Hi, did you get this sorted? I have the P2002 error code, so I had a DPF technician come out to do a clean and he said the the DPF was working fine, its doing a regeneration every 600 km and it had in fact just completed one the week he came out. He said the issue was the EGR cooler (his view) but also said it could just be a faulty sensor. The car runs fine, no issues with fuel economy, I keep the ad blue topped up, no issues with performance etc. The only other thing he said was the Ash build up was just under 40, but he said its normal for a car of my age. My car is a 2017 A5 and has done 109k miles.
