i have a 1994 audi 80 coupe,my indicators are the problem when i put them on all of the indicators come on? ive changed the indicator stalk/hazzard switch/fuses/bulbs/flasher unit? but nothing still does it,i just cant seem to work out why they are doing this

so any one has any ideas please give me a shout as its doing my head in now

 

Is the Hazard flasher unit separate from the indicator flasher unit?
They always used to be years ago but don't know when Audi or others started to use a combined electronic unit.

If it still is separate, then the Hazard flasher or Wiring from it may be the source of crossover between left and right.

.

 

i looked for a seperate unit but couldn't find 1 so i think it was 1 unit with the switch

 

Put the hazard flashers on and find the ticking..

 

Or an earth problem? Clean up the ground terminals.

 

yep done that changed the flasher unit still the same,everything else works perfect its just the indicators so i dont think its a bad earth

 

Have you changed the hazard switch??? These should have the gubbins inside like A4's etc of same age, sounds like a relay problem

 

yep changed everything still the same

 

I had this problem with my 3dr turned out being the imobilisor

 

yea im starting to look to that way of things maybe my alarm is causing it

 

Sounds like it if everything else is looked at.

Do the indicators just stay lit and not flash like normal then???

If so its got to be the relay, wether its faulty or the alarm wiring that connects to here. Was the relay/hazard switch new or 2nd hand? Any chance it could be the same problem as the first part you replaced?

 

indicators flash like normal but all of them flash lol and everything ive used to test have come off a working car checked before i took them off

 

Ok, if they flash it doesnt sound like sticking relay then.

But the fact they all flash at same time still points to the hazard switch id think or the wiring of the alarm that goes to it aswell. Maybe try a Haynes or that for a wiring diagram and trace thru it. Done anything recently that might have upset wiring behind dash?

 

Towbar fitted?sometimes those fucking scotchlock bullshit things cause probs where they splice into the rear lights.from memory the hazard lights take priority over the main car indicators.hazards should be fed from a permanent live as oppossed to a switched for the indys due to their nature.thing with electrics is u realy need to be there with your tester etc to try different things.you could try disconnecting the hazard relay/fuse and then seeing if the indicators work independantly from it and vice versa,although the hazards should be on all the time iregardless of the ignition switch if there's a fault there as their fed from a permanent live?

 

no i haven't done anything just bought it from a mate spoke to him and he said it was doing it now and again when he had it but now,its doing it all the time, ive got some wiring diagrams now so ill start tracing the wiring,if comes to the worse and i cant sort it ill just wire the indicators on seperate switches lol
