I have an Audi A4 2.8SE. All 4 indicator lights have stopped working and the indicator lights on the dashboard do not work. Fuses are OK - what else should I check?

Also. the main display shows error messages - I suspect there is a fault in the ABS module because when I physically move the connectors the errors disappear - has anyone else had a problem like this?

 

Check those fuses with an ohm meter.

If wiggling a wire makes a problem come and go, clean the relevant contacts and inspect the wires and connections for cold solder joints.

 

I found the fault - it was a faulty hazard lights warning switch - replaced it and the indicators are now working
