Usually your Mercedes dealer can get you a code for a nominal fee. They usually require the s/n off of the radio, and the VIN off of the car.

Check your owner's manual, just to be sure the sticker isn't in there from the original owner.

I have a Pdf of 1999 C280 Owner's Manual, But can be applied for most C-Class cars including AMG Models from 1995-2000 please send me your email so that I can send it to you.

Common problem if your lucky it might be written in your owners manual. I have seen people write it on the housing of the radio itself.Good Luck!

You will need to see the Mercedes dealer unless you are the original owner, in that case the code was given to you with the original new owners paperwork you may find it in the owners manual packet, it would be a small card like a credit card, the code is unique to each car and radio serial number

radio ask for code

mbusa.com , for 2000 year

The only place you can get that is from the dealer.

not possible, You will need to call the dealer and order one

Sounds like you are probably low on fluid. Check for leaks and fill system. Also make sure car is level. I also suggest you get an owners manual as all of it is covered by the book.
