C320 Mercedes 2001 After driving a few miles car won't start

The codes are for fuel trim and a crankshaft position sensor. The no-start condition you are describing is common when the crankshaft position sensor is faulty. I would start by having it replaced. Also, just cleaning the sensor may not have fixed it. You may need to replace the mass air flow sensor to remedy the issue completely. In addition, I recommend replacing the engine air filters when you replace the mass air flow sensor to ensure proper function and that the new one stays clean.
