Safety Features Inoperative

[Billyboro]

I have a W212, E250 AMG with Blind Spot Assist, Lane Departure Warning and Distronic Plus.
I have noticed that on the M6 between Knutsford services and Sandbach services both North and Southbound i receive a warning message on the instrument display that says 'Distronic Plus Inoperative
Blind Spot Assist Inoperative, Pre-Safe functions limited'.
This has happened on every occasion on this stretch of motorway.
Has anyone else had the same issues?

Distronic functions will be disabled when close by radio/radar installations. Should be noted in the handbook.
Anything of that nature in the vicinity?

Jodrell Bank radio telescope?

Distronic airfield radar interference

Evidently uses GPS co-ordinates to switch these systems off. Jodrell Bank is a passive device it receives signals rather than broadcasts them. Air traffic radar is the opposite of course but I believe the MB systems also are deactivated if they detect strong interference signals
