At 125k your DPF's don't have much life left in them. So whilst you might pay £800 to replace these sensors, unfortunately you might do this and then your DPF's are too far along to work properly.
Most DPF's give up around your mileage. Granted your V setup means less flows throught them but still.... I would gut and remove.

I've just had the DPF removed. She's sweet as a nut and at a fraction of the cost. Wouldn't hesitate to do it again on another A8 as I now know I've never got to worry about it again.
 I actually did the filter removal myself and just had the ECU reflashed. Easy peezy Bex

Just a quick outcome and hopefully my last post on this subject, after a lot of research into the potential issues and longevity with the DPFs on my car I decided to keep them! There doesn't seem to be any specific cases of failure on this engine so long as the car is services properly, but if there is then I will probably get them cleaned or replaced rather than removed because of the potential insurance issues of exhaust "modification" and required re-map.
I had both sensors replaced by a local independent VAG specialist and all seems to be back to normal. Total cost £290 in the end as I needed to get some exhaust clamps replaced too. If anyone is needing work in the Manchester area I can highly recommend VAGtechnik, they did a good job for a much more reasonable cost than any other dealer/garage I tried and didn't just make it up as they go along like the main dealers seemed to be doing!

That's a bit better than one and a half grand, but I bet you didn't get a tin of Audi travel sweets and a wash and vacuum sir!

for VAG Technik  Audi could learn a thing or two about customer service from some of their ex-mechanics who set up as independent specialists!!!!
