I took delivery of a new 09 C300 couple of days back and it has approximately 200 miles on it now. This morning when i tried to start it didn't start on the first try, but then started up after some hesitation on the second one. I have check engine light on now which is a big turn off for me.

I'm planning to call the dealer, but was wondering if anyone had similar experience or know what it could possibly be?

Talked to the dealer and got a pritty standard response to bring it in and we'll look into it :-/

Sorry to read about this. Hopefully it is just a hickup and not a real problem.

I kinda know the feeling, although I at least had mine a few weeks instead of a couple days. I kinda makes you wonder if you made a mistake. Mine turned out to be nothing and I am loving the car three months on.
Best of Luck and hopefully it is indeed something simple.

The CEL went off after couple of starts during the day today.
Do you think it is a good idea to get it checked out by the dealer anyways? I think it may be a waste since they wouldn't be able to tell what went wrong without the CEL being on. Let me know your thoughts.

There's a log file on the in-car computer that they will look at to see what the problem was. Get it checked now before the situation worsens.

Have it checked. The OBD code should be stored, indicating the cause.

I took the car in and it turned out that the crankshift sensor needs to be replaced.
I'm very disappointed, especially about the fact that it happened so soon.
Anyone knows if this is an easy replacement or will they need to take out a few things from the engine to get to it?

The CEL on my car was going on and off intermittently. This happened about 4 times over a period of about 3 months. I had the problem fixed when I took the car in for its 20,000 km. service.

The work order reads:-

"20001 Electrical short to Camshaft Adjuster, SDS tested and checked for codes, Note codes 0060 and 0061 for R/F Exhaust and Intake Cam Adjusters, Checked actual values, Electrical tested for 6.5 volts return voltage from Adjuster to ME Control Unit, Replaced both R/S Cam Adjusters"

I am not sure exactly what the above means but the engine light has remained off. The engine also seems to be running a lot smoother.

They will probably tell you to bring it in if it happens again which is the standard answer. Or, they will plug it in and pull the stored codes to ID it and decide if anything should be replaced.

Try not to get all upset about it.

It's not that difficult. And it IS something that needs to be taken care of. No reason for long-term concern.

They replaced the sensor and I have my car back now.
Hope I don't have to make another trip to the dealer until another 12,800 miles.
