Finally, I found and resolved the problem with "Check Engine Light". In my case it was bad PCV Valve / Breather hose (part of emission system), part# A156 010 03 70 ($90.00). In regular maintenance routine, it needs to be changed every 70,000 miles.
Maybe this information will be helpful who have similar problem with M156 6.2 engine
Symptoms:
If the faults codes P0191 P2187 P0451 present, CEL is ON, can be white smoke from exhaust after cold start, no misfiring, engine oil around the PCV Valve, engine oil dipstick popping out, part# A156 010 03 70 must be replaced.
In some cases, it can be the Purge Valve, fault code P0444. Check if it pulsing by holding it, you will fill the vibration if it working good.
Thank you everyone for help!!!

Question: Are we talking about the PCV valve or hole? When searching for part# A156 010 0370, local MB dealer shows Breather pipe for $97.50 So, valve or hose kit?

If CEL returns wash rinse repeat with assistance of a MB Dealer/ Quality Indy to properly triage the CEL. PCV systems on all motors are fairly easy easy to work on, though this looks to be a little more knuckle dragging than most

"Canister, vent valve, sender unit(s), or gas tank neck"
p0456- I had a lose vacuum line around the rear area driver head light... just go over connections and make sure everything is hooked up...
I took it to the dealer with a screen shot from STAR after they did the gas tank warranty work bc it could have been due to a gas cap/tank pressure issue just to make sure their work was solid...
It actually ended up being a vacuum line off the pump behind the drivers head light... it has a black foam filter that goes around it
just put p0456 into the "search this forum" and you will get a bunch of results... one I used to isolate I think was this one:

I am unsure of the differences btw e55/e63 evap systems... perhaps there is, perhaps there isnt a diff

About a year ago, I got the P2187, it's on twice in a couple weeks period and then it's gone. So you got your gas tank replaced under warranty? I found a doc about MB has extended its warranty to 15 years for the E class model year 2003-2009. Has anyone actually get yours done under this kind of warranty? I don't have good relationship with my local MB dealer. Just wondering should I bring mine in to get checked.

Update: Called the dealer and told them it smells like gas inside the cabin, they asked for the vin to verify if the vehicle was eligible for the warranty and it was. Brought her in the next day, asked for a loan and came back the next day to pick her up. Now she has the brand new fuel tank and the CEL was clear. Maybe the headbolts issue will be recalled one day?

Yes, followed your guide, I did find the lose vacum line, reassured it before I brought her to the dealer for the fuel tank. Now the white smoke is gone after the morning cold start. Thanks.
