My wife drove the car, a 2007 2.2 diesel, on the highway and experienced engine loss of power.
Stopped and leaved the motor idling.
Started driving again and everything is good.
She called me and I guided her through the Hawkeye Diagnostic that shows last error message is "actuator stucked closed".
Having read a lot about throttle body on the forum and wondering if it might be this.
I am currently working at sea so I can not get checked this myself.
Has anyone experienced the same, the car loses power and then work fine.
It does not come up any engine lights on the dashboard nor any noises from the throttle body.

She phoned me right now and told that in information screen says: reduce engine performance.
Stopped the car and kept it in idle, and everything OK.

Best regards
John
