Thank you for suck a great tutorial!!!!
Will all buttons work? (especially from the right side)

I'm having a OEM MFSW with buttons only on the left, i'm planning to add the right buttons to it.

On the right side, the OK/up/down buttons should work and depending on your head unit, the voice command button should also work.

- I took the LIN bus from driver's door connector (T28a, pin16), which is more more easy to reach, instead of connector T73b, pin 17.
- I used fast electric connectors instead of soldering.
Can I please request you to share pictures of the Driver's door connector and where exactly to locate it?

Hello

I have read your post about retrofitting a MFSW on a polo base/trendline. In your post you've indacated that:
- A -
Plug in of a repaire wire to pin 9 on the stalk/clock spring and then connecting to 12V (no 15) on my light switch to illuminate the buttons on the wheel, and...
- B -
Plug another wire to pin 10 on the stalk/clock spring and running it to the BCM, no 17. And then running pin out from 20 & 21 to the stereo/radio deck before programming the MFSW on the BCM via VCDS.

Problem:
I have a Polo Vivo base/trendline (2011- picture attached ) looks similar to Polo 9N3. My BCM model number is 6q2937049f.

Point -A- I followed the process but it doesn't work at all 😢 (illuminate the buttons). I have tested and confirmed that there's power in the wire (pin 9) to the stalk but it doesn't work. Q: Does it not perhaps require a seperate/additional wire to ground it or to 'circulate current'? Does illumination require VCDS programming to work? If so how/why as it this connection does not run via BCM. 👀

Point -B- my BCM looks different to your example, and only has pins 1 to 18 with multiple open slots.

How do I at least resolve point -A-? Before I can even think of -B-

I would highly appreciate your assistance in regard. 🙏🏾😭

Thank you

You're in the 6r section but that's the wrong place for your question

Lol someone here may advise on the right steps. VW family doesn't and shouldn't discriminate based on the variant 😅

Besides I just to know if only no 15 is enough to illuminate the buttons or if I need an extra connection
