I’ve just bought a new Headlight and I’m just wondering if it’ll need recoding since it’s Xenon’s. Car is a Leon Mk3 2014 and the Headlight part number is 5F2941007
 
Are you planning on swapping the control modules over?
 
If they are new modules then they will need programming, you *might* get away with it if they're used but could end up with certain errors depending on the equipment installed on the vehicle.

Either way, you could do with carrying out basic settings on them once everything is fitted.
