    2006 Jetta TDI
    Volkswagen MK4 turbodiesel "how to" index
    For 2004-2005 Jetta TDI and 2004-2006 New beetle and Golf

    updated Sept 15, 2013

    This page is for mk4 Jetta, Golf, and New Beetle TDI 2004-2006. In 2005.5 the Jetta became a mk5 so see 1000q: mk5 Jetta DIY index if you're looking for the newer body style. In North America, the mk4 pumpe duse use the "BEW" TDI engine. 2003 and earlier 4th generation cars are not pumpe duse and use the "ALH" TDI engine. Review the main index page if that's what you have. Here are some more checks to see if you have a pumpe duse or not 1000q: cosmetic differences on Jetta and 1000q: injection pump vs. PD vs. common rail. If you have a 2004-2005 Passat, see 1000q: B5 Passat "how to" index.

    Did you just buy this car or are you looking to buy one? If so, see 1000q: mk4 TDI new car checklist to see a list of common service /problem areas, catch-up maintenance, and VW quirks.
