iTrader: ( 0) Battery registration issue Foxwell scanner. Have the NT510 and entering a different AH Value for the replacement battery. Getting the following reason why I cannot change the value: -No communication with IBS or engine electronics. -DME/DDE program status cannot save battery change. -Terminal 15 was not switched on. -Engine running.MAF sensor readings. Doing the charcoal delete since its so warm out. some suggest resetting the computer to have the computer relearn w/ new MAF readings faster. If you still have your old battery - pick up a CTEK 3300 and charge it up, will take about 50 hours but it will be good as new, green 'eye' and everything.
The vehicle is coded with information related to the size of the battery as well as type of battery. Most stock M3s will have a 90ah AGM battery. Recoding is suggested when changing battery size. That said, as long as the battery purchased was an AGM battery, in this case only a reset of the IBS adaptation values would be required.

When they brought the car out to me I noticed the airbag light was on and asked why. They took the car back in to service and 30 minutes later told me that the positive cable was bad and it would cost me $1,000 to get it
