You can't get bi-xenons on the a3 mate only normal (low beam) xenons so your golf ones shold be much better 
I did wonder

Driving at night on deserted Cotswold lanes have NEVER been so awesome....
I have noticed something that has worried me though.... half way down the drivers door there is a grease right on the edge, the thing is it looks like it's been put there during manufacturing... I'll be getting the dealer to check it out but if anyone else could check there's over i'd really appreciate it.... Drivers side, below the handle and right on the edge... very strange looking.....
