My Metris is back at the dealer with a turbo failure and the camshaft issue is still not resolved. I wonder, if there is a relation between the turbo failure and the camshaft issue.
It would be wonderful, if you find the time to post your solution @KnightOwl

Yes this would be an AMAZING time for knightowl to post their found solution. Because I am getting ready to change my crankshaft sensor sunday. If that does not fix my issue I will be taking it to the dealer for a complete diagnosis which costs $300. Money isnt the point as for this is my company vehicle. I just need to find the problem and fix it ASAP!

Well, fella's, here are the results. After taking my "intake camshaft" to the camshaft balance specialist, he couldn't do much more than inspect it for balance and wear, and the camshaft passed all inspections. He said there was no way to check for alignment or if the camshaft slipped. The only way to check was to fork out almost $600 and order one in for comparison. Well, well, when the new one came in, it became evident that these Mercedes camshafts are poorly made. They slip without even showing any signs. Luckily, there are markings that we can aim for on the camshaft itself. (look at the black mark on camshaft and the grove on the flange) No manual shows this or talks about this!! The only way to see if you have a misaligned camshaft is through experience or by comparing it to a new one. I have uploaded 4 images for you fellas, so you can now check your camshafts and see if they are misaligned prior to buying new ones or wasting money potentially on other parts.
Yes, we rebuilt the timing engine overall 3 times. My mechanic even asked me to buy a used engine. Even the $300 dealer inspection wasn't good enough, they had to spend additional time, which almost cost me another $800, and they STILL weren't able to give me honest answers. But I didn't give up because it just made no sense why things were not working properly. This became tooooo personal to give up!
So my two cents, don't waste your money with the dealer. Don't waste your money on camshaft sensors, crank sensors, and magnets. I did all that for you. Instead, quickly take apart the cam cover and check for your camshaft's alignment. They are cheaply made. A bit disappointed with Mercedes's quality, to be honest.
I hope this helps people down the road. 45k is wayyyyyyy too soon to be having these kinds of problems, especially for an expensive brand like Mercedes. God bless you all and thank you to those who have talked to me throughout this troubleshoot. Gave me more hope to continue.

The cam gears are pressed on the cam shafts and then slip over time?

So basically just need to realign them and it should be good to go, am I understanding that right?

No. Please do NOT try to realign. The flanges are pressed in, and once the press fails, it's done. Trust me, I have a professional welding shop, and I thought about tig-ing once I moved everything back into alignment, but that is not wise. The reason is that the weld will throw the balance off. Do not try to jerry-rig this repair. This engine is costly and rare to find used as well. Saving $600 vs risking a 15k engine is not worth it. Replace it if you have alignment issues. Replace the chain and guides while you are at it. You might as well. It's right there, and on average, only $150 for the parts.
While I would not be too worried about balance, I would be concerned about 1) messing up the heat treat, 2) distorting a machined bearing/seal surface, and if modifying a new cam 3) getting the press-fit interface sufficiently clean, given that there's likely a film of oil in there. They aren't making any of it easy with that narrow flange.
It appears to be an entirely assembled camshaft, with separate lobes as well.
