2009 cl63 humming noise and hesitant.
Hi.
Have an 09 cl63 that I purchased recently.
It's started making the humming noise which I think might be the abc pulsation damper.
However the car also has a slight hesitation and throws up the following codes.
P0025-left camshaft incorrect position
P0040-o2 sensors wrongly connected
P0356-ignition coil of cylinder 6. Value alternates between too high and low
And p2101- throttle valve position not defined.
From the first camshaft code I'm not sure if I need to change the camshaft sensors or is there any magnet on this engines like used in the c class.
Anyone face anything like this or any idea if all these codes are related.
Thanks

Humming is probably the abc pulsation dampner. Mine was annoying mostly between 2-2.5k rpm. It took 3 different dealers to figure mine out, not sure how you nailed it so quick. 
Sorry Im useless on your other issues
