Over the weekend I have retrofitted MFSW to my 2011 T5.1.
My T5 did not originally have MFSW installed.

The new steering wheel is the newer style one used in the new golf, polo, T6, but not MQB version etc.
My steering wheel is from a 2015 scirocco, has the 1K8 buttons (no cruise control).

I have BCM 7H0 937 087 H which is compatible with cruise control and MFSW.

At the T41 connector to the indicator / cruise / wiper stalks, I connected the following wires:
Pin 9: 12v ( from pin 28, switched 12v supply for cruise control)
Pin 19: LIN bus (to pin 17 BCM)

Coded in VCDS (Centr. Elect > MFSW Installed)
I have confirmed 12v at pin 9.

All buttons work to control head unit (station, volume etc) and MFD.

However, the buttons do not illuminate.

Could it be that the airbag loom, which has a 5 pin connector into the MFSW buttons, is incorrect?
My MFSW loom has a 5 pin connector with only pins 1,2,3 & 5 used.

I have used erwin to view the T5 wiring diagrams and can see the original MFSW would have a 6 pin connector to the buttons, with only 5 pins used:
J453 - Multifunction steering wheel control unit
6 Pin Connector (2011 T5 Transporter)

Code:
1 - 12v
2 - GND
3 - LIN
4 - Horn Plate
5 - Horn Plate?
6 - not used

And I *think* the 1K8 scirocco has a 5 pin connector, with all pins used.

Or im fearing these buttons illumination are controlled by the BCM?

Here is my autoscan:

I notice there is no coding information for the 1K8 buttons?

Hopefully the above makes sense and someone can give some advice on the situation.

Thanks

your mfsw control module doesn't support illumination same as mk5 mfsw module, so you either solder some wires for illumination or replace module
check this

I thought that may be the case, thanks for confirming!
On the T5, is the control module controlled via the BCM, via LIN bus?
On the mk5 there is an actual module under the steering column.

Thanks

I agree with m87a. The button illumination data is sent by LIN. If you want the buttons illuminated, you'll need a 7E0 BCM.
Your coding for the BCM seems to be fine.

My wheel with 7E0 BCM has the coding:

Subsystem 7 - Part No SW: 1K8 959 442 HW: 1K8 959 442
Component: E221__MFL-DC1 H03 0103
Serial number: 27140002547420014516
Coding: A4FFFF

your assumption for the pinout is almost correct.

1 - 12v
2 - GND
3 - LIN
4 - Horn Plate
5 - Cruise control

To summarize the golfgti thread, as it may help others:
1K8 buttons work but will not illuminate.
1K8 buttons can be forced to illuminate by soldering a wire to pin 2 of the 5 pin connector inside the MFSW buttons, but they will then be on all the time (with ignition).

6C0 buttons (6C0 959 442) will work and illuminate:
The 6C0 version C and D buttons have cruise control buttons.
C standard cruise, D adaptive cruise.
Cruise buttons will not work and be redundant, but the other buttons will work fine.

6C0 with no revision letter, do not have cruise and fully work and illuminate.

Thanks
Jas

I suppose one could also consider 2H0 959 442
