For cars experiencing running problems, this service can even help to clean out parts that you would normally need to replace – including DPF and EGR systems. We are one of the official service centres in the country using state of the art TerraClean™ decarbonising equipment, helping to keep your car running at its best. So book your car in with Auto Diagnostic Services today.

Why is TerraClean™ Different?

As a TerraClean™ agent, we can offer the best engine cleaning service for all our customers. All petrol and diesel engines build up carbon deposits (regardless of driving style) in combustion chambers, exhaust ports, catalytic converters and on lambda sensors over time. This can often be further propelled by poor fuel quality from cheap fuel stations. Not only will this cost you in terms of fuel, but it can cause expensive parts of your engine to seize up – and eventually fail. TerraClean™ is the only system with two stage cleaning to ensure an optimum service. And using highly refined fuel and linking up to one of our specialist machines, we can effectively remove all carbon deposits restoring cars back to their peak performance.


- Increased power
- Increased fuel economy
- Lower emissions (and reduced carbon footprint)
- Restored MPG

- Quieter running
- Smoother running

In addition 

With our ground-breaking TerraClean™ system, we can now deliver both preventative maintenance and problem solving. And with carbon build up being the number one cause of engine failure, TerraClean™ can really help to save you thousands!  Just as an example, a car’s diesel injectors could be £1,200+ to replace (most engines have at least 4 injectors), a Turbo alone could be £750+, and EGR £350+ on average. So our service can help you avoid unnecessary repairs in the long run, and provides incredible value for money when it comes to preventative care for your vehicle.
