Peugeot XUD. So simple, yet economical, reliable, refined, easy to fix, fast enough.

but they don't make them no more, do they? :(

Wasn't this the one that put rods thru the block from time to time?

Batch of faulty con-rods out there; all turbos, mostly in 306's.
Engine closely derived from the XUD is still fitted to Berlingo/Partner 1.9 versions and probably some light commercials.

How long is a piece of string !!
Okay the BMW 3.0 diesel is superb as is the worlds most powerful automotive diesel, the V10 5 litre lump made by VaG.
However these are fantasy engines, as I think most people are looking at 1.6 - 2.0 diesels.
I think the BMW 2.0 diesel is externally the quietest, however I have been in a number of diesels which where externally quieter than my car (A4 1.9 130BHP), but were quite 'dieselly' internally at tickover and initial pull-away.
Notably the 2.2 Mercedes C class diesel, and Mondeo TDCi.
Some other newish diesels are not returning the 'promised' economy according to what I've heard/read, ie the supposedly ultra high-tec Honda 2.2 unit.
All round my money would be with the BMW for fuel consumption refinement and flexibility, especially as they seem to have overcome the serious fuel system problems that were known on BMW diesels a couple of years ago (recalls etc).

I have to disagree, I have done 100k in my Mondeo and it still idles in a very petrol like relaxed way where as most diesels including the 1.9 TDi's have a very urgent idle, a thrumming, 'hunting' type idle, also I have said before here that a neighbours Golf 2.0 TDI on less that 20k miles is much noiser on initial start up and on idle than the Mondeo. In my experience the only four cylinder of a similar size that compares is the 1.9 DCi Renault however I agree that the BMW is externally very quiet when warm.

I didn't say the Vag engine was quiet externally, what I said was that the engine noise was well subdued internally compared to some other diesels. Perahps I could have worded it better. I find funnily enough with my car there is hardly any difference in engine noise on a freezing cold start-up or when warm, it must have something to do with the way the Pumpe Duse system works. Also, unlike petrols, some diesels do 'mellow' hugely with a fair few miles on them, perhaps this is the case with your car.

I reckon it improved over the first 10k or so though has not changed much since.

Roly,
my TDI is much noisier when it's cold. Sounds more like the John Deere mentioned earlier! But it pulls like stink and has a magic, disappearing rear view mirror. Put your foot down and anything in the mirror disappears.

Just checked. No longer available in Berlingo Multispace, but apparently still there in Berlingo van

Agreed, I had the normally aspirated version in a Citroen BX and a turbo version in a Xantia.
Neither car was lacking in performance, although the Xantia was lightyears ahead of the BX in terms of overall package.
TD engine was extremely refined and economical even when compared against some current diesel units.
Still think the Xantia 1.9 TD was one of the best all round value packages ever, even the styling was good.
If you see one today they haven't dated badly at all.

My only experiences are with VW (1.( TDI) and PSA diesels but the VW ones tend to go like a rocket whereas the HDi in my 306 is more mellow. Still pulls well from 70 - 90 though.
I'd like a bit more poke, but not at the expense of ripping that damn dual mass flywheel apart. Chip plus intercooling would probably see 120 - 130bhp...

I'll second that.
The XUD was by far the best mass produced diesel of its kind, in its day.

Is it not the DW8 engine in Berlingos etc now?

Block, pistons, crank, big ends etc all carried over from the XUD series to the HDi. Only just replaced, with the new 1.6 HDi, which is all alloy (but I suspect, will look outwardly similar to the older engines). Just goes to show how well (over?) designed the bottom end was 20 years ago. Although there were quite a few engines that threw con rods (and it was shameful that PSA denied responsibility!) the % of total engines built was tiny. Cambelts that easily last 70,000 miles, with tensioners that last 200k. Properly treated they just go on and on (provided you change the head gasket every 100k or so..)

Is it illogical? It must be Citroen....

Do the head gaskets fail regularly after that sort of mileage?

Only on French cars;50k on a Peugeot!

What about economy? My 306 HDi, as an average over 18 months, has achieved 55 m.p.g. I'm impressed.

Your single experience is not statisically relevant, as I have been told many times when relating my experience of Citroens. As has been said earlier, the XUD is one of the most reliable diesels ever made and is noted for its longevity.
I was referring to the earlier comment on the need to replace the head gasket on XUD engines, at around 100K. I asked this, simply because ours is now past 100K
