I picked up my "new" Pajero last Friday - 2008 GLX diesel LWB

I tried out the CD player with the first time this morning, and found it's not loading the CD's at all. An error code 3 comes up on the display, which as far as I can gather is a mechanism error.
Does anyone know of a quick fix or am I better off taking it back to the dealer to sort out?
Regards
Jaco
