Good to know! I was looking at this particular forum because I need to adjust my left-hand/passenger side headlight aim. It's pointing much lower than the right-hand/driver side headlight. My handbook refers to a "levelling bubble", but that's nowhere to be seen on my car and the handbook instructions do not make sense either. I have attached a photo looking at the rear of the passenger-side headlamp cluster. You can see some sort of adjuster on the right - looks like an intermeshing cog system - may need to turn both at the same time to make the adjustment. Can anyone confirm this before I break something? I assume that the fitting with cables protruding is the electric levelling system that we referred to earlier.
