hi, you have two options. you can disconnect the negtaive lead on the battery and then hold down the brake pedal for 3-5 seconds. this will reset the ecu and and stop the problem..
or if you open the hood and look in the engine compartment on the left hand side you will see a small retangular fuse box. if you open up your bmw owners manual it will list each fuse and its circuit. take the small green clips and pull the fuse marked exterior auxiliary lights.
this will keeep you from ahving to reset your radio code and having to re-teach the ecu your driving habits etc.
Does it happen to say "CODE" ? Was battery recently disconnected or go dead? Ot's your theft deterrent radio and needs code to be unlocked. Check owners manual for small credit card size card, that has you code and enter it into your radio. If you don't have code, you're going to have to either have BMW or yourself pull radio and provide BMW the serial # off of radio.
TURN OFF RADIO FIRST BEFORE DISCONNECTING THE NEGATIVE BATTERY CABLE BUT.THATS NO GUARANTEE YOU WILL LOSE RADIO CODE I WOULD TRY TO USE A BACK UP MEMORY SAVER YOU PLUG IN THE CIGARETTE LIGHTER BUT NO GOOD IF CAR GOING TO BE DOWN LONG.TIME BECAUSE THE MEMORY SAVER BATTERY WILL GET WEAK YOURE IN TROUBLE.BMW WARNS IF YOU DISCONNECT BATTERY CABLES YOU WOULD LOSE HEATING COOLING CLIMATE CONTROL.YOU ALSO WILL LOSE FUNCTION TO WINDSHIELD WIPERS AND WASHER , CENTRAL LOCKING AND THEFT SYSTEM CONTROL.
you need the anti-theft code for the radio....the radio should safe theft lock or something similiar to deter theft.....unfortunately you will need to pull the radio to get the serial number off the radio and than beg and plead with the dealer to give you the code without paying for it......you may want to check the owners manual for the radio code......some past owners sometimes will write the code in the book......
