Boot won't unlock

Haven't found a simualr situation, so posting up here;

The problem I am having is the boot is completely non-functional. It acts like it is perminantly locked, and does not open via the central locking, remote central locking, boot badge or drivers door switch. IT did this once before, about a month after owning it, but had righted itself the next day and I put it down to a blip as I'd been using the roof so much.

This time, the problem has stayed, so;

Stripped the boot apart and saw corrosion around the data plug for the roof module (plug 3rd from the right as I look at it) and also around the boot latch plug.

22439



Taken both out and cleaned as best as possible with contact cleaner and cotton buds/jewellers screwdriver. Everything reconnected, and the boot did operate for one "rotation" which leads me to think the corrosion is the problem or maybe a broken wire.

Tested the self close motor by pressing in the latch manually and locking the car,and the motor pulls the striker down, unlatch using the manual release on the latch itself, the striker comes back up.

Disconnecting the plug on the latch and the roof module results in movement from the striker depending on if connected/disconnected and position of the latch.

VCDS shows 1 fault, 02805 - System Interference , although the switch on the drivers door shows as operated when pulled and checked on measuring blocks. Full car scan attached (infotainment is currently out of the car for some work)

There is no eletric clunk or noise from the boot when locked/unlocked by any means, however when I close the boot the self close motor pulls it down without a problem, it shows closed on the DIS and when I pull the emergency release it pops up fine, shows open on the DIS as well.

From doing some reading, I think the latch plug has a connection for an electric release, and if so, could be a bad connection? Seems strange its just one pin in the harness though? I have replaced the latch mechanism and still the same, so thats one part eliminated at least.
