Is it an Eco with front air shutters? That's the usual P069E code on these.

P0506 (Idle Air Control System RPM lower than expected) - never seen this on a Cruze. The throttle body is the idle air control system, no IAC valve. But it may suggest a large vacuum leak or something causing the idle to surge around (popped valve cover disc/loose intake hose?)

Yes it is the eco model

Yep, look for stuck/smashed front shutters. If you can't repair them, the "fix" for the code is to replace the fuel pump control module in the trunk with one from a LS/LT/LTZ.
