Claim:
1. A method for operating a fuel injection device of an internal combustion engine of a motor vehicle, comprising: conveying fuel under pressure into a high-pressure reservoir; controlling the pressure in the high-pressure reservoir with the aid of a pressure regulation; and supplying fuel from the high-pressure reservoir for injection via at least one fuel injection valve under the control of a control device; wherein a control pressure deviation of the pressure in the high-pressure reservoir is detected and the existence of a balance disturbance between quantity of fuel supplied to the high-pressure reservoir and quantity of fuel taken from the high-pressure reservoir is determined from the control pressure deviation, and, if a balance disturbance exists, at least one of (i) an operational influencing of the fuel injection device, which influencing counteracts the balance disturbance, is provided, and (ii) a report of the balance disturbance is generated, wherein:
