I've just installed a new MFSW on my Polo 6R Highline MY2010, following the guide posted on here.
The steering and the airbag are recently produced (October 2016), but we are talking about the 6R MFSW.
Unfortunately horn and buttons don't work (they're not even illuminated).
I checked the new wires I installed (+12V and LIN bus) and all is ok.
These are some part numbers:
BCM: 6R0 937 087 D
Steering: 1K8 419 091 BN MFQ
Airbag: 5K0 880 201 AE 81U
Airbag harness loom: 5K0 971 584 D
Buttons control module: 5K0 959 542 C
Because the airbag harness loom I have is specific for Polo produced from 23/07/2012 onward, I changed my slip ring and stalk switch with M.Y. 2014 ones:
- slip ring: 6R0 959 654
- stalk switch: 6R0 953 507 9B9 (without MFA buttons, since they are on the steering)
The problem persists: horn and buttons don't work.
After long searches on ETKA I've noticed that the Buttons control module I have seems wrong:
I have the 5K0 959 542 C, but I should have 5K0 959 542 B, according to ETKA.
This is a picture of the 5K0 959 542 C control module:

They look different!
Do you think that changing the Buttons control module would fix my problem?
Or is the problem somewhere else?
