As the subject says, really. My vRS has Xenons but I'm pretty sure that they can be legally higher than they are. I can put up with it, but if a dealer will do it for free then I'll take advantage!

Based in the South East..

I always thought they should level themselves automatically so maybe they can't be adjusted?

They're normally set up at the dealership a bit lower than ideal. Not sure how much it'll cost but ask them to set them at the legal maximum. Mine are so much better now they've done that.

Would have thought it's about half an hour with the Vagcom etc.

I am burying a kitten after I finish typing this.

A quick search brought up this

And a beam setter.
