2007 Mercedes E350 4Matic Sedan W272 Engine/Exhaust

Hello everyone, this is my first post. I have been working on this car with my son as it was given to us. We have fixed the misfires with new plugs and ignition coils. We have fixed the Intake Manifold flap lever. We have cleaned the fuel injectors and run some seafoam through it. We still have to replace the MAF as the code comes up and says it is faulty. My issue now is 2-fold.

First there is a clicking noise coming from the Engine which I am not entirely sure is the Fuel Injection and need a second set of eyes/ears to verify. Second the car still smokes quite a bit from the exhaust, this could be old gas as we are not sure how long it was sitting. (we have added 5 gallons of premium to flush out the seafoam after the first run. If someone more experienced could have a listen/look at the videos it would be greatly appreciated.

Exhaust
Clicking
Thank You

We have replaced the MAF and right now no codes are coming up with the OBD scanner.

Thanks
