I am new to this forum so please pardon me if someone has already answered. I have a 2000 ml320 with 68k and this morning when my wife went to start it the battery was dead. I jumped the car and it started fine... the problem that happened next was that the car would not move? When placed in reverse, the gear engages but the engine will not rev up when I press on the gas peddle. When I put the car back in park in idles up and down by itself. My ESP/BAS light is on as well. I plugged my OBDII computer and found no error codes. Any ideas?
