Parasitic drain - Wiring schematics needed for AV unit

Hi all,

Have found a patasitic drain from fuse 49 (15A) which runs all the AV gear in the boot. Some water damage there as expected but nothing I can pinpoint. Pulling the power leads one by one to the AV units doesnt touch the power drain. All of which makes me think the system is going to sleep for some reason.

Hence I need to get access to the ECU and to try and understand what might be waking it all up.
If anyone has any advice - would be greatly appreciated.

Many Thanks

Matt

What year and what motor are we talking about, l322 i think

Have you checked that your display is going to sleep after 16 minutes and that the red LED at your gear shift extinguishes?
Here's a video I did that may help, turned out to be the heater resistor needed changing.

is an L322 2007 Supercharged 4.2

Yes have done complete trace - whole car goes to sleep properly except fuse F49. Am pretty sure it is water ingress into the rear corner. However, I cant seem to isolate where as the whole AV system seems to stay awake rather than go to sleep. Therefore, was thinking it might be the AMP or the ECU. What were peoples thoughts - any help much appreciated
