Hello everyone!
A couple of weeks ago, my Audi Q5 V6 TDI 2010 went into limp mode when pulling a trailer up a steep hill. Most of the power was gone, and we had to pull over numerous times to let the traffic pass. A local garage identified the famous P2002 and warned me about significant cost of repair. After some thinking, I bought VCDS and I haven't regretted a second! After hours with analyzing, googling and youtubing, I suspected the Differential Pressure Sensor, at one time I logged P2453 which also pointed me in that direction. After I had installed a new sensor, the MILs were gone and I took her (the car) for a spin. I wanted to push her up a steep hill, but I aborted due to heavy rain. The car seemed like the good old days with lots of power, but my test trip was too short I think. After the trip I ran a new scan and found no new DTCs, fortunately. I did no adaptation of the new pressure sensor, and I didn't reset any learned values of the differential pressure sensor (IDE00468). I might be a pussy because I didn't dare, but the car seemed OK...
So - my question is - is it necessary to do any adaptation of the new pressure sensor, or reset the learnings? Is there any risk involved by doing that? I have measured some key values given below (perhaps too few?), I will really appreciate some comments on these. The measurements were done with ignition on, engine off.
Kind regards,
Paal.

IDE00427 Particle filter: difference pressure 1 hPa
IDE00428 DPF: offset for differential pressure -1 hPa
IDE00432 Particle filter: time since last regeneration 8335 s
IDE00433 Particle filter: oil ash volume 0.19 l
IDE00434 Particle filter: soot mass calculated 9.64 g
IDE00435 Particle filter: soot mass measured 11.46 g
Here are approx. the same measurements, taken eight days before I installed the new sensor. The car had not been on the road between these readings (except for the short test trip). It also might be worth to mention that this car is running on long trips 90% of the time, it's on short trips only occasionally.
