I seem to have a slight leak on the rear n/s back window, it has stopped the satnav from working and the dash display has changed colour. I`ve been advised to wrap my electrics in plastic bags which I`ve done , once I`ve stopped the leak do you think there is any chance of drying the area out and restoring everything, regards Barrie.

Depends how bad the water ingress, you will need to remove all units and where able open up and clean all the boards, brake fluid is good

Then get some Pcb protection spray once spotless and checked and seal them for future protection

Items in the boot are plug and play so you can replace with others if found to be toast  Current vehicles

Posted in the wrong section - unless you're just bought an L405

and its 'ingress' - searching on that will give you a few threads like this one

Thanks for putting right,
