I have a 1999 A6 2.8. Either the memory seats are not working, or I can not figure out how to use them. With the "STOP" button in either the up or down position, it will not work.

The owners manual says I do not see anything change when I press the button. Where is this OFF light at?

Also, my dome light does not turn on when I open any of the four doors regardless of the switch position. It will turn on manually when switched to the "|" position. The lights under the dash do turn on when a front door is opened. The lights under the front seats also turn on when a rear door is opened.

I was wondering if there is a connection between the memory seats and the dome light since both rely on knowing if the door is opened. However, since the lowere lights do turn on properly when a door is opened, it doesn't seem probable.

Also, when I used VAG-COM to scan for codes I did get two regarding the electrical, and am not sure if they relate to the problem:

Any advice would be greatly appreciated!

 

I have a '97 A6 Avant. I cannot say for sure if our memory seat works the same. I do not have an "OFF" light. When my red ON/OFF switch is up, the system is off. To set, you have the system on (of course), then press the memory button and the storage number simultaneously.

Hope this helps. Hopefully, someone with a '99 A6 will chime in.

Make sure you set your mirrors as well. Each memory position remembers both seating and mirror positioning (outside only).

 

I contacted Shokan and they'll sell me a seat memory switch for $65 used. Does anyone know if this is the unit that actually controls the memory seats, or is this simply the buttons and there is a control module some where else?

 

I found a post on another forum regarding this, and they say it's a common problem.http://forums.audiworld.com/a6/msgs/632334.phtml

This one guy says you can remove the switch w/o removing the door pannel, the other says you need to.

anyone know for sure? I don't want to break anything, but if I can avoid taking the door off, there's that much less to break!

Also, my mirrors auto adjust down in reverse only sometimes. could this be related? Also, I think I looked in the owners manual and didn't see this listed as a feature, does anyone elses's mirrors auto adjust in reverese?

 

I'd go for the plastic putty knife removal technique. Just go slow, be gentle, and don't fight it too much. LOTS of things come out this way.

If the corrosion looks minor, try cleaning it off with a pencil erasure or very mild emery cloth. You may be able to get out of having to replace the part.

The right sight rear view mirror will only tip down when you have the adjuster **** pointed to the right side. It does this to assist with parallel parking (so you don't ding your wheels on the curb).

 

I got the switches out using a flathead screwdriver. I saw no corrosion near the connector so proceeded to disasemble the unit (used a T6 Torx). The circuit board is very brown where the pins solder to the board. I have included a pic!

Thanks for the info about the mirrors...couldn't find that in th owners manual.

I have Access to AllData Pro online. It says that the memory seat is ODB enabled and can be scanned with a VAG 1551.

Here's the instructions, can this be done with VAG-COM?
