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

[tigger73]

Well I'm sorry to say that my Mk7 GTI wheel is going to a new home. Be keen to hear how you guys get on. I was pretty convinced that it wasn't going to work without doing some "magic".

I still think it's possible, though I now believe you may have to solder resistors on/off like here in Vortex: VWVortex.com - The Shopping Cart's --Build Thread--

hey james - any joy ?

[dsgwhizza]

if anyone has one in Brisbane , I could help using my spare bench setup for mk6 golf that I could use to adapt the steering wheel to cluster.

I suspect it's to do with vcds coding and changing the gateway or instrument to the the one after p35

My apologies - I got as far as setting up some diagnostics on the Mk7 wheel but I'm now in the US until mid October so won't get a chance to look further into this until I return.

Bump. Any further progress james?

If you had a LINbus and CANbus listening device you could sus it out exactly what messages are being sent out or retransmitted. You could maybe even program an ATmel controller to get it all to work (this is how I have a MFSW in my mk4 golf! custom ATmel chip translating the LINbus wheel button signals to PIONEER signals ) but that would take serious effort.)

Hi mate, Am really interested on having the MK6 mfsw to be fitted in mt MK4 and have the button working with my pioneer ... Have u posted about how to do it or can u provide me with steps
Thanks

Found some additional info for anyone following this thread.

Here are some German guys trying to work it through and then the adapter that has been created by OEMplus but it doesn't have DSG paddle control hooked up

OK I've done a bit of tracing for the Mk6 and Mk7 wiring harness.

Here's the connections on the Mk6 wiring harness:

And for the Mk7 harness the major difference is the connection of the horn and the use of an additional pin on the Yellow connector:

[ATTACH=CONFIG]18507[/ATTACH]

Also the other thing which I really have no idea about is the operation of the control module that the black connector attaches to (which talks to the buttons/paddles). This sits in the bottom of the mk6 wheel but is "hidden" behind the cruise control buttons in the mk7.

Clearly in Mk6 the horn is routed through this module, however on Mk7 it's connected direct to the yellow connector.

The weird thing is that the horn still works without having to rewire anything so I'm still scratching my head.

Unfortunately I don't have any tools to determine what the function of each pin is and to listen in on any comms.

Hey Guys... I got one attempt for you.
I recognized in a PinOut from new Scirocco SW that there are 2 wires for Cruise Control System (german: GRA) although the new Scirocco has its cruise control not directly on the MFSW...
Could some of you guys with the 1k8 Scirocco MFSW and VCDS give it a try to code the cruise control on the SWCM? I think that could be a back door to obtain the button illumination via the wires for Cruise Control....

Not sure I 100% follow. The Scirocco is still based on the Mk6 Golf platform and not Mk7 MQB as I understand it.

Could somebody who owns a 1k8 SW and an old SWCM (1k0 .... CD or CH) try to code type "3" at the 3rd digit (with multifunction with cruise & voice control) and/or code "4" at the 5th digit (with board computer and woth cruise control system (CCS))?
I think the 2 unidentified wires from your sketch (pin 5 at black plug & pin 8 at the yellow plug) are for both cruise control and illumination.



It might be that VW uses this as backdoor to illuminate the steering wheel on old PQ35 based cars (like new scirocco or even Golf MK V & VI)...


It simply does not make sense otherwise to have those wires within the steering wheel as Scirocco uses the conventional steering wheel columns for CCS

Well I found a thread over on vwvortex with the mk6 steering wheel pinout and it's kind of making a little bit of sense now.



So for the yellow connector (F350), pinout as follows:

Pin 3: Airbag
Pin 4: Airbag
Pin 7: Ground
Pin 8: Horn
Pin 9: Lin bus
Pin 10: 12V

For the black connector (J453):

Pin1: GND
Pin2: 12V
Pin3: Lin
Pin4: Horn (in)
Pin5: Horn (out)

The horn signal looks like it may go via Lin as well as its own signal.

Now all I need is the pinout for the Mk7 Steering wheel control unit (black connector) and I should be able to get this sorted....

have you had any luck getting any pin out information for 5 pin connector in the actual steering wheel button cluster? im doing something similar to everyone here, but not as hard.

im trying to use a JoyCon EXC to conver the LIN bus data to USB into my carPC. if this module can interpret any LIN bus signal, then i should be able to sniff the data from the steering wheel control cluster, but i can not perform this if the button module isnt 'on'. ive tried pin 1 as ground, pin 2 as +12v, and pin 3 as LIN data - but i have not had any luck. i can not confirm that the button clusters are even transmitting data after trying several combinations.

any suggestions would be fantastic.

Any updates on this post?

Nah mate. Next time I'm in Canberra James has offered to get a sniffer onto both wheels to get a better idea of what needs to happen. I might be in Canberra in June

The solution as far as I'm aware is to buy a steering wheel for a Jetta or possibly current model Polo GTI that "looks" like a MQB platform wheel but is actually compatible with the "old" electronics. Don't buy a wheel out of a Mk7 Golf and try and install it into a Mk6. It wont work without sticking in some sort of conversion box to change/convert the LIN messages for each button press.

There were a few sellers on ebay selling these Mk7 "look" steering wheels. Otherwise if you install a proper Mk7 wheel you have to be prepared to lose some functionality from the steering wheel controls.
