103kW and 125kW 2.0 TDi motors - quick question

[ABCD]

I have one of the earlier 2.0 TDi Comfortlines ie with the 103kW motors
I had always thought it did not have a Diesel Particulate Filter, mainly because I had noticed from day one that "diesel cloud" illuminated by car headlights in the rear view mirror when revving past about 3000rpm. I also reasoned that because there was no DPF (and hence more soot etc exiting the exhaust) the tailpipes from the rear muffler needed to be tucked under the rear apron of the car and directed downwards toward the road.

Anyway I was following a GT TDi the other day and as well as noticing the clean "soot free " twin chrome tailpipes I did not see any of the "diesel cloud" even when I was pretty sure the driver was giving it a bit of a hurry up accelerating away from a set of lights.
My question is whether the 125kW 2.0 TDi now has a DPF (and hence the reason it can get away with the chromed, rear facing tailpipes) or is it something about this 2.0 TDi motor that might explain it (ie higher compression ratio/bigger turbo = more efficient burning, less particulate matter)??
Cheers

The GT TDI has a DPF fitted along with a larger turbo and different injectors.

You got it in one, it's purely the DPF. I'd say all new VW diesels will have it fitted from here on out, as it's amazing to get that level of performance with no soot cloud. Clever bit of technology, unless you have a bad experience like Mischa.

The upside to yours is you have a free-er flowing exhaust, and not much less grunt on paper.

[Mischa]

mmm now think of all that smoke just sitting inside your exhaust clogging the whole system up and be thankful that you dont have one

i like leaving something behind (cloud of black soot) for people to remember as the little blue tdi disappears into the distance!

you say the 103 doesnt have a variable vane turbo when in does? the 103 has the vnt15 and the 125 has the vnt17 if im not mistaken

[Guy_H]

103 does not have the variable, the 125 does.

The 103 has a dual path (split for the pulses on the intake to the turbine)

Nope. The VNT15 is variable vane.

WRONG.!!!!
