Don't feel bad, I'm not either, I just pretend (usually foolishly)

It sounds like your ESP traction control was engaged that night with the wet roads the car sensed you slipping and beaked/ throtled down the engine.
Water getting into the engine is unlikely as the VW air box has a flap to take air from the engine bay if the intake tube gets clogged, so there would not be enough pressure to suck water in.
I have had ESP do some strange things in my GTI...
For the CEL chances are you have a dirty MAF, or possibly bad O2 sensor.
If you keep getting CEL you might want to buy a VAG-COM so you can scan the car yourself and save the dealer fee, you can get them off ebay for like $50... Its always fun to go to the dealer with the code and tell them whats wrong with the car![]()
I was working at an auto parts place and we offered a code reading service (but only for domestic cars.) So people would come in, get the codes, and then leave. Uhhh... the whole reason we offered the service was so people would buy the parts they needed to fix it... :huh:
A lot of places have the readers for imports, too. I used one at Parts America back when I had an MkIII GTI ('96).
It's probably the MAF (Mass Air Flow Sensor). Once you doused the MAF with water the ECU freaked out and threw a code and possibly even went into limp mode.
