Something is fishy! To be clear, the headlights are in the down position and you can hear the right retractor motor running when the headlight is down; but, you can only hear this when the ignition switch is in the run position (engine running)? Perhaps
@Heineken can advise whether there is something unique to Euro spec cars; but, on North American spec cars the headlight system is 'HOT AT ALL TIMES' and is unaffected by the position of the ignition switch.
Make absolutely sure that it is the retractor motor that you hear running and not the right side condenser fan motor running which can also be caused by a stuck relay which would match up with key on / key off symptom. So, need some clarity as to what exactly is going on.
If it is definitely the retractor motor and the Euro models have the key on / off provision then you likely need the ETM for the Euro models and perhaps Heineken can help there. If this is not some Euro specific thing then I think a previous owner might have been messing with things. It is also possible that there is a problem with a wiring short of some king that is causing retractor motor power up when the ignition is switched on.
If this were a
North American spec vehicle the likely candidates would be a stuck relay as
@comtec mentions or a problem with the limit / position switches in the retractor motor (or pinched / broken wiring to the limit switches. As comtec also notes, the first easy thing to do would be to pull the right side retractor relay and cut relay. This shows the position of the cut relays in relay box A
These are the retractor relays
Although checking relays is the easy thing to do (so do it first) my bet would be a problem associated with the position switch inside the retractor motor.
The very first thing to resolve is is it actually the retractor motor you hear and if so why the headlight operation is affected be the ignition switch position and whether this is a normal Euro thing or whether it something fishy with the wiring / a previous owner caused problem.
