Lent my car to my dad over the weekend and he was listening to a CD. When i went to take the CD out today it ejected and then because i took so long it went back into the cd player

nothing unusal!

Then pushed the eject button again and nothing. Anyone know if i can reset tis or fix it easily as its a bit of an odd one. Also is this a common thing on the E46?

Thanks for your help in advance
