Hello,

I've had my 1999 E 300 diesel for almost eight years, but now I am having headaches.

First, for the last three years (but before that, it worked flawlessly), my factory installed 6 disc changer has been working on and off. I usually get "no cd changer." When it does work, it works until there is something hard on the road such as mild pothole and it says "no cd changer." The last time it worked was for around an hour before there was something on the road.

Also, there is a "check engine" display. I'm not sure with this. Could there be something wrong with the fuel injection although everything seems to be operating fine.

Any suggestions would be a great help.

anyway, the CD changer still powers on and I can still remove the CD cassette.

I'm not sure what the problem is.

Do you think that there is a loose connection somewhere on the fiberoptics and if so what would I have to disassemble. I'm pretty convinced it's a loose connection unless someone has a better idea . . . perhaps an easier solution.

Thanks!
