Audi A4 B9 8W automatically dimming exterior mirror retrofit package

Significantly enhance the look of your AUDI A4 B9 8W with the original automatically dimming exterior mirrors / mirror glasses.

Simply retrofit this convenient system into your AUDI A4 B9 8W yourself.

This is much more pleasant, especially at night, as the two outer mirrors will no longer blind you.

You can decide for yourself whether you want to upgrade only one side (e.g. driver only) or both sides (driver + passenger), both mirrors are "independent", it is not necessary to convert both sides.

After briefly plugging it into the very easily accessible OBD diagnostic interface in the driver's footwell, the KECODI coding interface supplied here uses the innovative KECODI that is already preset for you to fully automatically activate the automatically dimming exterior mirrors.

Scope of delivery:

• - 1x original AUDI A4 B9 8W mirror glass dimmable (according to selection)
• - 1x pre-assembled cable sets (according to selection)
• - 1x KECODI interface
• - 1x KECODI interface storage case
• - 1x installation instructions (German)

Please select which side you would like to upgrade.

Product attributes:

The retrofitting of the original automatically dimming exterior mirrors / mirror glasses is possible on all AUDI A4 / S4 / RS4 B9 8W models of all years of manufacture (pre-facelift / facelift), all body styles (Avant, Sedan, allroad) and all equipment variants WITH an already installed automatically dimming interior mirror.

Models without an automatically dimming interior mirror currently installed must be upgraded in advance; we can also offer you this retrofit package under item number: 13340.

This retrofit package will be prepared for you depending on the chassis number you provide.

If, for example, the exterior mirror heating is installed, you will of course also receive auto-dimming mirror glass WITH mirror heating.

The supplied cable set connects the mirror glass to the door control unit inside each door; it is laid along the existing cables.

Product compatibility:

The vehicle manufacturer installs 3 different door control units (Lowline "3", Midline "5", Highline "7"), each of which enables more or fewer additional functions. The function of the automatically dimming mirror glass requires at least one Highline door control unit "7".

Generally speaking, electrically folding exterior mirrors are already installed - so this retrofitting works without replacing the door control units.

To determine this, you can read the door control units with a tester to determine the part number - you can compare this with the following overview:

Structure of the nine-digit part number: XX0-959-?9X + (index letter such as A, E, H, etc.)

Here the position of the ? (question mark) is crucial.

? = 3 = therefore unfortunately not suitable - the door control unit must be replaced.

? = 5 = therefore unfortunately not suitable - the door control unit must be replaced.

? = 7 = all functions possible - suitable for this retrofit.

If it is necessary to replace the door control units, these can also be obtained from us at any time under item number: 16500.
