Mercedes Benz C Class service: key facts

Routine service items

These are the items covered in a standard service. Most garages include oil, oil filter and a basic inspection. The rest are typically checked or replaced on a schedule.

Service itemIntervalTypical cost
Engine oil and filter
Mercedes specifies 12,500 mile intervals with 229.5 spec oil.

 12,500 miles or 1 year
£80–£120
Dealer: £180–£250
Air filter
Replace every 25,000 miles or 2 years. Dirty filter reduces power and increases fuel consumption, particularly on turbocharged variants. Check more frequently in dusty conditions.

Automatic transmission fluid
Mercedes claims 'lifetime fill' but specialists recommend 75,000 mile changes for 7G-Tronic reliability. Old fluid causes harsh shifting and valve body wear. Change filter simultaneously.

Brake fluid
Change every 2 years regardless of mileage. Brake fluid absorbs water over time, reducing boiling point and causing brake fade. Also prevents internal brake system corrosion.
