TBF, HDis do have fuel system issues... They are early generation 1 commonrail, so the LP/HP pumps do tend to wear out, the injectors wear also... But I'd say no more than other cars, it's just that PSA stuff tends to be "cheap runabout" category, therefore treated like shit, never serviced then moan when they start going wrong.
From my experience of PSA stuff, if it was serviced well and looked after, they won't cause any problems.
The engines themselves however are not weak, XUDs do get rod failures - but when you understand the forces involved, it's not hugely surprising that they do... Horsepower isn't directly relational to rod breakage, peak cylinder pressure is - and a 21:1 compression ratio doesn't help matters.
Also, anyone who says the 2.0TDi engine is reliable knows nothing about VAG TDis... I don't deal with VAG much and I know of: Snapped oil pump chains, cracked heads leaking water down the inlet, failing injectors, the 170 DPF is shit, failing turbos, flywheel failures.
