T6-T6.1 facelift with ACC Radar

[Boyo72]

Hi all I have a T6 with T6.1 face lift done by previous owner with radar and just standard cruise control, not sure which radar is used though i would presume its still the T6 one.

My problem is that on occasion while passing other vehicles on duel carriageways or motorways and it appears to be the more taller vehicles i.e. trucks or really big 4x4s but it can be the odd car then something activates the brakes to stamp on then release with a symbol of a white car with like chevrons behind it flash up and its coloured white rather than amber or red.

When it happens it scares the crap out of you, I scanned the vehicle and no error messages.

Could this be that the radar just needs adjusting manually or settings changed in some software.

Also curious to know what are the settings that are mentioned on here i.e. dataset parameters and how are they changed can i do this with a aftermarket scanner.

It will need a recalibration from a specialist as it has moved position and the parameters will be altered. This should be done everytime a sensor mount has been touched or ride hight altered.

Perhaps a simple calibration will not be enough, since the radar is installed much higher!

Possibly not but with a 6.1 board it might bring it into parameters

Can you please post your current VCDS AUTOSCAN?
As found, don't clear any faults and don't edit the scan.
