Hi Audi experts!

Recently I got an issue with my Audi A3 2014 Sedan Ambition 2.0 TDI. Suddenly, my boot stopped to work. Won't open on remote key, or on the button located on boot lid itself.

Only way to open is manually from inside, through back seats.

I tried to troubleshoot it, but without success. Already tried this:

• Replaced lock mechanism completely (don't ask why...I tried to be mechanic even if I'm electrician)
• Checked all fuses even if I couldn't find exact fuse for boot lock in any manual
• Measured voltage on connector - 12,7 VDC (between brown and white wires)
  • I really don't know purpose of black/yellow wire - any tips here?
• Tried to trace wires to check if any is broken - all good
• Also saw on forum that some of you had an issue with velvet button....I have none in my gloves compartment

Any ideas where to look and what to check else?

Thanks.

Cheers
