Hi All

Having issues with my drivers side mirror indicator not working for some odd reason. I've tried replacing the housing with a known working unit, and have also confirmed that there is no fault with the LED as they light up with an external battery.

There doesn't appear to be 12v being delivered to the wiring according to a multimeter, I've stripped my door skin apart to inspect and repair any exposed wires on the door wiring harness.

I've been digging around, another suspect may be the window control module. There seem to be a couple on eBay however is not the exact model of what I have. Problem is that I do not have a vag-com to do any form of reprogramming / coding. Can someone confirm if I need coding done if I get a unit with the exact model number, or one that is slightly newer (eg mines a G, I've seen K units for sale on ebay for relatively cheap).

Or has anyone else had the same issue and can point me in the right direction to diag?

Thanks.
