SOS Flashing warning, away from home in Germany. Looking for a part number please.

Hi. Got the flashing symbol and managed to get a readout from VW garage in Belgium. Unfortunately not much other assistance offered. I’m looking at trying to get a fix done tomorrow Monday. Reluctant to start any removal as van is still driving ok. Unless I have the part in hand.

Just spent best part of an hour in a VW main dealer in Germany totally unable to identify the part required and won’t order in a part unless they have your address and UK isn’t registering on their systems. (Same in Belgium on Friday) The part number they assured was correct was for exhaust system not intake?
I put photos on Chat GPT and had part number in 10 minutes. With some questions and feedback.
Asked VW dealer where nearest motor factors was and part will be here tomorrow 0900.
First time with GPT but very impressed.

Found a Bosch dealer garage whilst on way. €50 to fit and clear fault code.
