I have it on my datacard and also saw it in this post.

Any info on this? What is it's purpose?

Maybe there is no rotating light?

I found another reference in this post (at the bottom)

952 is Sport Package Suspension

For a W211, 952 is decoded as above. When using the Russian site, you would have to take into account that it just gives a set of different interpretations for an option code if it has multiple ones. You should then figure out which interpretation applies to your car (usually straightforward). Sometimes the correct code interpretation is missing (or the interpretation is completely missing), this makes reading a bit more challenging.

Gotcha.

Maybe they're funnin' that more rotating red lights will be around you with the sport suspension (police)
