2016 Front sidelight bulbs with Bi-Xenon headlights

[PetrolDave]

While on holiday in south Devon the front nearside sidelight bulb failure warning would show on the Maxidot when the auto headlights turned on.

 

I'm surprised that there's no 'cold monitoring' so the warning only shows when the bulb is turned on.

 

Looking at the circuit diagram from erWin and comparing that with the Leuchte channels in the BCM shows different pin numbers on the BCM for the front sidelights?

 

Can anyone shed some light on which BCM pins and Leuchte channels actually control the front sidelights with Bi-Xenon headlights?

Not only there is no cold monitoring, but in VCDS an intermittent front sidelight failure shows as a rear left side turn signal fault  😒

1 Fault Found:

5898 - Bulb for Rear Left Side Turn Signal 
          B12D0 15 [009] - Open or Short to Plus
          Confirmed - Tested Since Memory Clear

Sounds like VAG have messed up their diagnostics reporting - VCDS just reports what the VAG software says

Further digging into the circuit diagrams show 3 headlight options - Halogen, Bi-Xenon and Bi-Xenon with LED running lights. Choosing the right one shows the pinout is correct!

 

Then looking into the adaptation channels of the BCM shows why a failed front sidelight is reported as rear left turn light - Skoda have got the dataset wrong and the output controlling the front sidelight is attached to Leuchte channels for the rear turn light!
