Diesel Touareg Test drive

[5STM5]

I have never owned a diesel vehicle, but took a 2007 2.5 TDi Touareg for a test drive today. It felt really rough until the engine warmed up, but even after that wasn't really a smooth drive. Is this what to expect in a VW diesel, or could there be a problem with the car?
Just to clarify, when I say rough, it was a small vibration felt in the car, but also the engine noise was loud inside the car.
The car is a 2007 65K miles vehicle.

The 2.5tdi is an awful engine in the toureg, drive the 3.0tdi, it's much much better!

This 100%. The 3.0 is leagues ahead of the 2.5 5 cylinder unit.

I didn't realise the Touareg had a 5 cylinder diesel.

So it's not the 2.5 TDi V6 that you find in so many Audis then?

It's an in-line 5 cylinder. I think at some point they were badged R5.

I think it's essentially half the V10 TDi unit.

Or all of the engine from one of the VW commercial vehicles, so I gather (this may be made up but it certainly has the NVH characteristics of one!)

There's two different 2.5TDIs that I can think of,

The v6 that was fitted to older A4s, Allroads and the like.
The 5-pot that was fitted to T4 vans.

Neither is a stellar choice, the 3.0 v6 is in a completely different league.

Yep,the five pot from the t4 was fitted to our Touareg,20 odd thousand miles of going somewhere in it and coming home without it,something was chewing crank sensors up,they kept replacing them it kept breaking down.
They refused to accept that there was something wrong until the 6th,yes sixth sensors failed. FFS!
It turned out that it had picked up a strip of the sump baffle and this had wrapped,forced and bashed its self round the lower end of number one rod and fecked the cylinder.
Not just me either,
I read this a day or so before ours went for its second sensor and showed it to the main dealer tech, who dismissed it:

The Highways Agency is testing one of these as a patrol car, VW have produced a special version to H.A. specifications. I'm not sure which size engine it has.
