I currently have a 2.4 lump and I have to say apart from sounding exactly the same as a transit van i think its brilliant. I travel motorway miles in the day and its averageing 29.75 mpg according to my phone app. thats travelling at 65-70 mph all the way with 265/75 BFG ATs on, plus it barely even drops when towing. I took a my caravan on a 120 mile round trip, and still got nearly 300 miles to 65 quid full tank ( usually get about 340 normal driving)
Power its brilliant, will knock spots off a TD5 (that I used to own) and thats in standard tune, my TD5 had been tuned a bit. overtaking is much quicker and safer, and if you really want to be a boy racer, it will embarrass most cars off the line! surpises people!
Reliability- no issues yet, although I think the EGR could give a problem in the near future, but by then itll be close to the end of warranty and it will be ditched in favour of a blanking plate anyway, more trouble than theyre worth!
Anti stall feature is probably the best bit, makes pulling off with a heavy trailer effortless and hill starts simple, dont even need the handbrake any more (which is good because theyve moved it a bit to move the transfer lever and its a bit of a pain to get to now anyway!)
Although I do agree with the maintenance side, i dont fancy working on this engine for a good while yet, it doesnt look anywhere near as simple as my 200tdi is, but such is the times!
