In case any of you run into the same issue as me where the adjustor cogs for the headlight end up falling off and getting lost. There is an option to obtain replacements cogs as the adjustor set-up is the same as the facelift E39.
This Ebay seller is selling the cogs as part of a kit. Installed today and it works again, which is a relief!
