That number is not good for your car, I am just getting to use my work PC with Google Workspace so I can use ETKA but I have been off five weeks and there was a pile of updates which it is still doing. Using your VIN in Partslink 24 the flap unit on the EGR cooler is shown as 04B 131 501 D
Interesting, a VW dealer sending you a Partslink 24 screen shot instead of from ETKA, which they are not supposed to do anyway. The part you have fitted is correct for the car, I just feel it is the wrong end of the system.
Even not wearing your seat belt upsets the stop/start but that is no bad thing as it saves bugger all CO2 but destroys starters, flywheels, batteries and requires ridiculous complexity to the electrics such as failure prone LIN BUS digital alternators and the attendant battery control monitoring units which also fail, my workshop was going through this today.
