CEL's for Throttle actuator popped up early in the week on my '11 X5D. Throttle flap seemed operational. Regen wouldn't run, per Carly. Had to put some miles on while waiting on the replacement part. Nervously watched the soot mass get up to 44g while waiting for the UPS truck.

Replaced the throttle body w/ OEM from FCP. Not too bad of a task, even for someone with minimal mechanical know-how such as myself. Took my time, and all said and done I think I was 1hr to remove, replace, and button everything back up.

Only oddity was the replacement filister bolts I grabbed were 4mm hex and the originals were 5mm. Same threads, just different heads.

Cleared codes, and I was good to go. Regen kicked back in as soon as I hit the highway!
