Still bedridden but I had another thought, this might be a clue but only you can tell me, my driveway is on an incline, and the road is on a decline, whenever I've used my Ducato I always reverse up onto driveway, from the position it needs to move from, and it being 4.5ton, and full lock on steering, it does struggle somewhat and most of the time there is a 'really bad stink' (clutch burning?) which kind of smells like a dead rat, I now suspect this could be some sort of clutch alignment issue? Would this cause the other issues?
Just trying to eliminate any/every possibility.
