What Is the A3 Service in Mercedes Maintenance Schedule?
The A3 service is a maintenance package included in the Mercedes-Benz maintenance schedule. It is typically recommended at a specific mileage or time interval, depending on the vehicle’s model and year.

Professional vs. DIY A3 Service for Your Mercedes
Understanding the options for your Mercedes’ A3 service, from dealership to DIY, is vital for maintaining your vehicle’s performance and value. The A3 service is a significant maintenance milestone that can be approached in different ways, each with its benefits and drawbacks.

While DIY can save on labor costs, it’s crucial to consider the complexity of modern Mercedes vehicles and the potential for errors without proper training.
A basic DIY A3 service kit might include:
– Oil filter: $20-$50
– Air filter: $10-$30
– Brake pads (if needed): $50-$100 per axle
