Ok what long test are you referring to? A draw test..? BMW equipment is more than capable to do an extended draw test and record all results for hours or days if need be. The power management control unit does all of this and keeps running records of all events/ closed circuit infringement violations. So why is BMW going to perform a draw test, waste tech time for something they can see with a scan of the vehicle. And as far as keep locking and unlocking the doors supposed dealer excuse, the control unit that controls these functions is the jbe. I have replaced jbe's before but never for sporadic self locking of even failed locking/unlocking all together. So stop sitting on your keys while sitting on the couch!!!
