I know this has been covered before but just wanted to tell sonmeone
When going round a corner my indicators suddenly stopped working.
I suspected the relay so I called Audi dealer for a price and it turns out they are £50
After a few choices words I decided my first port of call was to search on here for causes and solutions.
I found a great post by DEV about the relay and how to access it and repair it.
I proceeded to remove the radio, climate control and ashtray.
This allowed me to get to the offending part.
So instead of simple relays, turns out it is a small box of electronics.
Opening the box I found a single circuit board with 2 surface mount relays and lots of other bits, resistors etc.
I assumed the smaller one was the indicators and the larger one the hazards.
Next was to pop down to Maplins to find a compatible part. The one I ended up with is in the pic below.
I proceeded to de-solder the small relay from the circuit board as shown below
Now the new relay is bigger than the old one and a slightly different pin configuration.
So I decided to solder new wires to the points on the circuit board where the old relay used to be and mount it outside the box as shown below. (wiring colours are just random)
As you can see I also drilled a hole in the box for the wires to go through.
I then simply soldered the wires onto the new relay as below.
Feeling pretty chuffed with myself I plugged it back in the car and turned on the ignition, only to get a horrible buzzing noise from the new relay.
After removing it from the car and a bit of head scratching I reversed the wires on the relay switch (wires 3 and 4 shown below), which is the only 2 I could see I could have gotten wrong and plugged it back into car. HEY PRESTO, I have indicators again!!!
Obviously I cannot say how long they will last but fingers crossed it does the job for now.
