On the car in question, version 110cv, ? was disconnected with the engine off and battery connected to the mass air flow sensor, for maintenance. From the next restart of the engine is for? the message "injection - control", together with the yellow light with the wrench. The car runs for? normally. I wanted to ask if in your experience ? an error destined to disappear alone, though ? disposable with a detachment of the battery or in some way with a generic software and a reader obd elm327. Thanks.
