Rely on our experienced technicians

With over 17 years of experience in the business, Tony Simpson Ltd takes pride in using the most up-to-date diagnostic equipment, which is unique among specialist garages in the North East, which also allows us to apply dealer level diagnostics.

We have an excellent team of four highly trained and experienced technicians to diagnose your vehicle. We can identify and assess a whole range of problems which may adversely affect the normal running conditions.

Once the diagnosing is complete, we’ll fix your vehicle to perfection, ensuring long life and durability for years to come.

How do we work?

With the use of electronic control units (ECUs) in vehicles, the task of vehicle diagnostics has become more technical and accurate. By using ECUs, technicians can take advantage of computer technology to aid them in identifying and resolving malfunctions. Virtually all modern vehicles now come equipped with on board diagnostics (OBD) ports, which allow technicians to access the ECU data.

We also specialise in MOT testing and complete servicing of your vehicle, irrespective of the make and model. Our services are spread across County Durham and surrounding areas. Contact us today to book an appointment.
