Hi Guys

Fantastic forum, I’m having information overload here lol...

I was hoping I could gain some advice on an issue I am having with my 2013 A6 3.0 BiTdi.

I bought the 3.0 BiTdi around 18 months ago as an upgrade from an A6 2006 3.0 Quattro and I was amazed with the power 313 bhp. Anyway I have 122k up on the clock now as I do big miles with my work around 1k per week. I was traveling home last week on a 140 mile journey traveling along around 60 mph when I noticed the flashing glow plug then limp home mode after another 20 or so mile I notice the engine management light come on also. When I got home I plug in the Ross tech gear to try and clear the fault and I see there are 2 faults.

Fault 1 actuator module for turbocharger 1 pooaf 00032 stuck
Electronic damper Turbo 1 sticking - I solved this by replacing the electronic damper with a repair kit costing £252 ( Apparently I was lucky here as there are 2 models 1 that needs to replaced with the twin turbos removed and reprogrammed and the Hella version which mine was that can be replaced in the car with no reprogramming) Once we replaced this the fault cleared.

Fault 2 Diesel particle Filter P2463 00 (175) Excesive suit accumulation Mil On confirmed Fault Priority 2 UNSOLVED
I do a lot of miles as I said therefore regeneration should not be an issue unless with 122k on the clock the DPF has reached the end of its life. I have tried to force a regen with the rosstech gear but the message I get is that it cant be done for safety reasons. I have taken it for a couple of runs and on each of the 2 occasions after 20 mins at between 2500 -3000 revs switched engine off then back on the car ran perfect for a couple of mins then dropped back into limp home mode.

I have read quite a bit on this and I see a lot of people remove the DPF and remap however I realise this is not good for the environment / insurance reasons but does this cause an issue with the UK mot test yet? Also I would rather keep the car standar and fix the problem if possible. So can the DPF be cleaned out or does this just push the problem down the road?

Any help would be greatly appreciated as I want to get back on the road asap...
