I could send you my own VCDS but I would need some sort of security as it is the unlimited VIN £570 pro version.
With these vehicles,I always do voltage readings with the load connected as the BCM sends out a fishing voltage and can disable the circuit. Use a very small pin and backprobe the terminal. Don’t pierce the wires as this encourages moisture to enter the cable and is unnecessary (some seal the wire with liquid tape if they are in a rush).
Also what is your BCM (J519) part number?
Look closely at the thread around Robert’s post to see if you can spot any anomalies to your install.
I can’t check on my van as I have removed it all.
Remind me if you also fitted rear LED lights too?
Could you have something still connected at the headlight plug which is feeding the 14v when it shouldn’t, even though you swapped at the BCM plug? The PWM wires out of the BCM (old location prior to moving to 5/6) have they been disconnected from the LED lights completely, or are they still connected in some way to the 14 pin plug?
I have never seen a levelling system not take the headlights down and up when you key on
I have used brand new control modules and second hand ones in the past and they have always taken the lights down and up and self levelled, I always assumed this was a base function of the control unit/firmware and the coding only tweaked or optimised this operation
Any units without basic calibration will show a fault for a couple weeks then clear themselves (I assume it just takes learned values from driving ?)
I would question if you unit/system is actually working ?
This self test of LED light range control system is called "Reference run" and 55 (Headlights Range module) allows for some configuration of this feature via its own adaptations.I have never seen a levelling system not take the headlights down and up when you key on
