Can turning the car off mid drive mess up the air ride suspension of an early 2000s benz?
how could it possibly "mess up" a rubber bellows? you're concerned that shuttin' down the ignition while mid-flite will cause it droopy dog and give you a HARD ride?....just do not shut the air compressor for the air bladders off...that's all~
Sorry you are talking to a complete car novice. So is the answer no you can not mess up the air ride suspension by shutting the car off in mid flight?
there are spring kits~ http://www.carid.com/2000-mercedes-s-class-suspension-systems/arnott-air- suspension-10115642.html
