Hi.
A friend of mine have a VW passat 2001, TDI PD, not sure how big the engine is, but there is two red letters in the "TDI" on the back of the car.
My friend reports to me that the car is suddenly loosing power (at first I thougt it was going into limp mode, but I'm not sure about that anymore), and the power may return after some driving, after the next restart, or the next day. It does not sound like there is some connection between the return of the power, and a restart.
I have checked with my VAG-COM, and there is absolutely no fault code logged in the engine module (even if that's a bit strange I think).
I have testdrived the car for some hours, but the fault is not showing up at this time.
So my wild guess would be: the catalytic converter.
But is there anything else I should think of ? And is there any tests that I could run with VAG-COM to confirm (or not confirm) the catalytic converter ? Would the intake manifold pressure increase A LOT when the fault exists and we drive with the computer hooked up to the car ?
