Within a short driving time there is a distinct smell of burning oil entering the interior, it appears to be thro' the heater/ac. I have opened the bonnet and there is no smell of hot oil. There are no obvious signs of leaking oil eg in the engine bay or on the ground. Are there any similar experiences and resolves?
