Camshaft adjuster slapping noise
I'm not sure if this noise is coming from the camshaft adjuster or not.
I had to take out the cam adjusters to do the lifters.
Is this the sound of a cam adjuster failing or maybe a botched install of the cam adjuster?

that's your adjuster. sounds almost like its trying to adjust but not able to. mine doesn't sound like that. mine has a steady tick which is normal if not brand new.
what oil are you running? i'd recommend Motul Xcess 8100 5w-30 with LiquiMoly MoS2 if you aren't and see if that helps. some brands of oil cause the M156 to run louder and adjusters to become noiser than others.

it could be...is it actually logging a misfire? cam phasing can cause misfire at low RPMs in general. haven't experienced it myself on these engines though to be certain. what is your mileage? do you know if the adjusters have been replaced?

It’s not logging a misfire but the count increases at 1200rpm on cyl 7 ( which is the same bank as the adjuster ) .
i also never had this noise before I got the lifters and headbolts changed . Could removing the adjuster somehow have damaged it ? I put in new cam bolts to
is it possible to unplug the cam adjuster and stop it from working to diagnose or will it throw a code / go into limp mode

what are the correct values for part throttle 10% , 1300RPM cruise ? My right intake is 18', Left intake is 18'. left exhaust changes from -13 to to 0 but sometimes spikes to +14.5 , right exhaust stays at about -5 to -7'
Perhaps this left exhaust cam is causing my low rpm misfire?
At idle, the right intake is 28.1', left intake is 27.6' (spec26 to 30)
Right Exhaust is -14', Left exhaust is -15.6 (spec -13 to -17)
Older mercs could have the cam position sensor disconnected and it would not engage the cam adjuster. Just wondering I disconnected the intake cam position sensors and/or the exhaust cam position sensors if the car would still drive?

I am having the same problem.
I believe is the oil control rings on the cam adjuster spocket.
I found mine broken.
replacing them in a few days, this should allow the cams to build pressure to adjust the timing.
i also had misfire at low rpm.
