well it took a funny turn today, literally took the car for gearbox service this morning, problems remained the same, picked it up, indicator warning lights worked, then stopped after 10 seconds, after that they would randomly stop & start turn by turn ending in them not working at all, so i'm wondering rather than the cluster if it's another unit dragging the i or k bus down, especially after finding the rear 1/4 where the sat nav is full of water again, nothing is powered up but could still be water affecting the bus. looks like a busy day tomorrow!
