Electrical gremlin on boot lights.

Hey all.

A couple weeks ago I posted regarding the inner OSR brake light going out.
Well the next day the fault cleared and it's still working fine.

Now the odd thing was I washed the car the day previous.

Now washing the car again today (I don't drive it a lot), and since driving after I've had the NSR inner indicator fault come up. Stop the car, works fine for a bit then goes again.

Now I presume I've either got a loose connection to the boot lights or water is getting in from washing, pressure washer most likely.


Has anyone had this before or got any suggestions on where to start looking?

Thanks.


Just to add. It's a B8.5 S4 with the LED rears.

Are the lights removed from the panels in the boot lining?

Also isn't the connections are corroded can I just clean corrosion off and use a contact cleaner?

Found one light with a bit of water in and the other showing water passing the foam seal to the boot lid.

They're both drying out currently, connections look clean though.

Can you buy new seals for the LED ones?
For now I'm just going to go over all joints with Vaseline to get me by.
