The CD carrier in the OE multichanger of my 2000 Renault Scenic ha jammed. I've removed the multichanger from the car and taken off the top panel. IThe CD carrier had not engaged on the tongue that is connected to 2 long springs and would have powered the ejector mechanism. When I unscrewed the inner plate so that the tongue could re-engage behing the CD carrier, a small lever, held by a spring, fell out. I can't now find the location for the lowere end of this. Any ideas please?
