E 430 (Wagon, Touring, 4Matic)Turn key to ON, not run just ON, so all the dash lights are on, press the
O botton twice quickly, like twice in one sec. Service
reset will come on with the little wrench
symbol, immediately turn key to the off position, press the zero button
and hold it in while turning the key to the on position again, hold the
button till it beeps, release button and turn key to off position.
While your in the car anyway do the ecu
reset
and set the learned driver values back to the factory settings,like an
instant tune up in two minutes time... (FSS = Flexible Service System)

Hope help.
