Picking up on this a little late, I know...
I bought a 2.2 CDTi tourer in March this year. 05 plate, and 110k. Despite what I thought was thorough research before buying the car, the only information I found on line suggested how reliable they are! I didn't pick up on the timing chain faults until after I had bought it and found this forum. By which time I had realised my car had a dreadful noise coming from the timing chain area, which I thought (or perhaps with hindsight, hoped!) was either the alternator bearings or one of the pulleys. My huge school boy error was to NOT listen to the engine from outside when I was looking at the car! If I'd done that I wouldn't have bought it, but it drove fine and the noise couldn't be heard inside!
Expensive lesson, because 5 months later the engine cut out - yep, the chain had failed, effectively making the car economically unviable, since it needed a clutch and DMF anyway.
I replaced it with a 54 plate 2.0 i-vtec tourer the same spec (Executive). It's a more pleasant car to drive, and in better condition over all, so setting ***ide the expense of buying it, I have ended up better off in the long term. I personally won't touch another diesel of any description, being in the market for older, higher mileage cars, there are too many things that can go wrong and throw four figure sums at you.
I will admit, I miss the torque of the diesel, but at least I can sleep at night.
