DSC 4x4 Inactive,
 

Having numerous problems with the X, I keep getting DSC 4x4 inactive, self level suspension inactive, lose power steering, abs and radio. Car has been at BMW over a week now and they are replacing EHC module. They say theres a good chance it wont fix the whole issue. Anyone have any ideas please help, ECH module parts in labor is 1000$...

Correction. It was EHC module, has anyone had these issues?

yes. the stealer reset the computer and blamed the battery on three occasions.

I figured it was the alternator causing these isssues because the faults only came up when driving around town (low voltage) but they tested the alternator and it came out 100%. Im picking the car up today after they replaced the EHC module, praying it solved the issue.

Please let me know how you got on I think it's the alternator !!!
