yes been a failure for a few months now, though in practice the examiner will only look for the "can" and if present will pass it, most just have straight through "cans" now with the gubbins removed, same for CATS. Also most cars have undertrays which MOT testers wont touch, so you'll often get an "advisory" notice.

Fine if you go and get a re-map done to off-set

How would you do that? Retard injection timing? I'm sure no remaps do that...?

If I weren't towing a caravan occasionally I'd be looking for a petrol hybrid every time. Best of both worlds, and very reliable. Well the Toyota ones are at least.

39mpg out of a diesel? Is it broken??

Don't forget there are plenty of quick dervs out there these days - the 330d courtsey car I have did averaged 27 when driven enthusiastically. Best I managed was 46. Not bad given it had the same 0-60 as the E46 M3.

I think petrol cars are pretty unloved in this country because everyone is obsessed with CO2 and what they pay in VED. Even more so if it is petrol and a biggish engine. We picked our 330 up for buttons compared to the derv version...it does drink a bit of fuel round town but will return 30-odd on a run.

Straight 6 innit - more cylinders = more drag in the engine.

I've a 3ltr, V6 diesel A8. On a warm day I can get 50mpg, cruising on the M-way.

it's possible to an extent to chnage the mapping which will ultimately change the burn characteristics, if you do this post EGR/Cat/DPF replacement it could help, but not completely. It would however affect your MPG figures.

potential short service intervals.

Yeah those 18k services are a real pain.
