Auto-dimming electrochromic mirror dirver-side only?
Maybe i'll test the mirror with a AA battery (1.5V should be safe).

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

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.

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.
In Europe both outside mirrors are convex showing wide (smaller) picture to the driver, but I believe the auto-dimming feature is present in both of them. I'm not sure but I think both mirrors have it.
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.
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
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
- 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 !!!
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
european countries do not allow undertaking
watching youtube clips of how u guys use highways it should be banned there urgently
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
