Hi, I have a B4 Passat and the manual says that the day time running lights are at a dimmer setting and when you turn on the main lights they will get brighter. That is not the case with mine. Is it possible the dimmer is not functioning or are my lights staying dim at all times. I had purchaced aftermarket 100w bulbs that don't seem to be as bright as you would think they would be. Does any one have any suggestions on what the problem could be and how to fix it?
Thanks,
Fabio
