Comfort seats retrofit into A7/A6

[mobilejo]

If I got hold of a set of comfort (multi contour) seats from a C7, could I retrofit them into my A7?

I know they will fit physically to the floor mounting holes, but as the comfort seats are operated via MMI for some functions, I'm wondering if coding is a simple case of selecting the right options in VCDS (which I have) or if something more complex is required.

Has anyone done this already? Is it even possible to get all the functions working?

Thx, I'm on the verge of selling this car due to lack of seat comfort and this might be the only thing to prevent that!

I don't see why this wouldn't be possible.

[mobilejo]

I'm pretty sure it is, but I can't be completely sure.

I may play around with VCDS and see if there is coding in there for comfort seats that can be activated.

Reviving this old thread - Has this been done? I found a donor car with the comfort seat from a prestige S7 that I'd like to swap in my A7. the lack of lumbar in the passenger seat is a real challenge for my g/f on long trips.

Thanks!

If you bought a car of the quality that A6/7's are thought to be then why would they make a "comfort" seat? This implies to me that the other ones are not comfortable.

Same applies to steering wheels - there are so many kinds and it would probably be cheaper to agree on the best one for a sports sedan and then put it in all of their cars.

Very true, it shouldn't be required. But after 8 years and 10 BMW's (some with comfort seats, some with sports seats) I have learned that Audi S Line seats just aren't that great. At least for me (6'6). I was always okay in all BMW seats, even the basic sports variants.

comfort seats have massage and ventilation (and more adjustment?), hence the "comfort"

i don't think this implies the other seats are uncomfortable per se. although, living where I do, lack of ventilation can be pretty uncomfortable.

on a side note, I love this thread. it reminds me of how B5 and B8 forums (or name your platform that's been out a few years) eventually progress from "how much will my lease be?" to "i found a set of upgraded seats I want to retrofit into my car". the latter being far more interesting :)

It is frustrating. The non-Prestige models have very disappointing seats. Prestige seats are better, but still not what you would expect. In my opinion, they should have put the comfort seats without massage and ventilation in all the A6/A7 models, and made the massage and ventilation an option. Even if they had to raise the price of the car a little bit, that would be better than the current situation.

Yup. The standard seats in an A6 are not very good. My wife's BMW X3 is more comfortable.

FYI, the configuration you mentioned, the comfort seats without the ventilation and massage, is available elsewhere in the world.

It seems a fairly common opinion that the 6 has seats that are varying degrees of lousy. I have the heated and ventilated seats in the prestige and the seats are very poor, not only are they uncomfortable but the ventilation aspect is almost useless. They have 3 levels of vent: 1 = does nothing, 2 = just about feel it and 3 = it makes a lot of noise but still doesn't work like other manufacturers seats do.
It is, however, very curious that my A6 is the first car that I have owned that allows the heated seat to be enabled the same time as the ventilated seat. This allows the heated aspect to work very well as most seats just have a heating element but these seats blow as well.

It is not a good policy to charge extra for something that is inferior to what is alternatively available. You can get the basic lousy seats or pay extra for some heated and ventilated lousy seats or pay even more to get the seats that should have been provided in the first place.

It is similar to the entertainment system: you buy an A6 and you get a radio that is compatible to a Ford Fiesta. You can upgrade to a Bose and pay extra for a lousy radio or, for the price of an average Korean car, you can get a B&O. There are numerous threads regarding the after-market upgrade of the B&O so for $6500 you can still get a lousy radio.

They market steering wheels the same way: 1 - a lousy smooth leather wheel, 2 = a sport steering wheel with grippy leather and paddle shifters, 3 = a heated steering wheel that eliminates a useful button that allows different functionality and 4 = a flat bottomed wheel that should have been supplied in the first place. All of which have a space for a badge in the center spoke but they save .5 cents by leaving it blank. Unfortunately, they have dropped the 4 spoke wheel which I like because I frequently drive with hands at 8 and 4 and it allowed for a grip around the spokes. I would prefer the grippy leather, 4 spokes, flat bottomed, heated, with a selectable switch all with a badge in the blank spot.

While I'm on the subject of curious decisions, why market 2, 3 and 4 zone HVAC? None of these systems work very well but I digress!

I currently have the Sport Comfort seats, and the lumbar was much too obtrusive on my lower back even when all the way retracted. So today I figured out how to pull off the seat backrest cover (without breaking it - it's tricky). This exposed the seat guts from behind. I fitted vertical strips of foam on both sides of the seat-back between the lumbar support mechanism and the seat cushion, positioned so as to not interfere with the lumbar mechanism. This made the center portion retract relative to the sides, which fixed the lumbar problem. However, there was still too much extension of the whole lumbar region, with a "gap" in cushion at the base of the seat-back. To fix this, I stuffed a larger piece of foam at the base, and loosened up the lower ties to allow the leather to accommodate the extra foam padding. This worked wonders, and the seat is now comfortable, and the heating/fan/lumbar/etc functions all still work fine. I don't know if it just an "American" body shape/size problem (I'm 6', 200 lbs), but I had the same issue with my A6. I took a different route with the A6, and pulled out the lumbar mechanism tension springs, as well as added additional foam (custom fit) on the top-side of the seat and backrest, and covered them with custom seat-covers. This was very comfortable, but it eliminated the fan effects (not a huge deal) and made the heating more of an "eventually" option rather than instant feedback. On the minus side, it didnt' look the greatest with seat-covers, even though they did match the interior color. But I put comfort over looks as my cars are every-day drivers. Just my 2c worth for the more mechanically adventurous.

