Installation of a Mk7 Multi-Function steering wheel + paddles into a Mk6

[tigger73]

I would first check the steering wheel that you have is not for a Polo GTI or Scirocco. Unless you definitely know that it has come out of a Mk7 Golf R. I have learnt not to take sellers claims as true. It may look the same but underneath it will work completely differently.

The other thing that you could do is find some buttons from a Scirocco or Polo wheel and fit them to your steering wheel. This is probably easier than making a lin-lin converter as the other thing once you've made the little gadget you then have to put it somewhere. There's seriously not a lot of real estate under the new steering wheel to fit something like this.

Anyway I'm likely going to put my steering wheel up for sale as I'm not really prepared to sink extra $ into it with no guarantees that it's going to work - much better to put those $ towards a wheel that is guaranteed to work with my car.

A lin-lin converter would be a useful gadget if you had one as it would allow the Mk7 guys to retrofit a Mk6 wheel (but then they'd lose cruise control capability).

Tiger73: hi. Just started reading your thread - very courageous project indeed! Sounds like you have come full circle, but just for reference here is the wiring diagram for how the horn-plate and the MFSW control module is connected on a mk7
Cheers

Thanks for that Don.

That confirms that mk7 and mk6 wiring are very similar except for how the horn is wired. The Mk6 routes the horn via the black connector so you get the message on LIN whereas the Mk7 just runs the horn direct.

Both mk6 & 7 run 12V, 0V and LIN on the same wires which is why it kind of works. However the commands for most of the buttons are different as the guys from Germany have confirmed which is why some buttons work, some do the wrong function and others don't work at all.

The only thing that is still a little mystery is the operation of black pin5 to Yellow 11 on the Mk7 which is marked as green on your wiring diagram (my harness had a grey wire). It could be for button illumination perhaps but I'm not 100% sure.

Don do you have DSG paddles in your car? I know of a wheel that could be going cheap if you're up for it!!!!

Stay strong for another week tigger. We might yet find a solution. Lots of irons in the fire.

[tigger73]

Hahaha. I don't see any way out of it other than dropping another $100-200 on a new set of buttons which may or may not fit/work.

You'd need something like this: Original VW Golf 7 VII Multifunktion Tasten Komplett 5G0959442 J



Except these ones are for a Mk7 Golf so are identical to what I currently have. You'd need the Polo or Scirocco equivalent plus you'd need to hope they fit

Tiger73: You sure do ask the big questions!! I''m not entirely sure what the green wire from PIN5 (J453) to PIN11 (J527) does. In fact, I suspect that this wire may not be there on a mk7 (notwithstanding what the Wiring Diagram says). Here is PIN-OUT for connector 5k for J453 - notice the glaring absence of a designation on PIN5!!

Best offer that I have had in a long time, but as marcrae19 is insinuating, perseverance in adversity is either the hallmark of a very committed person, or it's a sign of a person that should be committed (to somewhere where there are lots of behavioural therapists)! - As I suspect that you fall into the former category, I will reluctantly decline the offer - but thanks

That is interesting. I guess it's an optional item. Surely they wouldn't put a wire there for no reason.

In the Mk6, pin5 is use to retransmit the horn.... but the horn is also connected into pin4. I've wired it this way to the Mk7 steering wheel also and the horn still works

The reason I got the wheel was because it came up at the right price. I don't mind spending a bit of time to get it working, however it now looks almost certain that I'll probably have to spend half as much again and there's still no guarantees the additional parts are going to fit/work.

It's probably better for someone with a Mk7 to take it off my hands and fit to their car. It's a nice upgrade for someone looking to get some DSG paddles.

That way I can get a complete Polo/Scirocco wheel instead and not have to worry that all the bits are going to fit/work.

hang in there tigger! - https://www.youtube.com/watch?v=WpgIFPBMT30

Nice find marcrae. I have no doubt it can be done, however I still suspect these wheels are all for PQ platform not MQB.

[tigger73]

Well I found out that the buttons from a Polo GTI wheel was going to cost me $600 at the dealer with no guarantees it was going to fit/work and no returns on the part so I've sold the wheel and will go on the hunt for a Polo GTI/Scirocco R/Mk6 GTI or R wheel with paddle shifters.

I'll do some research on the Polo steering wheel as I'm 99% sure that's what the guys in the UK that claim that they have working are using.

[marcrae19]

I hold out hope that someone much smarter than I will figure out how to do this. In the meantime i will keep adding information i find related to the topic.

Here i found this steering wheel control module table. Not sure if it's of any use.

Our Mk7 wheel arrived this week, so I'll try to pull it apart in the next few weeks and do some comparison with the Mk6 wheel in terms of the CAN and LIN traffic.

Awesome James. Does your Mk7 have the volume buttons on the left hand side? Does it have paddle shift? here is mine

[tigger73]

Just don't tell me it was something simple once I've sold my wheel!!!

[jamesatfish]

Awesome James. Does your Mk7 have the volume buttons on the left hand side? Does it have paddle shift? here is mine

Yes to the volume buttons, no to paddle shift - it's from a manual Mk7 Golf R.
