Itsrainman, hi mate!
I have the same error as yours (P200200) and i was told to change the EGR cooler.. changed and the error is still there.. No power lose, but it happened after i went to a gas station and filled with "bad" fuel (even if it was diesel 55 and most expensive in my city), the next day i've got engine check light and 4 weeks can't get it done

)
I'm just sharing my experience with you, because i was told by the official dealer to change the EGR cooler and they were wrong. I have the same 14g in DPF.

Can i ask you please... do you still have this error (p200200) and check engine light on?

Error was reset after the change of both sensors and a forced DPF regen. I have only done about 10 miles since then so to be honest I have no idea if the fix is permanent.
I got the impression that because the sensors maybe faulty the actual DPF loading was being misread. The garage used parts from TPS so Audi parts and then recalibrate and then drive the car while monitoring the soot value until it stabilises and then run the DPF regen routine and again monitor the soot loading until it drops and stabilises. Fingers crossed. I had the older engine in my previous A6 and the EGR cooler was a lot easier to access than on the Ultra Engine. I’m a pretty competent mechanical engineer but just don’t fancy doing it on the drive over winter

. Getting a petrol car next time
