make that a 10000s x5 driver with self level suspension, mine turned on when i turn the car on and right away i drove it with -15C outside. After that never showed up again

what ended up happening? i purchased my 06 4.8is a few months ago also and am now having the same problem. replaced the module and code goes away for a bit then comes back. stealer had it for over a week, supposedly spoke with the boys in germany about it and came up with replacing the whole system other than bags. no warranty and am looking at big bucks but its not certain this will fix problem.. please let me know how you guys did and what your issues were. thanks,aj
