Intake manifold runner control faults...
 

Had these come up a couple weeks ago, CEL was on, not flashing, so wasn't serious...

012600 - Intake Manifold Runner Control: Regulation Deviation
P3138 - 008 - Implausible Signal
008200 - Intake Manifold Flap; Bank 1: Electrical Malfunction
P2008 - 001 - Upper Limit Exceeded

Never seen this fault code before and no mention of it on the forums. Got the dealer to look at it today, basically the intake manifold runner control is fault and needs to be replaced.

Just got this too.
 

Thanks for the info.
