But particulate carbon isn't the only problem. Because of the hotter
combustion temperatures, diesels emit more NOx, which seems to be the
main point of issue ATM. I gather there may be catalytic NOx filters,
but the current fuss suggests they don't work very well.

Making a decision now is certainly difficult. We only manage 5-6,000
miles a year, minimum journey 10 miles, average 50 and, once a year,
500. All each way. I keep looking at the Dacia Duster, and have spoken
to as many drivers as possible, and have not yet found anyone with a bad
word to say about them, except that the diesel is preferable to the
petrol engine.

Very tempting, given the price.
