A1 Diagnostics provides professional Volkswagen servicing, diagnostics and repairs from our independent garage in Cardiff. From routine oil and filter changes to DSG servicing, engine diagnostics and complex electrical repairs, our technicians can help maintain your Volkswagen’s reliability, performance and safety.

Volkswagen produces a broad range of petrol, diesel, hybrid and electric vehicles. Each model can have different oil specifications, maintenance schedules, transmission requirements and service procedures.

Before completing any work, we identify the vehicle using its registration and check the maintenance items applicable to its model, engine and transmission.

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