PD or CR?

[pg_allen]

Hey hey
I drive a mk2 seat leon 2.0 TDI. Is there a simple way of telling if my engine is a PD or CR engine?
I looked at an article:
http://en.wikipedia.org/wiki/List_of_Volkswagen_Group_diesel_engines

This was not helpful because according to this article my car could fall into either PD or CR catagory.

The only difference i noticed between the two fuel injection types is Common Rail gives a better range of power and torque than Pumpe Duse.

Any help would be great

What year is your car or your engine code? From your Avatar it looks like an 06 plate right? That would mean its a PD engine, the Common Rail options only came out within the past 6-8 months (first with Audi A4 and then the Octavia vRS) but I don't think the CR option is available in the Leon FR yet.

afaik SEAT have never used common rail but its coming

Cool thanks for your help. It seems that PD will die off then? I believe VW make a 170ps CR engine so it would seem enevitable this would supersede the PD engine if the characteristics are better.

I don't know how accurate wikipedia is but they show a 200ps 2.0 TDI engine, i haven't seen or heard that used in any of the VW group.

It would be awesome if they brought out a 200ps 2.0 TDI Leon, we could keep up with the BMW's then!!!

The PD system uses individual injector pumps driven off the camshaft - great injection pressures and produce very torquey engines, but ultimately means the fuel injection times are limited to when the pressure is built up by the camshaft.
To meet more and more stringent emissions targets, manufacturers are having to do more clever tricks with injection timing etc, which can't be done with PDs. With common rail, fuel is constantly available at pressure and can be injected at any time.

That's my understanding anyway, happy to be corrected if wrong
