A lot of comments here lead me to believe that for some they have not been adjusted correctly. Like all headlights they have two adjustment screw's per side, one vertical and one horizontal. I posted a diagram of these elsewhere.
My suspicion is that these are not checked at the dealer as they should be at the price (pre delivery inspection).
You are spot on, and a lot of the SEAT dealers seem to be crap going by posts on here. It is prob no coincidence that I have a good dealer and my lights are set correct.
