cd player in boot

well ive had my car 2.0d x type for 8yrs ...with no problems with the radio/cd player and the six stack cd player in the boot. until Saturday !!! my six stack cd player came up on my display CD ERROR so sunday I taken out the cd player from out the boot,   I must say that the cassette that holds the six cds was jammed in and took some ejecting !!    but it did finally eject.... taken off plastic corner covers and slide the front cover across, this I could then see inside the player ? but could not see anything wrong ! so I got my compressor out and gently blew air through the whole of the unit, loads of little fine bits blew out along with something I have not got a clue flew out of the unit?? but what it was I don't know. so I placed the unit back in the boot and connected it up for a test run to see if and how it would play. and to my amazement it played fantastic , with all six cds playing each in turn when selected, plus the cassette ejected no problem, and just to make sure i done this a good few times before fitting back in boot .. so jobs a good un..
