Is this the dreaded camshaft noise for the m156? Video included
What say you gentlemen? Do i have the dreaded camshaft adjuster failure noise?
Could i drive the car in this condition or should i flat bed it to my indy?
I have USAA extended warranty.. they should cover this right?

Should i be taking my car to the dealer or my indy for this job?
I wonder if tappets still need to be replaced if correcting the oil level eliminates the noise.

I haven't driven the car in the past 2 days since i heard the noise... Do you think its safe to drive the car around?

I took her for a very careful drive around my neighborhood til i hit 80C and i noticed that the tapping noise was almost gone. I could still hear the tapping sound when giving it some gas from a complete stop. I parked my car in the garage and let it idle for a bit and even revved it up to about 3.5RPMS and it sounded "normal".
WTF? Do i still bring it in to the dealer/indy and try and make a claim or am i going to be turned down because the sound sort of went away? Man, what a headache lol

So I went to the dealer today and after an hour they confirmed that I have the issue. The grounded the vehicle on the spot and ordered 4 camshaft adjusters. We shall see if that is all or if they find more parts to be replaced (tappets) once they remove the valve cover. In my case the CPO covers it.

Previous owner was affected by head bolt issue and bolts were replaced.
15k miles later at 60k I picked up the vehicle and at 61k the camshaft noise started to become very loud.
They replaced camshafts, adjusters and lifters and start to finish took 3 days.
I cannot complain about the service. Do I wish the engine would not have needed any repairs - yes but at least now all the known quirks have been addressed.
