I have similar problem. I found that there was such option in STG 01 (Engine Control unit) -> basic settings-> adaptation of dpf filter pressure sensor, but i assume that it was in older version of app and in current app it's gone (missing). Can anyone confirm this?
in current app i can find only low-pressure egr differential pressure sensor adaptation but it's not that one i need.

I'm not sure if I'm deducing correctly but... I've found service workshop manual for CUAA engine.
There in chapter Removing and installing pressure differential sender -G505- there is only physical disassembly and assembly.
As a difference, in other chapter i.e. for removing and installing fuel pressure regulating valve N276 there is step "Following renewal, reset lernt values -> Vehicle diagnostic tester -> 0001 Engine electronics functions -> 0001 Reset adaptation values of engine ctrl. module -> Reset lernt values of dosing unit and pressure regulating valve.
Does it means that for pressure differential sender G505 there is no need to make any adaptation or removing lernt values?
p.s. I have a DPF pressure sensor error. I made mistake and replaced the wrong sensor (not DPF but exhaust gas ;-) ). I've ordered a new one to replace the broken DPF press sensor. When I replace it after the weekend I will write if the error disappeared without adaptation.

Hi Issac, i have the same P154B00 with my Tiguan currently. I have ordered a replacement DPF Pressure sensor as it looks a simple enough task to replace it myself.. but wanted to query if you did need to do anything after replacement or the Engine Management light never returned after clearing the error with OBDEleven?
