YOUR MERCEDES SERVICING EXPLAINED

Wondering what the difference between an A and B Service? Unsure what recommended additional items are or what is considered to be routine maintenance? Let us fill in the gaps for you.

When you bring your Mercedes-Benz to one of our retailers, you can rest assured that you're in good hands. Our team of experts combine unparalleled technical knowledge with a dedication to exceptional customer care. Whether your vehicle requires a standard 'A' service or a more comprehensive 'B' service, we'll make sure that only necessary parts are replaced, and we'll always keep you informed every step of the way with written confirmation of the work performed. Trust us to take care of your vehicle and give you complete peace of mind.

WHAT'S INCLUDED IN YOUR SERVICE?

The service includes a personalised ‘StarView’ video from your vehicle technician outlining details of your vehicle's health check and detailing any required work, no work is ever carried out without customer approval.

Once we receive approval, you'll receive a personalized quotation. The service quotation is composed of two parts: Routine Maintenance, which includes a full inspection and items needed at every service such as an oil/ filter change, and ‘Recommended Additional’ Items*, which are determined by the vehicle's age and mileage. A 'B' service is a little more comprehensive and also includes brake testing and headlamp alignment.

*Recommended Additional Items are needed to follow the Manufacturer’s Recommended Service Schedule. Without them your free Roadside Assistance cover and 30 years perforation and corrosion  warranty will not be renewed.

Pre service check

Prior to your service, we'll conduct a thorough pre-service check to make sure we address any concerns you may have about your Mercedes-Benz. We'll ask if you've noticed anything out of the ordinary with your car, such as strange noises or unusual driving behavior. If you have, we'll make sure to investigate and address those issues during your service to ensure that we fix the problem correctly the first time. If you prefer, you can also provide this information when you book your service online through our convenient MyService booking portal.

Up-to-date Mercedes-Benz service record

When it comes time to sell your car, the service history is an essential aspect to demonstrate that it has been properly maintained. It is also important to check, especially if your car is on finance, whether it is mandatory to service your car with the manufacturer. This will ensure that your car is in top condition and that you can provide potential buyers with a detailed service history, which can increase the value of your car.
