Hi, the Hazard Warning Switch (Red Triangle) on my A3 is remaining illuminated perminently i.e. it doesn't switch-off after a time delay once the car is locked. If left standing for a couple of days the battery runs flat. Pulling the F25 (40 amp) fuse switches the illumination off - but obviously takes out the rest of the lighting too! All other electrical systems appear to be working fine. Anyone else experienced this, or got any thoughts? Is it likely to be a fault with the switch itself, or maybe the earthing point (E4/E5 in the Haynes diagram)? Thanks!
