Had it checked today and It's the DAP getting clogged up apparently, some bloke called L666 KOP 
on here used to go on about Diesels doing this if you didn't take them on decent runs to clear them out. Never had this trouble in my last two BMW'S but this one obviously needs to be taken out a lot more than we have been doing, which has largely been short journeys.
Anything you can recommend to help prevent this Shane or anybody else?
It's been said Craig.
Regular decent runs to enable regeneration.
The concept is bollocks to be honest, just more technology forced upon us in the quest to get our emissions as low as possible.
China on the other hand get to build a power station every week.
Get yourself a proper old school diesel, no fancy filters, no sensors, you'll probably get 5/6 miles less to the gallon. But there'll be no bother whatsoever.
Alternitively, find a garage that will erase the DPF, and EGR from your ECU. The guy I used to look after my cars/vans would do the job for 500 quid. Economy, and performance would improve every time. Never any probs at MOT time.
Manufacturers don't help though, they're happy to sell you a city car with all the tech on it, and push the economy/emissions angle, yet the 'city' running that the cars do actually kill the car unless you take it for blasts up and down the motorway. So you actually need to emit emissions, to keep your emissions down ? Backwards thinking me thinks.
