I have a battery drain problem.
Battery is in good condition, but will discharge over a couple of days.
No aftermarket mods fitted. No internal/boot/glove box light remains on.
Scan shows CCCU failure to communicate with both front door module (intermittent)
CCCU is 8Z0. 959 433 AF
Rather than a scattergun approach what are the logical next steps to trace this PITA fault?
