Immobilizer and Radio Codes

[banjoboy]

I have been the proud owner of a 2004 C220 CDI for just over 2 weeks now. This is my very first Merc and it is the most modern car I have owned!! I understand that if I want to replace the battery I must first access the immobilizer and radio codes. Can someone pleae tell me where I may find these details. I do not have all the manuals for the car - only the main user guide.

Thanks

A 204 car should not need the radio coding, nothing else to set other than memorising the widows and the ESP that will go way once driving, if the radio did require a code then MB will give you the code
