Memory seats retrofit

Hello,

One thing I am really missing in my car 2015 etron is the memory part of the electric adjustable seats. My wife is about 10 inch shorter than me , so you can imagine my routine before I can even get in the car.
That made me think: why isn’t this in such a premium brand, there are plenty examples of it in less “high class” brands and secondly wouldn’t it be possible to somehow retrofit this by using donorparts from another mqb car ? Maybe Passat or Skoda? They have the buttons in the seat? Once memorized with the keys you could even live without the buttons.

Here’s a link of a guy who was quite far using european parts in his American golf, but didn’t present the result:

It's an expensive retrofit as the memory controller is part of the base of the seat (at least in the A5 range this is the case). Most A5 coupes have this part which makes it easier to retrofit but don't believe that's the case for the A3 range.

I think there are better chances for the retrofit to work if it uses parts from another car in the MQB platform, as Can bus control messages in other platforms may be very different. Also, along with memory seats, a complete memory system usually requires memory mirrors, which can be a problem because in the A3/S3 8V only the passenger side mirror has such feature. Including memory in the driver side mirror would require replacing the mirror glass motor and connector and adding 4 wires to the mirror loom. Door control modules seem to support memory mirrors, but there may be parameterisation issues.

Hmm, didn't think about the mirrors . However I never heard anybody about paying attention at memory functions when swapping their mirrors for retractable ones. And there are cases of memory function with and without electrical steering column , so might just also function without the mirrors.

Yesterday just experimented a bit with the 5F module and turned the seat menu on. It displayed but obviously greyed out. ("stoelen" means "seats")

I’m almost there !! Got it working with parts from a Superb Skoda. Temporarily with the buttons on the seat, working memory with the preset numbers and the key also works. When opening the door the seats moves to the desired positions.
Later gonna try the q5 switch via the doormodule.
For now I’m desperately seeking canbus comfort location. For testing its connected in the door

Impressed :)

Memory seats are an option on the new 8Y platform. Parts and coding "might" be compatible with the 8V.

Beautiful!!!
Very nice 'retrofit'.
Does it work as expected? Do mirrors, etc also move to the correct positions? Coupled to specific keys?
Do you have keyless entry?

Works as expected, preset numbers work , storing memory results in a short typical beep, same with connecting it to a key. I have kessy also no problem, once you open the door , either keyless or remote fob it immediately goes to the preset position, including right mirror. This is because of the mirror-dip in reverse (Lhd) it’s already equipped with a memory motor, left side is optional , should be possible by replacing the motor.

Next phase is trying to get q5 memory buttons in the doormodule to make it more Audi -ish

Not working: easy entry, tried a lot of coding but still no actions And still my “seats” menu on the MiB stays grayed out. (Unavailable ) not really important but still.

@DJAlix Nice to hear even the master of retrofit is a little impressed for the past days I learned that there is a lot exchangeable between the seats of the Vag-concern .

Anybody can point me in the right direction for comfort canbus ??

Good job! That's something I'd love to fit in my A3 but I'm afraid it would have too many limitations since I don't have kessy.

Convenience canbus is connected to pins 5 and 15 on the Gateway module (J533), wires are orang/brown (LOW) and orange/green (HIGH). Is that the info you're looking for?

Mirror memory motors can be bought separately instead of replacing the whole mirror but you would also have to add 4 wires to the mirror harness, which can be a lot of work. The wires are sealed in a plastic tube that may not fit additional 4 wires, especially if your mirrors are power folding, auto-dimming and have side assist indicators.

Yes that’s the one J533 colors are exactly right, but where’s that &@$% thing? Location pic?

Besides no kessy is no problem, just buy a cheap used ugly memory seat , which in fact is 95% of the total costs !

Passat / superb / octavia even tiguan I would guess , buy one put it together with your seat upside-down on a table and start comparing for half hour. If you don’t trust it bring it back (that was my backup plan in case didn’t work out)
If it looks good, start early in the morning

Mirror on the left is not that important to me , the difference in the setting between me and my wife is not that much. And luckily the right one works fine. Already read some stories about how difficult it would be working the extra wires through the mirror in the door. Also the costs of the motor are bit much considering the minor improvement imho

Gateway can be reached from the left side footwell. Really hard to reach in my opinion. Removing the lower dash trim and knee airbag will help. If you find it too difficult, you can connect to the canbus wires that go to the left door harness, at the A pillar bottom, or at the air conditioning control panel for example.

Tried it in under the a-pillar , behind the opening handle for the bonnet. Although there were really a lot of wires , and a lot of canbus ones , no comfort can. Even finding where the door enters the car, useless.
Might go for the climate one , but never got that one out of the dash.

Still learning...
