Well that's not inspiring. Do we think the ACC range got a different bumper? I've had a lot of ACC vehicles and none of them have ever had the radar unit blocked by the bumper.

No the bumper is the same with or without the radar unit. My radar unit has gone faulty after working for 8 years.

How did you know? Codes?

Just check for faults and I have this. Any idea what this means?

Maybe re-check your CCF parameters. If you've enabled stop&go then try with that feature disabled.

Mine showed radar unit blocked shortly after every start-up which indicates that it isn't seeing a reflected beam. This could be caused if the unit is so misaligned that the reflected beam isn't seen, but it isn't misaligned, or that the transmitter or receiver has failed. I don't have access to a monitor for 77 GHz signals so I can't check if the transmitter is working, not that I'm likely to be able to repair it.

Tried both combinations unfortunately. I'm wondering if my vin is close enough to the older vin that it needs the ACC module in the trunk? It's BA35***

You acquired switch LR023197. My investigations revealed that the switch part number for BA349700+ the switch part number is LR029644. I don't know if that is due to a change in operation or just a superficial reason such as a new colour or style.

What prompted you to get that part number?

I actually ultimately ended up with switch LR057123 after lots of back and forth with Scudaria.
