Hi. Started a few days ago and can’t work out cause. Switch lights off and rear sliding doors(both) open! No buttons or anything. Switch lights on when ignition off and then switch lights off and rear sliding doors open. It doesn’t matter whether engine running or not,it still happens. Should imagine it’s an ‘earth’ problem but where. Any ideas please gratefully received. It’s on a 2009 Mk 5 grand voyager 2.7d. baffled grandad.......
