Automatic C5 2010 163hp check engine.

[ThomasH]

I have a problem with my C5, when i do a kickdown, the check engine light comes on with the message “Engine fault: repair needed”. The same happens when I’m driving on the highway or when I overtake somebody. When this happens, the car stops pulling, I need to turn of the engine and back on for the car to pull again, till the check engine light comes on again with the same message. I have checked wit a Delphi diagnosis tool, U2005, U1213, P11AA fault codes show up (U2005 and P11AA shown up as “intermitent” and U1213 as “permanent”. Please help me find a solution, thank you!
