Do you think I'll be able to find any obvious options or that I'll have to take a look at some long coding?

I measured the outputs on the trailer plug, and I'm getting no voltage on any lights but the blinkers. I assumed theres something with the led lights/ coding since the only lights that didn't need coding were the reverse and blinkers (since they use normal bulbs). I also looked at the westfalia installation instructions (https://www.westfalia-automotive.com/fileadmin/pdf/e_anlagen/305/e305407391101.pdf), adn there si some connecting to the BCM module - so I think it isnt a simple parallel wiring. My bike rack uses PR21 bulbs, which are gonna be hard to get, to try the led bulb thing + I wanna be able to use any normal trailer

Hello, During last winter I retrofitted OEM rear LED lights onto my 2016 Octavia III Combi. I coded them with VCDS, no problem. Now I noticed that the lights on my Thule trailer hitch mount bike rack don't work anymore (the only ones which work are the turn signals). I assume it's a problem with coding, since the bulbs and wiring on the Thule rack are ok and the hitch wiring too. Does anyone have any ideas as to what the problem is? The hitch is an aftermarket Westfalia A40V with a 7 pin socket, which was profesionally installed.

For anyone still looking, here is the part number: 5E9071605SPT It isn't cheap...
