Rear heated seats fitted!

So i managed to get hold of a very rare set of rear heated seats!

I was asked to source a set of leather seats for an A3 by a friend who has a bad back, i suggested he gets seats with Lumbar support but finding that for an A3 is somewhat difficult. I suggested that he get a set of A5 seats as they all come with lumbar support but fitting them is more of a fuss than he wanted. Eventually i found a very rare set of fully electric full leather heated front and rear seats with lumbar support and with the through load system and rear armrest!

I was ready to buy the set just for the rear heated seats but as it also has the front lumbar support my friend bought the set and let me have the rear heated pads.

So when i got my hands on the seats i first noticed that the main cable that comes from the pads to the car was cut off so i had to figure out what wires were what and remake the loom.

Also as i have half leather seats i needed to swap the seat covers so i got to work stripping the seats down.

I moved the pads over and built the seats back up, once done you would never be able to tell that it was stripped :)

With the seats all sorted out i fitted them back into the car... now the next thing was to get them wired up!

So i ordered the rear seat harness from Kufatec which connects the seats to the switches and fuse box. I also sourced the parts for the rear switches and once i had everything i got to work one Saturday and stripped down the car.

I took out the centre console at the same time as i was also doing the US centre console conversion which you can read about here: http://www.audi-sport.net/vb/a3-s3-...092-u-s-sytle-cup-holders-centre-console.html


While i had my A5 S-line front seats out i also fitted in the under seat storage i bought for them

Once i had the console fitted in i continued to finish off the wiring for the rear heated seat so i took off the side plastics and lifted up the carpets to run the wires

The switches also lights up at night which looks really cool... i only had one switch in when i took this shot when i was testing the switches to make sure i had the right and left ones correct

They work really well! The seat occupancy sensor within the pads also stop the seat from warming up if left on accidentally without anyone sitting on them. really pleased with this retrofit!

That is a brilliant OEM upgrade. Great work doing it all yourself. Didn't even know you could get heated rear seats.

Thanks guys!
One of the first A3's I saw when I was looking to buy about 5 years back had the same half leather with front and rear heated seats... Missed out on that car and have always wanted it since. I think Audi stopped offering this on the A3 around 2007, probably wasn't selling well. Really nice for any passengers in the back on a cold winters eve

Don't know if it makes a difference but my 2012 S3 has heated rear seats fitted, so might have still been an option.

Hey mate,

@Ash187

Sorry to dig this old diamond up but how did you wire the back seats?
I'm looking into doing this retrofit since I did frontseats aswell.

I can get all the parts but I'm not sure how to wire the backseat to the control panel (power, buttons etc..)

Hope you can help me out bud!
Nice work.

Holy thread revival! its been like 6 years!!!
I wired it up according to ELSAWin... I honestly cannot remember how without referring back to ELSA since its been years and I now wire up different around 5 mods on a daily basis.
as far as i can remember the rear seats connect to the control buttons in the rear centre console and then goes to the fuse box for power.

Well, I think it's a duable job then. Only need to get some wires and connectors then.

I was thinking of ripping out the heatingelements of some frontseats and lay those in the backseat :D.
But not sure if the connectors are the same, I guess not. I have ElsaWin but it's giving me a headace lately (need to set date and time to 2003 and even then the app freezes alot in my Win XP virtual machine).

Could you maybe send me a copy of the wiring diagrams in Elsa?
I'm happy you don't have to hook them up to the clima unit, it was a pain in the *** to pin those for the frontseats haha

Retrofit is a great job :)

Hi mate, I have a S3 with heated rear seats. They’re the silver/grey two tone seats and I don’t like them. I’ve bought some lack leathers and was thinking of swapping the covers over so I can keep the heated element. Problem being is I didn’t realise the back rest is heated also, will the bench still heat up if the backrest ain’t plugged in because I can’t see how I’m gonna swap the back rest cover over
