Nice post, explains things very clearly.

I agree on the BOV "type" of noise, especially on backing off. What I have found is that with a pod setup, it's a lot louder, and is simply noise from the turbo inlet impeller itself. With an open pod housing, I can make the turbo make all sorts of noises back out the inlet, and in my opinion it's simply the turbo itself you are hearing. I've recently spent a lot of time ( and $$ ) on Erwin, and I haven't found any pressure regulation other than the vanes Gregoz points out. There is however a throttle flap "like" mechanism in the EGR inlet that both controls mixing of the recycled exhaust gas to lower the emissions, and to shut the engine down quickly without the typical diesel "run on" shudder. So it is a throttle of sorts.

Also at this stage the GT TDI is the only golf with a DPF, and the technology will be rolled out into forthcoming diesel models. It has been redesigned, in that it has a more distinct two stage format, to improve service life I figure. I read specs on the fact they will also all be common rail, but with the addition of some of the GT "hot-ups" lose no power from current with the 103kw still the same despite the "drop" back to common rail. Certainly be a lot quieter!

negative on that.

Well I still have the spare key from it and it came with a set DPF instructions.

I must admit I didn't have it long enough to learn about all the features differences etc.

I have some photos of under the bonnet, will check them when I get home from work

Ok. So here is a photo of the key that came with my first car.

DPF Key

and here is under the bonnet

Engine 1

Engine 2

because the motor has been pushed back it might not be visible.

Just not sure why VW would give me a DPF key and not have it on the car?

id guess they gave you the little tag because the salesman probably thought there is a dpf in there lol. fortunately for non gt owners, they dont have dpf's, whether they're 05 or 08 models. the dpf isnt visible (i dont think) from the top like that, especially with the engine cover on. it sits in the downpipe right after the turbo like a cancer.

ps no offence to those who like their dpf's

I am definately over it - feeling very free without it, glad the diagnosis was clear. No cancer in this baby
Took a while to convince me tho hey Mischa
