Checked by hand
[good]
A long-legged diesel, with the belt and fuel system on record
Worth buying, but only on the right car. Proof the timing belt and water pump have been changed, and a check that the CP4 high-pressure fuel pump hasn't shed metal into the fuel system.

Verdict
The timing belt is the critical item on this engine.
It fails occasionally, and if the records don't show a change, the car needs one straight away, so take the cost off the price. Oil pump wear or sludge is rare but just as critical, which is why regular oil changes matter. Injectors give trouble occasionally and intercoolers leak rarely, both cheaper to fix. Beyond that, the list of confirmed faults is short for a diesel of this age.
