I have a VW T6.1 , which is a campervan conversion with a pop top roof. This morning as we lay in bed , the ignition spontaneously started and both front door windows opened . The engine didn’t start.The ignition switched off and the windows remained open within a minute. I then switched the ignition on with the key and closed the windows . Then started up the engine and switched it off. Both key fobs were untouched . However we had the pop top roof down overnight due to heavy rain . We put the roof up this morning and could hear a lot of rainwater running off the roof when we did this. Obviously some water had collected on the roof overnight ( the roof has ridges and has a solar panel) The ignition started and the windows opened about within about 1-2 minutes after this . So I’m guessing it was something to do with water ingress from this . Should I do anything about this or just leave it to dry out
