Mercedes Service A vs Service B: What's Included and What It Should Cost
17 June 2026 // 5 min read // Peninsular Motors, Crestmead
If you own a Mercedes-Benz, your dash periodically tells you it’s time for “Service A” or “Service B” - and the dealership quote that follows can be an unpleasant surprise. Here’s what those services actually are, and what they should really cost.
Service A - the “minor” service
Service A typically falls around every 25,000 km or 12 months (your car’s ASSYST system calculates the exact timing). It generally includes:
- Synthetic engine oil and filter change (to Mercedes-Benz specification)
- Fluid level checks and corrections across the vehicle
- Tyre pressure check and correction
- Brake component inspection
- Full-vehicle inspection and reset of the maintenance counter
Typical Brisbane dealership price: $500-$700. At Peninsular Motors: from $395 - same specification, genuine-quality parts and oils.
Service B - the “major” service
Service B usually alternates with Service A (roughly every 25,000 km, offset by a year) and adds deeper items:
- Everything in Service A
- Cabin dust/combination filter replacement
- Brake fluid exchange (a genuine safety item, often due at B intervals)
- Additional inspections: steering, suspension, driveline, body and electrical systems
Typical Brisbane dealership price: $800-$1,200. At Peninsular Motors: from $650, with a full itemised quote before we start.
Why the dealer costs more for the same schedule
The service schedule is identical - it’s published by Mercedes-Benz and every qualified workshop follows the same one. What differs is the overhead attached to your invoice: the showroom, the corporate network, the $200+ hourly rate. Factory training and correct parts are non-negotiable; the glass tower is optional.
The part most independents can’t offer
Since Mercedes-Benz abolished paper service books, your service history lives in the factory’s online Digital Service Book (DSB). Only authorised workshops can write to it - and an entry from an authorised independent reads exactly like a dealer entry, protecting your resale value and supporting warranty and goodwill claims.
Peninsular Motors is one of a limited number of independent workshops in Queensland with DSB authorisation. Every Mercedes service we complete is recorded on the factory system - here’s how the Digital Service Book works.
