Retrofit A4 B9 S-Line seats into B8.5

[Hkcheesemonkey]

I’m looking to retrofit B9 S-line leather seats into my facelift B8.5 Avant which currently has standard cloth, heated seats. Noticed there was another thread for the massage seats, but I’m just looking at the standard S-line leather seats, heated, maybe manual, maybe electric. Can anyone advise on 1. Whether this is possible, physically - is it plug and play? 2. Any mods to electrical connections required? 3. Is there a guide or video anywhere?

Highly unlikely that they will be plug and play as it’s a different wiring set up on the B9 compared to the B8.5.

It will certainly be possible, it’s a case of digging though the wiring diagrams and comparing the differences and then creating an adapter harness.

If your current seats are not electric then you will also need to add the additional wiring which powers the motors and will be on dedicated fuse - certainly can be done. We have added power to S3’s which have had supersports seats added.
