Engine shuts down

from what i read on this same site the problem id the crankshaft position sensor,but what dO I know I am only on this site becuase I am contemplating buying an e320 4matic wagon

My experience is problem with crank sensor . Drive your car suddly engine quit . Wait for while engine start again .change the crank sensor by ourself is very cheep can buy it in any auto part store..... Located deep behind by blind spot but you can do it . Go to google will show you where is it. Just try. Good luck.
