Rovert.....my Maxiscan is a few years old and no longer supported for software updates. It works well on the Rover V8 though. It reads generic faults and you choose the engine maker to get specific codes for that engine. It works by choosing either Rover or Land Rover. I will dig out the model number. I think Sealey were UK distributors for the Autel range. There are others that some people in here use, some being a combo of a phone app and plug in dongle.
