Hello all. I have ML320 2000 and like quick acceleration so when I push the pedal to the the end (kickdown mode) car goes into "limp" mode (stuck in the second gear 2000 max rev.). after restarting engine everything is OK until pushing accelerator to the end. (BAS/ESP is illuminated all time). Any solutions? I am student 19years old and need right diagnose by all means thanks beforehand

 

Max rev 2000 sound like security mode. Might also be the air mass sensor.
