Traffic sign assist inoperable
I get a "traffic sign assist inoperative" message every time I start the car. It used to work at one point, but now I always get the message and it didn't fix itself ever (even after restarts).
All other systems that seem to rely on the same cameras work ok. But not traffic sign assist.
Can anyone help ?

Confirm it is activated.
The system may be either functionally impaired or temporarily unavailable if:
- visibility is poor, e.g. due to snow, rain, fog or spray
- there is glare, e.g. from the sun being low in the sky
- there is dirt, ice or misting on the windscreen in the area of the camera
- traffic signs are hard to detect (dirt, ice, snow)
- there is insufficient illumination of the traffic signs in the night
- signs are ambiguous (e.g. traffic signs on construction sites or in adjacent lanes)
- the information in the digital street map of the navigation system is incorrect or out of date

Forums of all car brands look the same as every car will have something that either won't work right or is disliked.
But more electronics means more can go wrong. Since you are under warranty, this should be easily fixed...

The S Class is a grey market import to India. (Because India has high prices for crappy specs). So it has got no warranty at all and was sold brand-new from the UK "as is". Traffic Sign Assist used to work (atleast for some signs, remarably), but all of a sudden it mentions its inoperative. Every time I start the car, I get the warning message that its inoperative.

Although purchased grey market without warranty, check with MB UK & India in as much as they are not legally responsible feature worked and now malfunctions they “may” offer goodwill assistance to resolve the matter or at least definitively diagnose it.

I am surprised that it even worked at times.
Traffic signs are typically speed limit/end-of-speed limit signs, no passing signs etc.
Since the assistant uses both navigation and traffic sign recognition, it may have been disabled due to missing nav data (do you have the Indian Nav data loaded?) and the signs must look the same as in the database. I remember seeing some signs like in Europe and then several that appear Indian.

realized it was in a different country (India)
Going to the India dealer isn't that easy. The UK dealer told me not to take it there for arleast a year, because the India dealer will report the car as taking away from India sales and reports it to Merc. That gets the UK dealer in trouble. And the UK Dealer hooked me up with a sweet full option customized S Class.

Most likely it never worked in India. SLA needs backup data from the navigation database and if that is missing, it does not work even if the camera properly detects traffic signs.
VladimirCDI sells a CAN filter that "enables" SLA for countries that do not have speed limit info included in the navi database. Not sure how it behaves on an S-class, I know W204 shows the speed limit only momentarily which is hardly of any use.

Audi and BMW may have had these longer but the W222 does have the speed limit info also on HUD (instrument cluster momentarily and Comand permanently as well as on the HUD). This is for the Euro market though.

I would like to turn this feature on - regardless of whether the vehicle is a USA or Canadian or whatever.
Same for a lot of little functions like "spotlighting" etc etc.
Does anyone have an electronic tool to do such things - anything out there?
For example Porsche has "Durametric" - anything like that for the S Class?
