I have a A4 2.5 tdi quattro sport 2001 on the newer shape. I have a problem with my hazard warning lights that i can't fix and ran out of idears. You press the switch and nothing happens. I have changed the switch and did not solve. Both indcators work normally. If you press the button on the key fob they go on and off as they should. I can't find a fuse gone in the fuse box or one marked up for them. I have no wiring diagram that i can use to check or find the relay.I need hep as i need to fix this so my car will pass its mot.
