In reply to Si Withington:
Be very wary of the Peugeot 1.6Hdi engine, which suffers from similar turbo failure issues in all its applications - Ford, Volvo, Mazda as well as Citroen-Peugeot. It appears to be highly intolerant of poor or incorrect servicing and problems quickly arise if poor quality or incorrect grade engine oil has been used or if preventative maintenance hasn't been carried out during servicing. Not so much an issue if buying new perhaps, but unfortunately, when buying a used vehicle, a FSH, even a main dealer FSH, is no guarantee that the engine's been serviced in such a way as to avoid premature turbo failure.
No modern diesel engine from any manufacturer is free of issues as manufacturers try and squeeze more economy from highly tuned (and consequently highly stressed) small capacity engines while on the other hand aiming for much reduced emissions. All modern diesel engines are inherently reliable though; the weak points are typically not the engine but the ancilliary parts - belts, tensioners, turbos, high pressure injectors, oil pumps let alone DMFs and DPFs. At the end of the day, it's simply a case of weighting up the pros and cons and going for what seems to be the best case option. Don't overlook van forum chatter - often more educational and illuminating than you'd think.
No such issues with the Renault 1.5Dci engine though. Sites like Honest John speak well of the performance, reliability and economy of this small diesel engine, which incidentally is also fitted to some Nissan and Mercedes vehicles.
I too would suggest you also take a look at a Caddy. I've been passengered in a LWB version quite a bit - and have come away with very favourable impressions.
