    I can't tell you what the codes mean but I can tell you that you shouldn't drive the car at all until you find out their meaning, or until you've got it to a garage/workshop who can work on the 4wd.

    Once a problem occurs with the 4wd it can very rapidly deteriorate. What might only be a few hundred to several hundred quid now could turn into several thousand pounds worth of serious damage within a few miles.

    Had the same problem last year, failing pump on the Haldex. No use trying to connect to it over the obd interface as the Haldex units can only be diagnosed using their equipment. They don't even appear on the bus otherwise. In my case I got a pump from a Volvo secondhand from Lithuania which is working fine and saved me a fortune.
