Mr G Posted July 23 Share Posted July 23 Hi guys, Why would both sidelights not work on an A3,2017, non-S Line. Main beam, and high beam work OK, just the sidelights dont work. Could it be fuse? Bulbs look OK on visual inspection. Where is the fuse box and and what number fuse would it be? Thanks. Quote Link to comment Share on other sites More sharing options...
Steve Q Posted July 23 Share Posted July 23 Could be the light switch itself. Id recommend a diagnostic check to see if any fault codes flag up Quote Link to comment Share on other sites More sharing options...
cliffcoggin Posted July 23 Share Posted July 23 If I recall correctly each sidelight has a separate fuse, so the problem is more likely to be the switch. Fuse and fusebox locations will be in the car handbook if such things exist still. Quote Link to comment Share on other sites More sharing options...
Mr G Posted July 23 Author Share Posted July 23 I found the fuse box, but for the life of me couldn't work out which fuses to check. Quote Link to comment Share on other sites More sharing options...
Mr G Posted July 23 Author Share Posted July 23 It's the bulbs in this picture that isn't working (both sides). That is the sidelight bulb, right? Quote Link to comment Share on other sites More sharing options...
Solution Mr G Posted August 22 Author Solution Share Posted August 22 I think I confused myself somewhat, being a total Audi rookie. So the sidelights are apparently the DRL's, and the bulb I was querying is run by some weird switch for rain lighting????? 1 Quote Link to comment Share on other sites More sharing options...
cliffcoggin Posted August 22 Share Posted August 22 So did you get the sidelights to work? I've never heard of rain lighting. Can you explain further? Quote Link to comment Share on other sites More sharing options...

oake Posted August 23 Share Posted August 23 Apparently, the button you've indicated applies only to cars with LED headlights. Quote Link to comment Share on other sites More sharing options...
Mr G Posted August 23 Author Share Posted August 23 Interested, thanks Steve. So do I just put them on during night and rain? Quote Link to comment Share on other sites More sharing options...

I don't have LED headlights, and my button therefore doesn't do anything, so I can't really help you. I just quoted the relevant passage from my handbook. If you have LED headlights, I guess you could experiment to see what they do. 1 Quote Link to comment Share on other sites More sharing options...
