Our 2016 e63s just gone through this. All 4 camshaft adjustor solenoids (276-156-07-90) replaced at MB under extended warranty.
It is described on invoice for left intake camshaft solenoid required removal of drive belt, drain engine coolant and loosen (not remove) oil filter housing . Hope it helps you in your repair.

Wow the E63 looks the same as the E550. I did not have to remove any parts at all.
I wonder what changed between 2012 and 2014- I can take some photos, but there are two A/C hard lines, the oil filter housing and the charge pipe in the way in my car.
I believe that you are correct to say that 2012 and 2014 are different. 2012 E550, driver's side. Oil filter housing is bottom right.
Notice the AC pipes don't have the bolted connection in the way.
But still tight and required a closed end gearwrench to access bolts.
User @39039 has videos on YouTube, user Senior Leigh, for the M276 engine. Look at his tools, the curved jaw pliers are used to pull the coil boots off. It's still a hard job because the boots adhere to the spark plugs. I posted photos all of my tools for spark plug change on my GLE350 4MATIC Ownership Report thread in the GLE W166 section.
Pittsburgh long reach hose pliers are very handy to pull the connector off the plug.

Correct you need a ratcheting wrench one. 8mm one I believe.
Keep looking at it. If you pull back the wiring harness and remove the oil filter, you will open up more space.
The only screw you can't easily access is the lower/bottom one, correct? If the oil filter is removed, will you have access for a wrench? Another option is to remove the front cylinder head cover with the magnets, as an assembly. Replace and reseal the assembly, then reinstall.
The hard pipe with a black hose is a water pipe. If you remove the rubber, then see if you can remove the metal portion, this will give more space.
I had the wiring harness pulled back- I took those pictures after I buttoned everything back up because I could not access that bottom bolt. I also had the oil filter housing removed.

If that's the driver's side, left solenoid when looking at the engine from the front of the car toward the back, then your car has a ton more space. It's weird how they changed things- might be the difference between the original style and facelift models.
Dont feel bad PA.
One day, I will need to lift up my entire engine for a simple plastic pipe of water heater, coz I worry it will aged and break. Target 2024.
If you mean an E8 ratcheting wrench, no. There isn't enough space to put it over the head of the bolt and if I could, there is no way to unscrew it and have clearance to remove the bolt or the wrench. It's that tight.

That's the passenger side- there's less clearance on the driver's side, but I will see if that works- I never thought to try a regular hex wrench on an E-Torx head. All else fails, I can pull all of the stuff as per the WIS.

It will work the were not too tight on my older motor. Do make sure you get new ones, as they will come with the loctite on the threads. Do not reuse the old ones. The wrench hugs the bolt pretty good.
I replaced my ignition coils today and dropped one of the e8 bolts and cannot locate it. Does anyone have a part number? Looked everyone! Thanks in advance
