2008 ML550 94k miles. CPS going bad?
My 2008 ML550 has started to become hard to start. It used to sporatically (maybe once a day)turn over for 3-4 seconds before starting, but now it's much more frequent. Research has indicated that it could be a camshaft position sensor going bad. My question is this: Will these sensors going bad *always* throw a CEL? ( I have no CEL illuminated) If it doesn't throw the light, will there be a code stored and if not, how can I tell which is bad?

If you live in the US, it will trigger the CEL. If you do not live in the US, there is no guarantee that the CEL will illuminate.
If there is a code, it will probably be the Crankshaft. Position Sensor.
