Blind spot info system

[Classkawa]

This is one of the options I do choose to use in the car but mysteriously stopped working yesterday and I can't get it to turn back on.
In pic 1 you can see it is now Amber, instead of green. When I try to change this pushing the scroll wheel it goes blank, see pic 2.
If I try and access settings through the infotainment screen in the Driver Assist System Setup screen it says 'settings could not be retrieved' see pic 3.
Any ideas I can try for turning the blind spot system back on?

If you have followed the instructions for switching  it off and on, as shown in the drivers  handbook without success  (page 430 in the online version I have)   then maybe the orange light is telling you the system is not currently working  properly    The handbook lists  various reasons the system may not work properly  ,such as splashes, bad weather, interference from nearby electrical equipment  , dirty rear bumper etc.   If none of these apply you may need to contact the dealership.

I have found interference into these systems affected predominantly by dirty windscreen affecting the camera .

This system does NOT work with the camera, but with radar sensors in the rear bumper.

Thank you for the suggestions it really does help. I don't think it is dirt as the car is still pretty clean. It had its second service last week and the dealer did a valet on it.
Jazzik - do you know where the rear radar is located as I will clean it to eliminate it before going back to the dealer as a last resort

Quite a few things in that list

...Does it not use the camera at the front to detect when the vehicle has gone passed?

[Kremmen]

I didn't think so

My thoughts are it just picks up vehicles in a set zone to trigger the warning

[Jazzik]

Indeed. And if I would like to detect if/when the vehicle has gone passed I have my dashcam...

It has nothing to do with windscreen camera detection. The handbook says the radar detectors are inside the  rear bumper in the corners  .These are still able to detect vehicles along side you until they move far enough ahead to go out of their range. By which time the vehicle is in your line of sight.     I had initially assumed the detectors were in the door mirrors, but I think thats just the warning lights. 

 I think a similar thing happens with the parking sensors. Even when reversing it keeps the two outside front detectors working. Even though you are moving backwards they still operate over a wide enough arc to detect  an obstruction if your front wing swings out of line.

Just by way of a partial update on this. I spoke to my local dealer and they said to bring it in as the the blind spot system is a part of the the safety package, along with RDMS, where it should default to on every journey and give me the choice to turn it on or off. Clearly it isn’t doing that so I think it has developed a fault.
I will post back after the 11th once they have had a chance to look at it. Be interesting to see if this is a software or hardware issue or just me being dim!

Sods law will dictate that when you get to the dealer it'll be working

Just hope there are some fault codes

The blind spot system saved me once, I was about to join the straight ahead lane when a White Van man decided to overtake on the diagonal lines, the warning was enough to avoid an accident. See the aerial view of that junction in attachment.

.. It looks like they used to use the front camera as well  but don't anymore.
