Hi All E60 cifus. I just upgraded my E46 to E60 523i 2006 N52 udm. I have all type of warning as mentioned above. One thing I found is it is ok in the morning( maybe the udm rest for at least 6 hours). All the warning gone in the morning in the drive. Once I turn off the engine and restart, it will have all the warning again. I had taken the the udm to bmw, they said the cas and dsc need to need to replace. Can I get some idea from the cifu...thanks.

The last time I had more than one message/warning light, (it was a combination of active steering, airbag plus one other message, I've forgotten what) the real culprit was the battery.
Messages were generated due to an undervoltage.

Have you managed to solve your problem?
All the best with it.

ABS and other problems

the problem still exist even I had new battery in. Fyi. the problems did not appear in the morning or after the engine off for long time. I once drive 800km from Penang to JB and the problem appear only after the engine off and restart. Few workshop had visited suggest ABS control unit replaced it but suggest to use it for as it is ok in the morning.

Any other factors might caused this?
