WE ARE A MERCEDES INDEPENDENT SPECIALIST

Mercedes-Benz Vehicle Servicing Cardiff

A1 Diagnostics provides professional Mercedes-Benz servicing, diagnostics and repairs from our independent garage in Cardiff. From scheduled maintenance and oil services to automatic gearbox servicing, electrical fault diagnosis and control-module programming, our technicians can help maintain your Mercedes-Benz.

Mercedes-Benz vehicles combine sophisticated engines, transmissions, safety systems, electronics and driver-assistance technology. Servicing should therefore be based on the precise model, engine, mileage and maintenance information displayed by the vehicle.

Before completing any work, we identify the vehicle using its registration and check whether it requires Service A, Service B or additional model-specific maintenance.

Our workshop is located on Sloper Road near Cardiff City Stadium, serving Mercedes-Benz owners from Leckwith, Canton, Grangetown, Riverside, Ely, Fairwater and communities throughout Cardiff and South Wales.
