Giddy I've got a territory. Went to overtake cars when 4wd derated "limp mode. DSC lamp displayed. Engine started smoking heavily like overfueling. I left the vehicle there that night returned in morning removed earth off battery for a few minutes hoping for a reset. After this couldn't even start. Had good power. Almost like a no fuel cranking no fire. I got wagon towed to local garage. They have scanned for faults etc. but sounds like they are running out of ideas.
