The most reliable Jettas were the A1 & A2's (pre '93), but they're getting pretty old & unreliable now. 1999.5 and up Jettas seem plauged with electrical problems, especially the higher end versions with the fancier electronics & VR6. The very common ignition coils, O2 sensor & mass air flow sensor problems have some VW extended warranty help (70K). But the rest of the common problems are your problem: throttle actuator valve & controler, stereo, body control computer (door locks & alarm), electronic dash & info center & very psychotic checkk engine lights. Watch out if you're in a strict emmission testing area. To add to this VW uses a very proprietary electronics system (OBD-II will only help you on some of the basics). They try to keep the repairs in the dealerships (which don't seem to want to help much & are expensive). I like VW's for the most part, but I'm sooooooo glad I didn't buy a new one in 2000. If you want to stay European in those years, try BMW & Mercedes, they aren't too expensive in the long run.
