Adaptative Cruise Control not available

[JPM007]

Hi all

After driving through heavy rain this week on my 2017 Passat B8 1.6TDi the ACC not available came on the dashboard.
I looked at the radar sensor itself to find out that the washers around the adjusting screws are fully corroded and the sensor is loose.
I’ll need to get a replacement support and might have to re-adjust the radar sensor.
Looking around on the Web, it seems to be a pain and the dealers would be asking for several hundreds to do the realignment/adjustment.

OBD 11/VDS is a must have to do it and I don’t have neither (yet), I’m in Milton Keynes (UK) area.

Does anybody have experience to share on this or can assist me with OBD11/VCDS ?

Thanks
