it probibly doesnt on mine........ i only use the flash when people cut me up or dont move out of my way!!!
it may well be a relay........??
try
vw vortex they have forums i'm on there dont go on very often,
i have tried to go on the other day but it wont send me my password........
but they are pretty good on there....... american petrol heads.............. so i'm sure one of them may know the answer............. worth asking them........ they fixed my vr6 said it was the hall sender when it was drivng slow.... and they were right!!!!!!
they only have technical talk on there....... no vw chat....
so there bit more professional when it comes to problems...........
