Retrofit memory seats Passat B8

sam1754 · Feb 3, 2020

The new seats are ready with airbag units in backrests. All is ready but I still have to wire confort can bus from driver'seat coupling point to convenience point on A pillar (soldering on door harness) and powering passenger seat. I have bought wires with right colors but I didn't manage to find the right male pins to put in connectors.
Anybody know how to find which type of pin fit in those connectors, please?

I can find out for sure if you give me the connector part number...

GREAT!!!
I need one pin for 4F0937733 --> there is 4 large and 6 small pins. I need a large one to plug electric control for passenger seat adjustement.
And two small ones for 4F0937743 to plug confort CANBUS wires.
Many thanks for your reply!

for 4F0 937 733, get 000 979 242 E at the dealer, or Tyco 968851-1
for 4F0 937 743, get 000 979 020 E at the dealer, or Tyco 963898-1

Great!
I come back from VW's dealer and they just sell repair kit with wire.
I bought N 103 190 05 pins for 2,5mm2
and N 103 360 05 pins for 0,5mm2
Hope it'll come soon... from China

Still waiting for wires... from China. Safety first!

darkchina811 · Mar 2, 2020

that's why I had given you the Tyco part number, you can get everything on Mouser and pins are stupid cheap. of course you need a crimper and need to know how to crimp :P

I wait for the entire harness for rear seats but I already have wires and pins for front seats. But I searched for "Mouser " in France and it's possible. Really great information!!! For the rest, I'll learn (with 100 pins, I can try and break ten or more pins before making good crimping

).

I saw on mouser that "000 979 020 E at the dealer, or Tyco 963898-1" is sold by 17000 units!!! I just need two units...

Then buy the single repair wire at the dealer and be done with it

sam1754 · Mar 4, 2020

No, I'll just wait a few days to receive it from China, it's already in the flight to France :thumbs:

...Ohoho! its in FRANCE!!!

darkchina811 · Mar 6, 2020

17000 is the reel but they also cut it down, I had bought 50 or 100 at different times.

sam1754 · Mar 6, 2020

Yes, I saw it, the pin I was searching for wasn't in stock but you're right, it's stay a good solution to find pins. Thanks

Hello, all hardware is ready (wires and harness recieved/prepared), not already put in the car. I need the car be working everyday!
So, I want to be sure that I'll be able to do all coding/adaptations needed before starting.
I worry about airbags , seat belt tensioners, seat occupied recognition module!!!

AirbagVW20 - Ross-Tech Wiki

wiki.ross-tech.com

New seats come with airbags fitted from the same car, same year (B8 2015 estate). Seat belt tensioners have to be kept.
Any advice, ideas...

sam1754 · Sep 17, 2020

Really no one???
In EU, belt tensioner are in B pillar, so I don't mind. Passenger seat belt seems to be just plug and play, no electronic part. I think airbags have the same impedance. But driver memory controller should make trouble, no???

I believe there's nothing to worry about.

Do you think I have to disconnect the battery or plugs are safe enough?

sam1754 · Dec 2, 2020

Hello!
I'm back with my retrofit.
I had to dismantle nearly all the interior to make the installation as per factory. I had to drive wires behind the dashboard and MY back will remember it for a long time. :eek:

I even used original fuse slot (not dedicated to it) on the panel to power rear seats with T30. I ordered original additional thermal fuse plug for front passenger seat.
I'll post photos.

But after coding AC controller, I can use rear buttons but nothing happens, no heating. MIB doesn't show any consumption for rear seats. I think there's a coding/adaptation issue but where???
PS: I naturally checked +12v behind rear AC panel control

Any help?
It's cold and my children want to have their little butt warm

sam1754 · Dec 2, 2020

Humm...
Just turn engine on...and it works

I think consumption management in MIB is a question of adaptation line...
But the final thing I want to do is enabling control of all seats heating via MIB AC's display.

I havent figured out a way to do that, but if possible i would be interested too since rear passengers often forget to turn off the seat heating...

Seems that controlling the rear seat heaters is not possible but you can lock the controls of the rear panel so that rear passengers don't have the option to change the settings or turn on/off the heaters either. That is done from the MIB in climatronic menu. Just put the rear to lock and all the controls are disabled. Or that how it should be according to manual.
I'm still waiting parts for my rear seat heating retrofit so cannot verify it yet.
