That might explain things. I've been happily driving along at night wondering what the problem is as I can see fine. I have a feeling my dealer keeps an eye on this forum though so they probably do check that in the PDI.
The only annoyance with the headlights is that it seems that if I try to do a quick flash (or double flash) when the lights are on, it just rams the main beams on for a second or so instead of just flashing... but that only seems to be over a certain speed. It's enough to turn a friendly gesture of flashing someone into my lane into an aggressive blasting of the headlights as though I'm accusing them of pulling out in front of me.
When I try it parked, it flashes as I would expect.
Good job there's a full screen display that tells me the main beams are on though. I'd never have noticed from the world around me lighting up...
