Indicator Relay Repaired

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 :eek::mad::eek:
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!!! :D:D:D
Obviously I cannot say how long they will last but fingers crossed it does the job for now.

Thread resurrection!!
with these relays getting more expensive (£60) and potentially harder to buy new the above fix is surely the way to go!!
Does anyone know the correct relay as above as struggling to find a match or indeed know exactly what i am looking for???
cheers

Wow thats a great find!!
Is that a direct replacment?
£12 postage is a little ott unless a group buy could be arranged??
 
The G8N-1 is a direct replacement, according to the photo in the original post. Beware of other variants with suffixes.
A lot cheaper than £60 though, which is your only alternative! Mouser also have the other Omron relay in stock, so you could effectively have a new assembly for less than half the price.

Wonder if it is worth phoning their UK office in High Wycombe and asking about shipping. - Andy
 
Have emailed them will await there reply!
Looking on ebay if you have time on your side they can be had for under £8
Ebay no. 113732154385
 
Little update as intend to find a fix for under a fiver!
To buy me time have a good second hand unit coming from Clackers, (many thanks)
Have bought the ebay direct fit but this may take some weeks to arrive!
Contacted RS components, they have discontinued the exact fit but do a similar (but not direct fit to pcb) rs part number 815-6592 and JSM1-12V-5 its a Panasonic item costs £1.60 and i believe the pins are in the same place as original so in theory would be a simple case of wiring to match the pcb mount, i say simple but not sure which amperage wiring i should use?? (This is based on the pictured indicator relay as i am aware there are 2 types)
 
With quality to match, I suspect. You might need more than one!

I don't need any though I wouldn't be surprised if the £7 unit @Howey purchased was the same quality. Cheap Chinese products are often of comparable quality to more expensive UK supplied products (from China).

In my experience, anything Chinese AND cheap, normally has a short lifespan.

Tried to wire my relay but struggled to get old relay from pcb, happened to be passing an auto electrics chap i know and left it with him
Upon testing still no indicators but hazards still working. Checked fuses in bottom corner of dash, all ok. Opened the box up and the way i see it he has got 4 and 3 mixed up with each other and 2 and 5 mixed up with each other??
If anyone has any thoughts that would be greatly appreciated!!!
