Cross Polo 6R Upgrading to BCM Max with Auto light switch

[MaDwArLoCk]

New wire to SB40. Isolate old wire.

Ok. Probably I have to take out dashboard again ‍♂️

So that could be reason to not working High beam?

I don't think that is related. You need to check the relay and its wiring. Verify with (i.e.) multimeter

You mean from T6/6 to relay?

[iichel]

That could be related. I was referring to the climatronic SB40

[MaDwArLoCk]

Ok. I got it.
Tomorrow will do it!

[MaDwArLoCk]

Now i am 99% sure that it's software/coding!
Again it's evening and everything working fine...

Did you measure terminal 75 voltage?

I'm still thinking:

If you had bought a BCM 7E0937090C, we would all be happier right now.

75x terminal works differently on 6R 7L3 and 7L6. (already commented)
You have a 6R 7L3 with a 7H0 BCM for 7L6. (doesn't help)

Now you have a 6R with a long start/stop period... evenings/mornings
Smile, life usually does not offer such fun opportunities.

12.1V
With working engine - 14.2V

So what does it mean for me?

So you connected the T16 from manual AC to T16 of climatronic with the same pin layout?

Maybe first make a list, in detail, what you did (wiring, connectors, vcds, you name it) because I'm not following it anymore.

No, I've got wiring with connectors from Climatronic 2010:

I cut T16 from Climatic and I've connected those wires to wiring from Climatronic (all wire colors match)

Please verify all wiring with the wiring diagrams:

Thank you for the link!
I will check and compare those diagrams!

Can we do something with my "7H0 BCM for 7L6"?
Update firmware?
