2002 Range Rover Vogue 4.4 V8 Java Black

L322 Dipped Beam Failure

Click image to enlarge

Hi. 2002 V8 petrol L322 fitted with 2006 headlights.
I had an intermittent offside dipped beam failure which is now a permanent failure.
I’ve changed the bulb, the ballast, the lights switch with no success.
Does anyone know which terminal to volt test on the 16 pin plug?
There doesn’t appear to be a fuse for the dipped beam either.
Any advice appreciated.

Thanks
PFA

So, after testing it appears I have no power on the dip beam wire.
I don’t know what to check now as there appears to be no fuse 🤷🏼
Any advice very much appreciated.

On a 2002 it'll be BMW electronics. The BMW light control module or LCM maintains a series of counters for short circuits, bulb failures and so on. If the counters reach a certain threshold the LCM disables the power feed to the circuit or circuits affected. The counters can only be reset using diagnostics, which on a BMW would be done with Tool32 from the BMW Standard Tools.

I'd start there - I've never tried BMW diagnostics on a RR but I'd guess they may work against the BMW shared modules.
