Just re-discovered this message! Did ask the dealer to check on service, but they came back with "within spec". Checked the beam against my garage at a range of about 3m and the driver side was approx 15cm lower than the passenger side. I wondered whether the self-levelling would take out any manual adjustment I add, but gave it a go. matched the 2 levels and added a bit more and tried on the road. Bit too high, so took it back down a bit, Night use is now back to the brilliance & range I was expecting from my experience of my first model. As to the dealer? i very much doubt they even looked at my request, let alone actually do anything about it.