Adding the comfort seats (including ventilation and massage) is possible. I did this for my "summer seats". I have the S sports seats normally on my car, but on the summer because it is really hot i swap them with the comfort ones for the ventilation feature.

If you already have electric seats and memory than things are easier.

You need to get one more wire for each seat from the central electrics (12v) and then do the coding. Once you've done the coding all the functions will work as intended.

The only thing i didn't find how to activate are the MMI menus that show the massage features and seat cushions setup. These features work but without appearing on the MMI. I didn't dig too much about this since i only use these temporarily on the summer time.

There is also one component protection that you need to remove for the seat memory (which is connected to the steering wheel memory - if you have electrical steering wheel column).

Hope this helps.

Thanks for the info. Getting the MMI options don't concern me so long as I could actually still adjust the seat cushion features (bolster inflation etc).

I don't have electrically adjustable steering wheel, I do have memory and electric heated currently, so from what you are saying I would just need one extra wire from central electrics (live 12v) and I'm good to go?

Where do you access this wire and what did you connect it to?

Thanks!

Next time I have the VAG-COM out, I'll try to remember to check the coding options for the seats and post them. Don't know if that will help, as it may be the MMI (hidden options?) that needs to be modified to allow the functions to show.

[audi1]

I'm thinking about doing this comfort seat retrofit.
Can you post up does Vag-Codes for it ?

I bought a set of comfort seat for my A7 can anyone help me out with the wiring and coding to do the retrofit?

This is most commonly done by finding a car (new or used) with the desired options present from factory and cloning its module settings. Friendly people at the dealership can help with this.

[audi1]

I think there is very few A6/A7 with the multi-contour seats around but so far i found and option in 19 can gate way where you can add the multi- contour seats option.
I just need to figure out where a purple and a red/blue wire goes.

[netsecguy]

Audi1 - I too have looked into this. Had a shop tell me they could potentially hook up power and use the seat controls to control massage and adjustment, but not through the mmi. seems like we should be able to run through the mmi with the correct wiring harness. i've pulled my original seats and there are definitely fewer wires and relays. would like to find a salvaged s6/s7 or newer a6/a7 with comfort seats and pull all the wiring out for my car, along with the seats. i'm sure some vag programming may be required at that point though. best of luck!

Very interesting thread I am having a horrible time with my week old A7. The seats are killing my back about 30 minutes in to the drive.

I am hoping that the comfort seats could fix this. Dealer wanted me to trade in for an S8. Just a little bit more money ;)

The seats were the main reason I sold my A7 a few years back. Comfort seats or even the basic seats in the S6/S7 are a lot better.

[gta7]

Just hoping I get used to it. Nothing like researching the heck out of it and in the end looks like I made a very big mistake with these seats.

[audi1]

I couldn't get used to mine and didn't want to listen to what most people was saying that it might not work so i bought a service manual and figured out wiring and put the seats in and tried the bolster button and what surprise the MMI screen popped up displaying the multi contour seat with full function.
now i will be contacting Jack kirry to have him remove CP......

Just curious, how much did you pay for them?

[audi1]

ADVANCE AUTO SALVAGE sells them for around $600.00 each

[audi1]

Well my Multi contour seat retrofit is 100% complete.
Jack kirry is a very very cool guy he work with me 3 nights for over 2 hrs each night to get it done.
we were having issues with my laptop with windows 10 the first night then wifi the second night and today he got it done with laptop with windows 7 that i used.

[RRF985]

Congrats on getting the swap done. Will you be writing a How-to by chance to help others out?

[audi1]

I will be more than happy to help out anyone but i just didn't take pictures or did any write up since i wasn't expecting it to work.
It's not hard to do and you don't have to go to the dealer to remove the CP.

[audi1]

Pic before i got the CP removed..

After i got the CP removed..

I don't have the massage, adjustable seat belt and head rest option so they got deleted which kind sucks cause it looked kinda cool with all of them displayed...

What is CP ?
And why did you remove it, seems that you have more options with it ? :-)

[audi1]

Component Protection.
I didn't remove them, the options that the seats have the car will display.

Interesting. The comfort seats in my S6 have all the options. I didn't realize they made a comfort seat without the massage and other adjustable parts.

[audi1]

Your headrest is motorized? I know my seat belts are motorized and might need to be coded.

[durfA4]

This makes me wonder about the feasibility of adding the A8 seats to my A7. The S7/S6 seats are not available in velvet beige. I could pick up a set of the comfort seats and plug them in. I was thinking about something sport, but all the features seem nice as well.

[gta7]

Well this is awesome news. The dealer quoted me $14k to do the install.

[morski]

As far as im aware the A8 comfort seats fit the A6 as well. Someone over on a german forum iirc has done it

[audi1]

I don't think i would like the A8 seats in my A7 but i definitely will be adding the massage option to my seats soon.
I will do a write up on the wiring when i take it a part again.

[audi1]

Webtoker are your headrest electronic ? i know my seat belts are electronic and might need coding but the headrest are manual no motor.

Na but the bottom of the seat extends out and there is massage functionality along with other features.

[audi1]

Ok. The massage option is the only option that i am missing then cause i have the bottom of the seats that extends and bolster that deflate and inflate when exiting or entering the car.
