    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.

    i would have suggested a relay at fault!
    but if the relay for your hazards are indeed located in the switch itself as blackquat suggests i personally would get the car scanned with vagcom to pinpoint an area!

    yeah turkster my thoughts excactly, this problem seems so similar to the issue i had with the cupra... and was told to clean the contacts with spray and couldnt believe how cheap the fix was

    but why would the relay be at fault when like stated the indicators work correctly and so does alarm on/off..... im just stating i had nearly the same issue as you and like you i tryed a hazard switch to no difference made and read of google the issue ppl have with vag's and its down to the dust and **** getting into the connections inside the stalk..... the fix was cheap a can of contact cleaner from maplins £3...... you may not have this fault but its very similar to the one i had thats what forums are for to share like minded info just thought its worth a shot.
