  • 2001 v. 2002 Jetta 1.8T differences?

    What are the differences between an 01 and 02 1.8T Jetta?

    I think the 2001 is the 150hp and the 2002 is the 180? anything else?

    no seriously yea the 150 vs 180hp 1.8t.. umm i think its the same engine code still but the 02 might be a awp instead of awd
    other than that thats all i can think of.. yea and k03 vs k03s

      I believe they have different turbos too but they both make the same HP when chipped.

        AWD -> AWP

        In-dash cassette/CD player became standard on all but GL models for '02.

        VW's "bumper-to-bumper" aka "craptastic" warranty now 4 years/50,000 mi. vs. 2/24,000.

        Thats it.

              KWP2000 protocol, good for faster data logging.
              Edit: for late 2002 anyways and all 2003+

                the 2001 was most likely AWW morons, not AWD

                  2000 and early 2001 - AWD 150HP
                  Late 2001 - AWW - Upgraded turbo and stuff 150HP
                  2002+ - AWP - Same hardware as AWW, upgraded programming 180 HP

                  .... I think.

                    But an AWP ECU won't work in an AWW, so some of the sensors changed a bit too (yep, I tried it).

                    AWW and AWP has the variable cam timing (VCT) stuff (for emissions) whereas AWD's don't have VCT. AWD also has the k03 turbo (although a slightly larger downpipe than AWW).

                      I think there was a change in compression from one engine to the other too? Either AWD or AWW I think was 9.3:1 and it went to 9.5:1? I can't remember...

                        AWD and AWP had 9.5:1 compression, AWW had 9.3:1
                        AWD and AWP had 55mm downpipes, AWW had 50mm downpipes

                          First year of the exhaust cutout rear valence for the 1.8Ts and Vrs - not sure about the TDI. 2.0 still got the point-down hidden exhaust.

                          Were the dash cupholders revised in 02 or 01? Rear cupholders deleted in 02.

                          Side markers went from crystal to clear as well did they not?
