Does the car run ok? If the answer is yes, close the engine cover and walk away....

Probably a good stance to take RichardHumble... It's typical 'new parent syndrome'. Yes it seems to run fine... and I guess that any unplugged sensors would have been recorded on ECU (which would have been spotted when they did the service).

I'm just a parnickety b4rstew4rd.

I think the exhaust flap is vacuum actuated.

Yes, the actuator is vacuum driven, but the point at which it opens is controlled by the ECU driving a solenoid valve.

Well... mine does have a Janspeed... so that theory would fit I guess.

Ah, gotcha.
