yeah a gt tdi,
Ahh, OK. You might wanna update your sig then!

i put a hid kit
Eeek. Bad, bad idea. You do know these are illegal, doncha?

on there but the yellow inner pods looked rediculous so i bought some white sidelights but they dont stay on for long
But are the new sidelights the same as the old ones? ie, are the new ones a normal tungsten filament bulb but with a blue coating on the glass - or are they actually LEDs? If they are LEDs, then you will need to either wire in a resisitor to the correct value, or disable the 'cold' bulb test with VAG-COM.
