hi there. i have always noticed that in my 1997 a4 1,8tq, when using my
daytime runners (in Canada) or using the full headlights, there is zero
change in lighting in the headlights. there is no bulb actually even
switching on when the headlights are on as compared to the daytime runners.
if i switch to highbeams, the lights do get brighter - but it really only
seems like the same bulbs are growing brighter - not a separate bulb turning
it wasnt a problem before, but now im going to be buying a xenon kit upgrade
. obviously i need a separate set of leads to power the xenons and cant be
driving around all day with xenons going full blast. if someone knows why my
audi headlight wiring is so messed up please fill me in. im pretty sure it
isnt the bulbs since both sides have the same problem. could it be a fuse i
need to change positions for or something?
Pre-99.5 A4s use low beams as DRLs in Canada, so you wouldn't see a
difference when you switch on your headlights, because they're on all the
time. Newer model A4's (1999.5 and newer) use the lower front foglights as
DRLs. On other cars, they use the high beams at a reduced power for DRLs,
so when you flash your high beams, it gets brighter.
There is a simple way to disable your headlights and just having your
parking lights as DRLs if you don't want to run your Xenons all day. Check
