raving about MAF failures, window regulators, coilpacks, electrical gremlins, etc... granted, if your stealership is decent enough, you'll get everything kosher again. VWoA is pretty decent about "common" stuff - they nationally recognized the window regulator problems, and thus the new, sturdier parts....
my 99's been in the shop 8+ times for electrical CRAP, but its skraight now. (a mix of MAF failures and electrical gremlins)
im sure you luv your 337 though
still, wouldnt trade my dub fer nuffin - well, maybe that sexy Audi S4... yum....
