Hi,

I installed the reverse camera kit from carsystems.pl on a new Mk6 GTI as described in various posts on Golf forums. After a few dramas, I've realised the reversing light doesn't work. All fuses are intact and the light comes on when I execute the output tests on the central electronics module with VCDS. In VCDS monitoring mode I can see the module gets the reverse signal from the gear box but the reverse light signal output stays at 0%.

If I turn on the light with the VCDS output test, the badge pops and the camera comes up on the RCD510. The reverse line draws 3 mA so I'm pretty sure the central electronics module didn't notice any loading caused by hooking the camera to the light output.

The rear wiper seems to have a similar problem. The wiper and steering wheel wiper switch all pass VCDS self tests but won't work. I know the rear wiper did work when I got the car but living in Qld, there hasn't been any need to run the wiper for months so I don't know when it stopped working.

I suspect a dodgy central electronics module but am totally confused why the outputs work in test mode but not normal operation. Any ideas or suggestions before I take the car to the dealer?
