#1 Question: Do I have a 12V VR6 or a 24V VR6 (For the US)? 12Vs have spark plug wires, 24Vs do not (they have individual coils).
In the US, all 24V VR6 MkIVs came with engine code BDF and the 6 speed manual 02M or 5-speed Tiptronic 09A transmissions (Jetta only). Eurovans with the 24V VR6 came with the 5-speed 02J or auto tranny.
