Asked by Jul 16, 2014 at 12:39 AM about the 1994 Mercedes-Benz SL-Class SL500

Question type: General

1994 Mercedes-Benz SL500 2-Door Convertible, what is the code to use the radio? I just bought the car and I did not the the code. How can I get a code ? If you tell how to use it too....

Second Question: I got a diagnostics test done because engine light is on, the Repair shop said the computer said undetectable code, what does that mean. They have never seen this before! What needs to be fixed. Does it just need resetting? Car runs great at this time.

If you received the owner's manual, it maybe in there. Look for a business size card with a 5 digit code (or the previous owner may have written it down in the manual. Otherwise, if you bought the car through a Mercedes dealer, then call them and give them the VIN# of the car and, assuming it is still the original radio, they can look it up for you. If you bought privately or from a used car dealer then you will probably have to take the car to the Mercedes dealer (so they can identify that you own the car) and they should be able to give it to you. If it is not the original radio, you will have to remove it and get the model # & serial # and give that to the dealer. There is apparently a site that charges you for getting it (radio-code.com/Mercedes), butI know nothing about them or how accurate they may be. (Looks like they charge about $25) Once you get the code, you enter it using the preset station selectors. push selector #1 repeatedly until you reach the first number of the code. The enter the second # on the second selector switch, etc.. When all 5 entered, hit the SC button & radio should come on. Good Luck!
