4x4! Malfunction


I recently purchased an '07 X5 4.8i. It now has 90,000 miles on it, and this past weekend while attempting to climb a friends long icy driveway, I got the 4x4! Malfunction warning on the nav screen. I have the Autoenguity scanner, but the codes it retrieved were apparently not codes it recognized as it simply said 'unknown dtc description'. They were:


I have an older version of the ISTA/D software and it indicates that the first code is supposedly "Driver Seat Occupancy Detector Error". If this is true, I suspect it's coincidental, as I wouldn't think it would inhibit the xDrive system.

The second code it ISTA/D had no information on. The third code came back as "Transfer Case Malfunction".

Does anyone have a newer version of DIS that would be willing to lookup the codes for me to confirm what they are, and if possible print the service plan from DIS so I know what to look for? I suspect the problem is the infamous transfer case actuator gear failure. But it would be nice to have a better idea before pulling it apart.

Many Thanks!

The other place to start checking is the battery - when they start to go in the E70 all sorts of faults start appearing (though in your case it sounds like more of a "real" issue as the 4x4 system was fully engaged)....I'd still see what the date on the battery is regardless as that will throw all sorts of codes as it fails.
The journey is the destination....
