The car may start again if it is left to cool off, but it may run roughly or have poor performance. Communicating these specific symptoms to your technician can save diagnostic time.Google+

No notice in engine performance difference. However, this marks the first time the engine light came on and it was coded with P0016 (Crank sensor not aligned with the Cam sensor). Seriously considering trading in this car before the problems domino.
OBD reports crankshaft position sensor error. Engine will die and if on the road will start itself with all the seatbelt and other lights you see when first starting up and the the check engine light will come on. There will be 2 errors on the dash, speedtronic, drive to workshop and ESP please visit workshop. This happens even if the cruise control is not being used. If it dies at a stop it will be very hard to start requiring depressing the gas pedal and cranking for some time.
