how can i fix my CD player?

I found the following in another forum and it worked for me:

- remove Fuse 31 (Radio) for about 10-15 seconds
(or disconnect your car battery)
- put Fuse 31/battery back again
(now Radio is asking for the CODE - - - -)
- Insert your 4-Digit-KEY-CODE
- CD PLAYER will work again :-)

- Use a LENS-CLEANER-DISK to avoid to get same
Error Message (E11) soon again
(E11 means the laser optic is dirty)
