Well then...
Got the car done yesterday, took a couple of hours in total.
First the DPF was removed by the chaps at Elite Exhausts in Ayr (

They fabricated the replacement pipe while I waited and having seen them at work, when the car needs the rest of the exhaust replaced, that's where I'll be going. Start to finish 55 min and it looks like an OEM part.
Next the ecu remap to remove the EGR/DPF processes and massage the power delivery maps. Quick test drive and payment and then off home, in just over 2 hours.
The results- A very docile and drivable solution, with bags of power right through the rev range. It feels completely standard until provoked, when it goes like a scalded cat. Midrange acceleration is particularly impressive and much smoother than before. The car is also quieter overall, particularly from outside.
And now the purpose of it all- fuel consumption. Prior to the change it was showing an average of 16.1 l/100 miles, which equates to 28.3mpg, which compares with my calculated brim to brim average of 28.7 mpg. Now showing 12.5l/100 miles or 36.5 mpg. The technician advised that this will get better as the days pass and the ecu relearns my driving style- and I get past using the acceleration just as much!
I'll post again when I complete my first brim to brim in it's new configuration. If anyone wan't the contact details for the people I used for this, just PM me.
PS- Anyone want to buy a good, used DPF for a 2008 2.0D? One careful owner
