Hi
My driver side wing mirror indicator light does not work at all, not with hazard light either.
No error message.

 

Does anyone know how to find out if this is due to led/lamp malfunction, broken wire, bad connection, etc?
Would be nice to know before I start disassembling the mirror, and/or door (again), buying replacment light, etc...

 

My drivers side just died I bought some led dynamic ones the power connection does not fit so intermittently work. For one I know the original genuine was faulty if new one works. There are some write ups here and also these are the same I believe as the FL Octavia door mirrors. The standard ones are very expensive to buy hence me going dynamic as they cost a lot less for 2. Be careful it’s very brittle for me on a 2011 superb and I broke a few plastic clips.

Some instructions from this site maybe search thread yourself. 

A slight correction to the procedure I described above:

I've just had to do this job on my 2013 Superb Elegance estate, it is a very fiddly procedure:

1. Remove the mirror glass, disconnect the heating element wires.
2. Remove the downlighter bulb.
3. Remove the 2 Torx head machine screws.
4. Remove the 2 Torx head self tapping screw securing the top half of the mirror housing and the two catches, then gently lever up the top half and remove it.
5. Unclip and remove the bottom half, with the repeater light unit still attached.
6. Remove the 2 Torx head self tappers holding the downlighter bulb holder and remove it to expose the screws securing the repeater unit.
7. Remove the 2 Torx head self tappers attaching the repeater unit to the bottom half of the mirror housing and disconnect the wiring block from the light unit.

All the Torx screws are T10.

Replacement is the exact reverse, be careful not to trap the wires leading to the repeater and the heated mirror.

Thanks,
Did your faulty indicator lamp shown up with a message/warning in the dashboard...?

Someone on youtube said his came with a warning.

 

I have bought one lamp now (

As I said, I'm worried that a cable is bruken in the door...

No dash warnings at all. I believe they are not monitored. 
I already had the drivers door loom replaced a few years ago. 

Fixed!
Both the machine screws broke. They were oxidized and stuck (lots of salting of our roads here in Oslo).
One of the clips broke, but the catch still held(!).

All good!

 

Thanks

Glad you got it sorted. I broke one of the small screws once turned the head snapped off. It’s still held in okay despite all the damage the mirror casing etc took.
