Just checked that link and it was posted in April 2021. Would there have been further updates since then?Having similar problems with the Adblue system in my 2016 T6. Had the software upgrade last week - so far so good.
You need VCDS to verify the current software version.
Got the advice from Ross Tech Forum
"...Most likely nothing wrong with the sensor.There is an ECU software update available which cures this issue + quite a few others. The ECU SW 04L 906 056 KE H02 3772 would upgrade to 04L 906 056 KE H02 6169 "
Anyone know what it is / was / should be?
Cant get mine looked at until 27th of this month and thats at the camper van suppliers not a VW agent.
