Symptoms: When driving in mud, sand or off road, the instrument cluster shows that 4MATIC is unavailable, with no fault codes.
Possible cause described: It is not a fault: the transfer case clutch heats up when a lot of front axle torque is needed for a long time. At about 240 °C the system disconnects to protect itself and comes back when it cools to about 160 °C; the message then disappears (information LI28.00-N-079097).
Check for the garage: Let it cool down: if the message goes away by itself, this is the case.
