MFSW - Golf GTd MkVII + DSG Paddles -- How I Done It --

Totally stuck mfsw all wiring connected
Steering wheel connector wires added to pin 9 & 10 connected to the blue/green cable on the bcm and 12 volt from the light switch.

Nothing working on the wheel would of thought the buttons would of at least illuminated though the light switch

Van is a euro 6 so bcm connection is correct

Any help anyone getting to the point of refitting my old wheel and selling the new one (wheel was bought from t5upgrades so I know it fits
I know it's a daft question but you have fitted a new MFSW / Airbag loom?
 
Euro 6, according to the wiring diagrams should be pin 36 grey/white cable look at *8

Check you've connected to the correct cable behind the switch

Have you coded it?

Buttons only light up when the lights are on so they're switched by the light switch they're done by canbus so if you've not coded the wheel or connected to the correct lin cable then this might be why they don't work.

Thanks I'll try pin 36 on the bcm hopefully that's my problem

I've coded the wheel using OBDeleven which was easy

I connected to the black cable on the light switch which is 12volt

Thanks for the help

Is this still in the white bcm
 
I opened up the connector on the bcm found the grey/white cable connected to that still nothing, will check the light switch connection is correct I connected to the black cable which is showing 12volt , next I'll need to remove the steering wheel and check the voltage there, thanks

Interesting as I am looking at theirs for my 6.1 I will hold off. Is it a case of programming via vcds?

I've coded mine using OBDeleven easy to do and it's saying code accepted, going to test the steering wheel wires sure I'll get it working. My van didn't have a mfsw be so I had to add in two cable from the column connector bit of a pain of a job but everyone does it
 
@Mark72 did you get this sorted in the end? I've got the same setup as you so assumed a wheel from T5 Upgrades (with the two relevant patch wires, airbag loom, correct buttons etc) plus some coding would be job done but sounds like you've had issues..?

Yeah got it sorted thanks I had used a scotch lock on the bcm bad connection wires soldered and all works
 
ok, so you spliced into pin 36 on the BCM in the end (rather than 17) using the scotch lock from pin 10 on the steering wheel? Then pin 9 spliced into to the feed from the lights?
 
It’s all wired and working correctly the problem was I had used a scotch lock connector to the cable on pin 17 bcm but it was a bad connection nothing worked
Removed the scotch lock and connected the wires it’s all working
 
Ah ok, yeh those scotch locks don't have a good reputation. I had to use them on my towbar because it was impossible to crimp or solder into the BCM cables so fingers crossed they stand the test of time. Thanks for your feedback

so there should be 6x wires at the yellow connector, 2x for Airbag and 4x for power and data)

no illumination feed from what i can see, so the switch modules must get the illumination PVM via the LIN Bus.

Hi, I’ve have been chasing my tail for a while now which this. I have a start line with the same wheel as you, have done exactly the same as you and nothing works. The lights do work on the wheel but it ends there. Did you change your BCM or your clock spring? I’ve noticed on mine pin 11 on the T41 connector for the stalks which is supposed to be for the ACC the pin isn’t there . Not sure if a high line clock spring has this in place ???
just not qui sure as where to go from here.
I’ve checked that all the wires are in the correct location in their respective plugs and I know that I have 12 v and Earth to the wheel.

got a pic of what you have?

we needed to send off the Golf MFSW to have the IC Chips in the Golf button modules swapped out for T6 IC chips.

this was due to the Golf and T6 being on different platforms so the golf buttons wouldn't speak to the T6 modules.

when we had the wheel returned it was plug and play.
