Location of MAP & Diode Mod

[02vwpwgn]

Can anyone advise where the location of the MAP is and how to access the wiring from the MAP on a 2002 Passat? I would like to try the diode mod.

Also if anyone has a chipped 1.8T and has installed the diode mod please comment on change in performance.


TIA

Re: Location of MAP & Diode Mod

As I remember, the "diode trick" does nothing for performance. Its a clamp on the MAP sensor which prevents the ecu from detecting too much boost when you are making max boost.
