P2 here, rear door lights DO illuminate. My puddle lights in the side-view mirrors, however, do not.

p2 = rear coutesy door lights
p1 = NO rear courtesy door lights = cheapskate MBUSA

you need to get your dealer to flash the software to turn on your puddle lights. There is a separate thread on puddle lights which tells you how. Apparently all Bluetecs are OK, but most gas versions need to have their puddle lights activated.

Hope this helps,
Steve

Totally right. BLT with P1, no rear door lights, puddle lights work.

Appreciate the clue on removing the lens. W166 '13 GL Bluetec does not have rear bulbs either. I tried having them replaced with LEDs and the tech told me there is nothing to replace inside.

An irritating but common thing that goes on, especially w/ manufacturers that do a refresh mid-way through a model's lifespan. There always seems to be a feature or 2 that the outgoing model has but the new one does not. And then when the refreshed/facelift comes out, that feature appears again. 1st example that comes to mind is that the 2011 e90 BMW 3 series had LED rear turn signals. The new 2012 F30 3's went back to an incandescent bulb. Now the 2016 facelifted/LCI models will again have LEDs. Just gives you something to "upgrade" to I guess.

On the S class there are standard, but my rear passenger door one won't light for some reason,. Already swapped a light from the other side that works, and still doesn't on that side. Strange... Ideas?

No Wires!Fake!

I had a 2016 c450 and they had lights that worked on the rear and replace them like flex Alexander from you tube and they worked well!
Got rear ended and car was totaled! Bought a 23 c300 and no wire in rear.Just got my 24 c43 and guess what ? As much as I paid still no wires in rear door! Just plain disappointed!
