Audi A8 euro blindspot mirrors: Installation, Fitment, thoughts, experience (you know the drill)

Well, I've seen these advertised on several group buys I thought, "what the heck, I'll give them a shot”. I apologize in advance for the dirty picture of my mirror.

The highlights:
- Very easy DIY installation. You can handle each side in 45 minutes (tops)
- Fairly inexpensive...unless you have auto-dimming mirrors (see below)
- I only installed the drivers' side mirror. After a month of use, I plan on buying the passenger side.

Bottom-line: Has made a noticeable difference when navigating in traffic (most of my driving is on the highway). These will probably make a bigger difference if you drive a lot in the city.

Description (I pulled this from another website): Why these mirrors aren't available outside of Europe, we may never know. The Blindspot Mirror Glass adds safety and security to your vehicle, allowing you to see objects both near, far, and in areas that are normally easy to miss. While basically normal by all appearances, these European Blindspot Mirrors are curved (aspherical) at the outermost edges, allowing for greater range of view.

Fitment for Models/Years: C5 A6/S6/RS6/allroad MY1998-2004
(FYI - the mirror glass from a B5 A4 (MY1999.5-2001) and B5 S4 (MY2000-2002) is the same glass/part used in the C5 A6.)
- C5 A6 MY1998-1999 (those with the smaller passenger/right side mirror. For this car, I am not sure if someone offers a blind spot mirror for the smaller exterior mirror. You might need to install an exterior mirror housing from a newer C5 A6. Sorry, other than that…I can‼sup>TMt help you there (hint: search the forum for any details from those that have done it in the past).
- C5 A6 / S6 / RS6 MY1999.5-2004 (V6 and V8 models all have the same exterior mirrors)
- C5 allroad MY2001-2005 (V6 and V8 models all have the same exterior mirrors. I believe that only offer the allroad versions)

Part numbers (via for C5 A6/S6/RS6 (1998-2004) FYI - I used the part#'s that they gave me for the B5 A4 1999-2001 as they share the common part; also a part# starting in 4B0-XXX-XXX might work).
Auto-dimming, heated version

NONE auto-dimming, heated version

C6 A6 from 2005 - ?:
C6 A6 MY2005+ ? I believe the B6 A4/S4 (and possibly the D3 A8) share the same size/shape exterior mirrors...but I'm not positive (I posted the question on the C6 A6 forum a month ago…and I didn't get a response). In this scenario, you could add the euro blind spot mirrors as they are listed on (both auto-dim and non auto-dim) under the parts section for the B6 A4/S4 (MY2002-2004).

Part numbers (via for C6 A6 (and possibly S6/RS6…when available):

What if I have exterior auto-dimming mirrors?:
Chances are, most of the C5 A6 owners have the convenience package with interior/exterior auto-dimming mirrors. I've noticed that the auto-dim blind spot mirrors are ridiculously expensive (Ouch! $500+ for a pair). Incidentally, the dealer charges $200/each for a replacement auto-dimming mirror (non euro blind spot).

Based on my research via the Bentley schematics, the three (two exterior and one interior) auto-dimming mirrors all work in concert together to adjust the dimming of all three. You might ask, "how do you know this?"...well my 2001 A6 didn't have the convenience package...and I REALLY wanted the interior auto-dimming mirror. Well, back in June 2002, Achtuning was running a Group Buy for the interior auto-dimming compass mirror for $200. What a bargain! (If you search on you will see the compass mirror listed for $250..but it is backordered). I then consulted the schematics in my Bentley manual and spent some time on the phone with the Audi parts department to figure out what parts I needed and how to hook it up. If anyone would like to add an interior auto-dimming mirror (and/or compass version) to their A6...just drop me an email ( I can send you the parts info for the wires/connectors etc. See also this great article by Joshua (Compass Mirror Tech Article)

Behind the exterior mirrors you will find a separate wiring harness (two wires - see link/pix)
that connect to the perimeter black membrane of the mirror. FYI - this black membrane is auto-dimming sensor.

I don't see why you wouldn't be able to just disconnect those wires and install none auto-dimming [euro blind spot mirrors]. Of course, all C5 A6's have heated mirrors, so these are all heated as well.

Thoughts after 1 month of use (based only on drivers' side):
This mirror has already saved my a$$ twice while driving on the Mass Pike (Boston area). If you drive with these mirrors....then drive another car (i.e. your spouse's car), it will be a bit disorienting. I've grown accustomed to that added visibility...but when I go to drive my wife's 2005 Pacifica....I need to take some time to adjust. Of course, you could always just buy euro blind spot mirrors for both cars. Problem: solved! On the flipside, if someone (i.e. your spouse) else drives your car, then he/she will need to adjust to this convex lens as well...because it takes a little while to adjust to them.
