hi, i'll be happy to help you in anyway i can.
the most common cause for that code is the cam advance magnets on the front of the cylinder heads, i would replace all 4.
if that doesnt take care of it internal balance shaft issues are not uncommon and spendy to repair.
good luck and happy new year
Well wat im worried about is i just used a genric scan tool not the star mercedes code reader again ppl on forms are saying it could be the balance shaft
yes it could be the balance shaft, replace the magnets first.
we dont want it to the balance shaft due to the expense of the repair.
the magnets fix a lot of them
