If i set a switch for lights on 0, front day lights in bumper work, but rear lights dont. The same happens in auto mode. If i set the switch on xenon lights, rear work aswell. Fact, that rear lights dont work when normal day lights in front do is ileagal in our country not to say unsafe. Can i somehow set rear lights to work if i have a switch on 0?

Yes it is easily changeable with either VCDS or VAS (Skoda's version of it) take it back to the dealer and get them to alter the settings FOC, if they try to charge you then inform them of the legal requirements of your country.

Forgot to say it may even be changeable in your maxidot menu system - but if in doubt then get the dealer to do it.

You can't set this up via Maxidot system. Problem is, my dealer doesn't know if this is possible at all. Do you have any information, how can this be done with a computer connection?

I changed the setting in an Audi A6, the options were for something like, front only or front and rear (think this is the "Scandinavian" setting)

You would either need the dealers VAS system or someone with VCDS, don't be fooled by the dealer saying it can't be done - it can.
