Well, damn! Since my '13 3.5i decided to spring a leak from what appears to be the expansion tank, I decided to drive the '08 over the last couple of weeks as a daily driver. Wife and I decided to keep it as our dog transport vehicle.

But on the way home yesterday, no messages on the OBC, but felt like I was losing power, so pulled over and decided to scan. Got the following:

002B70 DME: Variable intake system activation
0055D0 Message (steering wheel angle, 0xC4) error, receiver VTG, transmitter DSC
00604E RDC: RDC system
006057 RDC: Wheel electronics, rear right
006140 AL: Redundancy comparison, driver's steering angle
006EC4 DSC: steering-angle sensor, adjustment
00A6CF JBE: AUC sensor
00A6F3 CCC-A: Coding data error
00E723 No message (condensation sensor, 0x2D1), receiver integrated automatic heating
00E729 No message (automatic air recirculation control sensor, 0x2D0), receiver integrated

So another litany of errors and on the ISTA/D all show "No" under the Existent column with the exception of the two regarding the RDC. Anyone think that those errors are my actual issue causing yesterday's loss of power? After scanning and clearing (since I couldn't "fix" anything on the side of the road) it drove just fine the rest of the way home and back to work again this morning.

Any help is appreciated!
