I can't see any real reason why they would be built differently? Hopefully someone will know if they are.
I would have thought it would just be the positions of the beams, you can adjust those with a 6mm hex key (both up and down and left and right), although i also believe if you re-calibrate the system with VAG-com on level ground it will sort it out itself.
We discussed it at work before i re-adjusted my lights and the concensus was if you disconnected the position sensor on the LH rear suspension wishbone and then plugged it back in then it would probably re-calibrate itself as well. I haven't tried it so don't quote me
I opted for the Manual adjustment with the hex key for setting height (which was my issue) and it was simple and quick. White does up and down and black does left to right, all you need to do is work out the positions before removal and then set the new lights to the same post installation.
I hope it is this easy or if there is a reason it won't work hopefully someone knows.
Good luck
Sandy
