It's not as bad as everyone is posting. I know people with this mod done on mk5s, mk3s and mk2s. Certain Volvos also have this feature. I've never had difficulty telling when a car with this DRL set up is indicating. There is a big difference between the DRL glow and the indicator flash.
Besides, if it works for all North American mk5s then surely VW have it set up well on the car's computer.
