My battery went dead in my 88 735i. I recharged it and now the radio will not take the correct code. Also the blinking anti-theft light does not work when the ignition is off. Turn the key and radio on, the light blinks, but when I put the code in, it just rings and the word code remains. I have had the battery go bad before, but I have never had this problem. I checked fuses and wires. Everything seems OK.
Any help would be appreciated. Bill
