04's had hoards of problems (mainly comuter programming issues). It was the first time VW put 72 control modules in a vehicle. (TPM problems) mainly due to customers not knowing how to use the system!!! (OMG the TPM light is on and i dont know what to do, lets bring it to the dealer and have them add 5psi to my tires so the light will go off, or... OMH my TPM light is on and I added air and the light went off now its back on... omg maybe its because I have a nail in my tire) They did alot better off with the new jetta launch because they had 150 "reps" driving arround new jettas for 3 months prior to launch in order to catch all the "glitches" that may have occured.
