hallo!

this is great forum,so I wanted to try my own instructions too. sorry for my english

Installing factory digital compass mirror in Audi A4 B8 and A5

i have now installed this in two early model year 2009 cars using two methods below.
both cars had side assist, dimming mirrors and three zone climate control from factory.

these instructions are probably not valid for cars with lane departure warning! also starting
from 11/2008 some changes are listed for mirrors not sure if those cars are different. my install cars
were older than that. check schematics and your dealer if necessary

digital compass mirror is different depend in if your car has one or three zone climate control because
mirror includes a climate sensor behind it in three zone cars and not in one zone cars.

cars with one zone climate control use compass mirror part 4F0 857 511 F with six pin connector. this part
has no holes in the base part plastic behind the mirror. you can also mod this to a car with three zone climate,
instruction below. this part is also for a6 and others i think

cars with three zone climate control use compass mirror part 8T0 857 511 B with eight pin connector.
the base part plastic behind mirror has holes in it that show climate sensor through them. the mirror should
come with the climate sensor (part 8K0 907 65 in there but if not see late in this message for instructions
how to move it from old mirror to the new mirror.

note that part number adds letters to end depend on car interior colour. 8T0 857 511 B Z62 for example is
mirror for default light interior. order correct part carefully


method 1:

when installing correct part for one or three zone climate control cars, installing the mirror is
easy. this is same for one and three zone climate control cars, just the mirror part is different.
order correct part for your car, see above.

this method is same for a6-q7 cars too i think.

when you get correct mirror:

disable battery power for safety.

first remove the vertical cable cover above mirror by pulling it out downwards. wiggle it maybe.

remove connector.

turn old mirror counter clockwise until it frees

put in new mirror, turn clockwise until snap.

connect new connector to car.snap in place.

replace cable cover.

reconnect car battery.

switch on ignition. mirror shows C. if not see car manual how to activate compass.
basically control it by holding down mirror button enough times.

read car manual for how to set compass zone and calibrate by driving a circle. done!


method 2:

when installing one zone climate control mirror part 4F0 857 511 F to car with three zone climate
control. (for example if you source a used part)

see method 1 how to remove mirror from car.
then go to a table to continue work on mirrors.

your old mirror has 8 pin connector and new mirror incorrect 6 pin connector.

remove 6 pin connector plastic from new mirror cables. you will not need it.
connector has small plastic lock you must lift open before removing it.

write down pin numbers and wire colours from old mirror 8 pin connector.
remove 8 pin connector plastic from old mirror. store safely.

remove base part plastic and climate sensor from your old mirror. you need this later.
to do it, pull left and right the base part plastic from top and push down. it will release.
remove climate sensor connector and base part plastic with sensor is now free. store safely.

remove base part plastic from new mirror. you will not need it.

looking at cables you see new mirror has all same cables as old one with same
colours but not pin 7 magenta-yellow which is climate sensor.

old mirror also has bigger metal heads in cables. new mirror has too small.
take metal heads from old mirror cabling and put them in the new mirror cables.
so pins 1 to 6 are easy. little mechanical work. needs experience

but you need to wire the climate sensor too: power, ground and sensor wire.
old mirror has a cable for this.

cut out climate sensor cabling and its small 3 pin connector from old mirror. remove
black tape to reveal old mirror cables so you can cut them out full.

steal power to climate sensor from wire 1 (white) and ground from wire 2 (black)
in new mirror cabling. if you open old mirror cabling you see that cable does the same.

wire middle pin 2 magenta-yellow in 3 pin connector to pin 7 in the 8 pin mirror connector.
you can cut pin 7 cable from old mirror cabling and use that.

finally fit 8 pin connector plastic to new mirror cabling you made, same
colour cables to same pins as in old mirror cabling you wrote down earlier.

so then your new mirror should have these cables using the old 8 pin connector:

- pin 1 white
- pin 2 black
- pin 3 grey
- pin 4 yellow
- pin 5 brown
- pin 6 green
- pin 7 magenta-yellow
- pin 8 (empty)

and small connector for climate sensor wired up too:

- black (in pin 1, connected to black pin 2 in 8 pin connector)
- magenta-yellow (in pin 2, connected to magenta-yellow pin 7 in 8 pin connector)
- red (in pin 3, connected to white pin 1 in 8 pin connector)

connect climate sensor to 3 pin connector and push base plastic back in place.

do confirm all connections from your car schematics!!

mod for mirror is now done.

see method 1 how to put all back in car.done!

hope this help!!!

i emailed this to mlk for his a6retrofit site too.

Thanks SplendidAudi! The slightly edited version is now here:

If I understand it, it is for cars, which already have dimming mirror.

What about, how to install dimming mirror to cars with no dimming mirror?

SplendidAudi

igi does your car have three zone climate? if it does you may already have 8 pin connector with power wired to it under wire cover above mirror. or you can steal power and ground from rain sensor power if you have that

digital compass mirrors are always also auto dimming mirrors

i think you need to connect at least mirror cable pins 1 white power, pin 2 black ground to compass/auto dimming mirror to it to work.

three other pins are for auto dimming side mirrors. not needed

one pin, can not remember which, goes to convenience module to turn off dimming mirror when reversed but that may not be mandatory. try with just power

try to see if you have a 8 pin connector under wire cover?

please report to us if you check it

Igi

I have three zone climate.
Not sure it is 8 pin, probably yes, when I have looked, it has had more pins than my wife's A4-B7 which has have dimming mirror 4F0 857 511E.

Igi:

Then it might just be a matter of swapping your mirror to the three zone climate version of compass mirror (part number in Splendid's article) if the connector is there already under the wire cover?

brs

Could any one help me with the opposite problem; I have a car with a 6 pin mirror connector and have bought a mirror with 8 pin connector.

I have this from XXX:
6 pin connector:

Pin 1: black/red - Constant 12V
Pin 2: brown - Masse
Pin 3: red/yellow - Reverse signal
Pin 4: purple/white - Sideview mirror dimming Driver side
Pin 5: purple - Sideview mirror dimming
Pin 6: white/yellow reading light connector

Could anyone make the same commente on the 8 pin connector, giving mew the correct assembly of the 6/8 pin converter.

Thanks a million !

Igi

I have changed my mirror to autodimming mirror, thanks to Kufatec (mirror and cable for 149 EUR + shipment, but don't try to find it on their webside).

In truth, I had to use only 2 cables from cable harness - 1 for + from pin6 to pin 6 of 8pins connector in upper light and 1 from mirror to comfort module for reverse signal (i didn't connect it yet, I am not sure it is necessary).

So the most difficult thing was to disassemble the cable harness.

TexasEric

Anyone know where Audi hides the connector on a B8 A4 when the cheap-o non-dimming mirror is factory installed? I want to add the dimming mirror, but at quick glance, I did not see the connector inside the sunroof controls.

Igi

It's in the mirror.
