2018 Ocean. Parked on the drive and locked it after cleaning out interior. Pater on noticed lights around sink unit were flashing. Turned them off my opening then locking the van. A while later they were flashing again. This carried on for some time until I eventually went to bed. Next morning the lights were still on, though not flashing. Tried starting the engine, but didn’t even turn over. Assumed the battery was flat so tried jump leads, but still nothing. Then noticed that the glow plug light was flashing, which apparently indicates an engine management issue. Any thoughts on this? Having followed advice from this group about secure parking, it will be difficult to get the van towed off the drive.
