In my case still no answer. Owned the 07 E70 4.8 since new April 07. Now on third battery and get high draining control messages all the time. Had it two days this week now back in. SIB or not they have no answer. Worst car I have ever had. Comes on every 40 minutes during sleep time and pulls big time amps but no reason why. No Bluetooth used, no aftermarket anything. Comfort access, premium stereo, Nav and cold weather package are my options and I lock it each night and keep the key far away. Really wish they had a clue what they are doing. Still think they are made at the old Yugo plant.
