HELP!! 06 jetta tdi brake lights on when ignition is on

Ive been trying to solve this problem for awhile now and just cant get it. Whenever my key is on the brake lights stay on. data list shows brake switch off and reads correctly when operating pedal, swapped ecm, j519 control module, gateway, changed all bulbs, new clutch switch. I dont have a good wiring diagram to test the inputs to the j519 which supplies power to brake lights but unplugging connector c does nothing(brake light switch input). Pulling connectors C or D turn lights off Any help would be appreciated Thanks

Is it a single switch or a 2 in 1? If you disconnect the switch do the lights go off?

I think it might be 2 switches in 1, one side tells the cu and the other works the lights, not a 100% sure though but I'd disconnect the switch and see if they go off.

Only other thing I can think of might be the wrong bulb or bulbs, think they have to be some can bus friendly ones or it can cause weird brake light issues.

I dealt with this on a similar age seat ibiza over here in the UK, I just seem to remember it was something to do with a bulb or bulbs.

i have disconnected each set of brake lights and doesnt change, LED 3rd brake light stays on

Its a 2 in one switch on the brake master cylinder

Even though VW calls it a switch, It's actually a proximity sensor much like a crank position sensor and has no moving parts. It is bolted to the outside of the master cylinder.
