albert72 0 Report post Posted March 13, 2014 (edited) Any ideas what could cause hazard/emergency lights to stop working. I've already tried replacing the switch but no luck. central locking switch works as well as both indicator lights Edited March 13, 2014 by Tom325 Quote Share this post Link to post Share on other sites
allan 295 Report post Posted March 13, 2014 Have a look on http://www.bmw-planet.com/diagrams/release/en/e46/index.htm wiring it shows the hazard switch is wired into the light switch has four wires, earth, power and two others it should be easy to check over with a meter.
