Hi guys, so did this feature came as standard or optional on all e34s? or did this started at some specific year? id love to have that feature, but im not sure if i do have it and its not working, or if its just not there. and in that case, if its possible to retrofit it.

I dont see any specific info regarding the mirrors (which have automatic heaters as i found out).

It was part of the electric memory seat option.

Yes, part of the SMM = seat and mirror module. The mirrors are different inside, more wires also, the plug is different and the mirror switch is also different. Without all the gimmicks on the driver seat that is not possible, because the memory module has to know the driver seat height, position of the backrest, position of the seat, position of the mirror, here a detailed training manual of the SMM, this module was used in E32, E34 and E31, once during the production years the module was changed, not interchangable

I have that also in my E32 750, different pulley and belts that the visco fan runs faster = cools better

I dont see any specific info regarding the mirrors (which have automatic heaters as i found out). >>>not mentioned as optional extra as it was standard

oh, i see so retrofiting this wont be an easy option ... i guess ill have to stick with the manual version :P

As for the hot climate option ... yeah since we have sub tropical weather here, it seems to be quite common to have those.

Its weird that the person who optioned out this car, chose that, and 314 Heated Windscreen Washer Nozzles Frontscheibenwaschduesen Beheizt
I mean ... we dont have really harsh winters here. And even if we did, there are better options rather than heated washers ...
