Hi, I just bought 2005 CLK500 convertible.(W113 engine) I have 2 issues cuurently that I need your help & advise. The first issue, engine won't crank at first attemp but 2nd or 3rd attempt it runs without any issues. I am suspecting crankshaft sensor because, battery and spark plugs has changed a year ago. What can be cause of that issue? Btw, there is NO engine light and code on the dash.

The 2nd issue, when I started it, there is clicking noise coming from command unit or A/C control unit area. It nocking at least 1 minute or so and when I shut off the engine also that sounds come again.

Thanks in advance for your comments.

Are you saying that the engine does not CRANK until the 2nd or 3rd try, or that it doesn't FIRE? There is a difference.

As far as the clicking noise, plan on removing the dash to fix the problem. I wrote a guide on this recently.
