LED’s not illuminating on light switch

[Matt268uk]

Hey everyone.
I have in my A3 the led that would normally light up green when you turn on your side lights has stopped coming on, actually it’s more intermittent but off more than on. Can I take this apart, clean and generally have a fiddle or has it had it and needs replacing ?

Thanks in advance.

Mine does the same thing. If you pay closer attention you will notice its the road bumps that make it come off or on. Would bet that its a bad solder joint and it just need sto be resoldered. I belive u can take it apart, once you pull the whole switch unit out, it has 3 screws on the back and then it comes out in layers i belive.

I have had this before. You will need to remove the back cover of the knob part (where the connectors go - small torx screws) and resolder the SMD LEDs (if they are still working of course)

Thank you guys for your help. The diagram showing the led’s is great. I’ve had it apart several times but couldn’t really see anything but now I’ll just realised and see what happens.

I took mine apart yesterday, everything looked perfectly fine, but i still reflowed the side lights LED joint and so far its workin fine, full brightness all the time.
