Depending on age and when it was last done, brake fluid replacement might be due.
Have the following been done?
spark plugs
transmission oil replacement
engine air filter
If not, those also are needed by 80k miles.

I can perform the engine oil, cabin filter and engine air filter change. The dealer changed the transmission oil last August. So I am wondering whether it necessary to do the maintenance in the Mercedes dealer shop.
I watched the video for the spark plugs replacement and find it's not so easy.




I did mine on the W212 (same engine 276) and could do it w/o removing the intake plenum. I will be doing sisters W166 in two weeks, and I hope it will be about the same. Of course, the plug next to the firewall opposite the air filter is the trickiest one
. I use a socket with a swivel extension (similar to https://www.autozone.com/test-scan-a...ion/454330_0_0) to avoid the socket to stay trapped just in case. NOTE: you want a short swivel extension of the plug near the firewall, there is not much room for a long extension.Trending Topics

Safety inspection performed
Oil and filter changed
Tire(s) balanced/Tires rotated
Drivability performance checked
Brake fluid flushed/changed
Front wiper blades/refills replaced
Anti-theft/keyless remote battery replaced
Emissions inspection performed
Therefore, I think I only need to change the oil and filters.
-Spark plugs (dealer for V8)
-Brake fluid flush
-coolant flush
-tranny fluid drain/replace and filter...include torque converter...dealer doesnt usually do that part!
-front and rear differential oil change
-transfer case oil change
-engine air filters (2 for V8)
-cabin air filters (3)
-Main and Aux battery change (can last up to 8 or 10 years)
-check brakes...rears wear quickly...mine only last 20k miles.
-oil and filter change.
-check serpentine belt
-alignment (dealer. I have tried numerous different shops, even a Mercedes specialty place, and nobody can do alignment except for dealer for my setup for some reason...Airmatic, 4matic, offroad).
-Id also check OBDII for codes...including ones that dont trip light. I just use a cheap FIXD plugin that bluetooths to phone app to retrieve codes.
-airmatic air intake filter change right front behind bumper.
-check all CV boots for cracking
-check spare tire air pressure
-Spark plugs (dealer for V8)
-Brake fluid flush

These engines are showing signs of camshaft adjusters wear, a thicker oil at cold temperatures is not going to help at startup. It may help when warm "if" it takes longer to come down before the next startup. The check valve added after certain serial number should have taken care of the "thin oil".
