edit: see my next post; it seems MB USA specifies spark plug and engine air filter change at 5 yrs/50k miles.

BTW, 37K is only about 23,000 miles. In the US the recommendation for both spark plugs and transmission is 50,000 miles or about 80,000 km.
Remember Mercedes recommendations are not only ultra conservative but also profit driven!
My $.02 and hope this helps.

Most lubricant will degrade overtime, sealed or not. The automotive tranny is not a 100% sealed system. Most transmission has a vent to atmosphere on it because without it, the tranny would basically explode as it warmed up.The fluid has to expand as it warms. This also exposes the ATF to a small degree of moisture from the outside air which may cause contamination overtime. Also, modern day transmissions are design for shift comfort, that means a slower clutch which produce more metal shavings. Changing the transmission fluid and filter will remove the shavings.

Keep in mind most cars other than German cars, have no changing of transmission fluids or at 100,000 miles.
I do not understand why German cars do not use the same fluids, transmission and brake, etc. , that American and Asian cars use. I would save the buyer a lot of money:
OH: of course I understand: every time the buyer spends money, the dealer makes money?

Think about this: Mercedes cost more than almost every car, their parts cost more but they have you believing that in spite of this, their parts last 1/3 or 1/2 as long!
The Mercedes schedule of maintenance is nothing more than an additional revenue stream for Mercedes.

If the oil pump fails, not changing your spark plugs will not void your warranty.
For a warranty claim to be denied, Mercedes must show that the failure was the direct result of a spark plug failure.
One of the first signs of the need to change spark plugs are;
- Hard starting
- rough idling
- decrease in mpg
Mercedes spark plugs cost double that. One would think that paying double would give you twice the length of service. But no, you only get 1/2 the length of service.
Many years ago, before fuel injection, emission controls and gasoline without present day additives, changing spark plugs every 20/30,000 was necessary.
Pull a spark plug at 50,000 miles from todays clean burning engines and they will often look like new.
Another factor to consider, how frequently someone should change fluids, etc is driving style: peddle to the metal or driving Miss Daisy and everything in between. In reality, all of this shouldn't be only based on mileage but also somehow include RPMs divided by miles (total number of revolutions the engine crankshaft makes over a certain distance).
The dealers and us (as owners and prospective buyers) need to hold some type of common standard to ensure vehicles that get returned from leases, traded in, or sold to a 3rd party has some type of accepted scheduled maintenance history that protects the vehicle in the worst case scenario on the bell curve (spirited driver).

I have been leasing for over 40 years, my first lease was on a 1982 Mercedes 300 Turbodiesel.
Back then the leases were structured in such a way that almost 100% were turned in at lease end. Knowing this, and wanting to have the most marketable used cars for resale, Mercedes covered the entire cost of maintenance! Ditto for BMW!
My how things have changed!

And what was the schedule like back then during those first 3 yrs of ownership vs the A, B, A we all know now?

However Mercedes used very soft brake pads. Back then black wheels were very common. 10 to 12,000 miles were all you got. Mercedes claimed soft brakes pads were necessary.
Then Mercedes stopped but BMW started offering free maintenance for 3 years.
Mercedes followed suit: Guess what happened to the brake pads: When Mercedes had to cover them, they changed and brake pads lasted 30 to 40,000 miles.
Beyond changing the oil every 10,000 miles and air filters every 20,000 miles, most of the maintenance on the Mercedes is purely profit driven.
