Can that perhaps be enabled?
you are looking at a picture from W222

I'm going to open it up again and see if i messed up somehow (i don't see how, you can't switch plugs as they're all different).
Maybe i'll test the mirror with a AA battery (1.5V should be safe).

Well i found the problem: my door module does not have the 2 pins for the electrochromic mirrors


Passenger door module. The bottom 2 pins of the black connector are wires for electrochromic mirror but there are no corresponding pins in the door module.

Partnumber of the doormodule without electrochromic mirror pins

Well i did find a passenger door module on eBay with partnumber A2219001101 that does have all the pins of that connector populated.
I'm going to order it and see if anything works with that module.
Running a wire from left door to right door isn't really a viable option afaic.

UPDATE: it works!

I bought another module from eBay with number A2219001101.
Installed it (pretty easy) and everything works out of the box, without coding (YMMV).
Wonderful. Thank you @BOTUS for insisting that it works.

Issues with auto-dimming mirrors can be surprisingly annoying, especially when only one side decides to act up. It’s one of those small things you don’t think about until it stops working, and then suddenly every glare at night becomes a problem. I’ve been through similar headaches while dealing with minor exterior fixes on my own car, and while searching for solutions I ended up reading a bunch of user experiences

My UK '06 S500 only has auto dimming on the drivers side and interior mirror.

It now has a dimmable mirror glass on the passenger door to replace a failed heater on the original one but no wiring present for the auto dimming feature.

Presumably this is just a harness to the door ECU and a box tick on Xentry.

you need to run two new wires - the door trim can stay on - pull the half moon plastic madness and use a long screwdriver or such to ping the clips to release both the white and black multiplugs for the mirror - the door module coding is already set to work it

did mine about 5 years back - works faultlessly - without it, it means you can't see where you are going on the motorway - BMW always managed BOTH mirrors, so for Merc its either incompetence or criminals, rather than some mandatory drivel making it illegal

can't help with pinouts as not with the vehicle for a few months

parts plebs won't help you get a loom as you need a german vin

Hard to find a good picture... i guess this one shows it:


Angle of the mirrors to the car is different

further to this query - those are Facelift mirrors

all my posts relate to the OEM rounded prettier mirrors used in Europe between 2005 and Aug 2009 - and the angle is identical AFAIK - why would it change....

2010 model year went with the squared off strange ones - which I do agree withe right bodykit / bumpers and later lights, does update the car to a more modern looking thing

No no no... NO!
You can see it here, look at the length (and angle) of the mirror base:

well yes - somehow yours are different... will have to study mine when back but when I wash it there is not substantial different length of the stem on my UK car

- I actually never did the mirror swap - I bought a German one and un-threaded the two wires coz I'm pedantic and wanted OEM wiring - but would be easier to pull though wires and crimp on new pins

- never saw a difference in mirror housing and sat beside both for hrs doing the wires - it must be some USA madness - from 45 years back when I worked on cars all the USA vehicles we saw did mirrors wrong with loads of unnecessary complexity that gave a pathetic image that was no use to a normal driver - I remember one new Jag had all this **** written on the glass to highlight the cars weren't a real size Doh !!!

it appears you are talking at crossed purposes to where I'm coming from - you are USA market ? all along I said USA do mirrors strange and always have, due to some weird beard legislation certain states mandate

most European spec cars do them the same like they should be - both mine are identical - I can sit in the left and set both mirrors to work just as they do if I sit in the right

its not unheard of for Merc to mess the world up for all markets - go back to the w124 e class and yes those halfwits invented insane odd shaped height and length - and it was awful swap the joke passenger one for a real one and see twice as much

and on my fathers early w211 the mirrors (same housing but worse due to USA large image madness) are mounted against the car and you can't see anything... later they added the needed gap with some freaky looking things in a facelift

maybe as you allow undertaking - USA try to get a better image directly behind the car on the passenger side....

european countries do not allow undertaking

watching youtube clips of how u guys use highways it should be banned there urgently

multi lane highways are a joke - it flows far less traffic

in last 10 years - idiots here stole the hard shoulder (emergency lane) on busy sections of motorways (your highways) and now you get many badly used lanes, terrible lane discipline and more congestion on 4 lane roads than we did with people concentrating when it was 3 lanes - deaths and accidents have gone up and they close the roads for any incident they can think off.... all part of the plan
