I drive 428i from 2014 with bi-xenon and adaptive lights (lighting package). After I changed the left xenon plug (the cover fixer was broken) I get the following issues on the LEFT side (right xenon is still fully functioning):

Works:
- Xenon low beam
- Blinker
- Fog + cornering lights

Does not work:
- Xenon high beam
- DLR/AHL (rings) off
- Adaptive headlights (+ dash error)
- No up/down light check-up at start-up

Everything worked ok before the plug swap. I rechecked the wiring (via pictures, numbers), cleaned the connections, re-seated the fuses, even put the old plug back – the symptoms/dash errors are the same.

Current issues? AHL module? stepper motors? short circuit?

The car is US import to Europe hence I do not have a warranty anymore… :-(

Thanks for you help
