We changed the battery on my mercedes benz ml 430 and now my radio is asking for a code

SOURCE: Need Radio Code for ML320 Mercedes Benz

The main dealer will supply the code usually for a small charge.
Have a look on line first though because some are offered freely .
You will need the model year and chassis number.

If your lucky the code may have been written down in the manual book and instructions on how to enter the code. If there was no codes you can try 0000 and see if that works which is the default if no security codes were programed.
If that does not work go to www.radio-code.com. I think it's like $9.00 and they can retrieve the codes for you.
Good luck and hope this helps.

You can get the code from any Mercedes dealer around you. Or you can have the code by taking the radio out and take the serial to a radio repair shop and they can get the code from the serial.

AR82.60-P-7502-01A Coding Radio
(MODEL all with CODE (750) Radio Becker Europa 2000 with CODE (751) Radio Becker Grand Prix 2000 with RDS)

1. If the radio is disconnected from the power supply, it is not operational when re-connected. After switching on the ignition and the radio, the readout CODE appears in the display.
2. The code number for the radio is advised to you on the enclosed CODE CARD.
3. To enter the first digit of the code number, you have to continue pressing station button 1 until the correct digit appears in the display. Adopt the same procedure for the second, third and fourth digits.
4. Once you have entered the correct code number with the station buttons 1, 2, 3, 4 and confirmed the entry with the SEEK button (press down), the readout CODE disappears. The radio can now be operated.
5. If you enter a wrong code three times, you must wait 15 minutes before making a new entry. In addition, if 9 incorrect entries are made, the radio will then not operate for 24 hours. During this time the radio and the ignition (terminal 15) must remain switched on.

1. If the radio is disconnected from the power supply, it cannot be operated by simply reconnecting. After switching on the ignition and the radio the word "CODE" appears in the display on the radio.
2. The code number for the radio is given on the enclosed CODE CARD.
3. Enter the code number with the station button, e.g. number 1, station button 1. After entering the first number the word "CODE" disappears and the number entered appears followed by 4 dashes. The next character to be entered flashes. After entering all five numbers, the first character starts flashing again. In this state the code number can be written over as frequently as desired. A correction can be made only by entering the complete code number again.
4. Confirm code number: Press TUNE, AUTO/SEEK or SC button. The radio automatically switches on and indicates the radio station or frequency stored with station button 1.
5. If an incorrect code number is entered and confirmed, the word "CODE" appears again on the display. If an incorrect code is entered three times the word "WAIT" appears on the display and the radio locks up for approx. 10 min. If the code is entered incorrectly three times again the radio locks up again for 10 min. Three more incorrect entries (a total of 9 incorrect attempts) increase the lock-up time to 60 min. Another three incorrect entries lock up the radio for another 60 min. The waiting time runs only when the radio is switched on.

The 2000 Mercedes models all utilize a Shift Interlock, which will only allow the vehicle to be shifted out of Park while the brake is applied. The way this works is that a lock pin holds the shift lever in the Park position until a solenoid is powered by the brake light circuit, pulling the lock pin away from the shift linkage. The wire to the solenoid may come loose, or the brake light switch may fail. If someone tried to remove the vehicle from Park without applying the brake, the end of the lock pin may have become jammed. Try two things: 1) Start the vehicle, put your foot on the brake, and attempt to move the shift lever from Park to Reverse. 2) If you cannot remove the vehicle from Park, are the brake lights coming on? If not, a) replace the 15A fuse for the brake light circuit, and b) try Step 1 again. 3) If you cannot remove the vehicle from Park and the brake lights are coming on normally, locate the interlock solenoid at the shift lever and make sure it is properly connected. When you put your foot on the brake, the solenoid should retract. If it does not, check for 12V at the solenoid when you put your foot on the brake. If you have voltage, replace the solenoid. If you do not have voltage, you have a broken wire between the brake light switch and the solenoid. If the solenoid retracts but you still cannot remove the vehicle from Park, your shift linkage may have become bent at the transmission linkage. Hope that's helpful! :)
