So, I got a rebuilt intake manifold and had my auto shop done the install few day ago.

After the first install, my shop said I had provided a bad gasket so bank 1 / 3 were misfiring after installing the rebuilt intake manifold.
so they ordered the original gaskets from Mercedes and reinstall the intake manifold.

I picked up the car yesterday and the car seem to be running fine, this morning when I start up the car it also started up normally. (now i thought about it, there might have be a low battery power moment, I thought that might be a old battery issue so I didnt think much as i was going to get a new battery)
I drove for about an hour and felt the was running great and all of sudde the engine check light came up.

after I got home i scan the codes and P2015 P0016 / P0017 , I did some research and its been pointing to famous cam shaft issue, however with the intake manifold just replaced and works, I am hoping maybe it would just be a sensor or something



that need to be reset?

I dont understand how to diagnose the problem so if anyone can shine some light would be appreciated.
