Internal Engine Treatments

Reduced performance? High Fuel Consumption? High emission levels? Engine in limp home mode? Sticky valves?

Your car could be experiencing a build-up of carbon in the Turbo causing it to seize, or a blockage in the Diesel Particulate Filter or Exhaust Gas Recirculation Valve.

Our treatments can also be used as a preventative measure to prolong the life of your engine and save hundreds of pounds in repair bills in the future.

This is particularly important for low mileage diesel drivers as the DPF doesn’t get chance to regenerate itself – creating a blockage.

But don’t worry, we can help you!

DPF clean

Thorough clean of the Diesel Particulate Filter and Exhaust System:

If the DPF is blocked it will cause a number of issues, including a severe loss of power. This treatment will restore your DPF back to its full efficiency.

EGR clean

Thorough clean of the EGR Valve and associated pipework:

We use this treatment to unseize sticking EGR valves or as a preventative measure to prevent running faults and costly repairs.

Turbo clean

Thorough clean of Turbo Internals and associated pipework:

Excessive carbon build up in your turbo will put your engine into limp home mode. This treatment will prevent and save a clogged turbo from needing replacement.

Petrol Engine Intake clean

Thorough clean of Engine Intake System including Inlet Valves:

Removing harmful carbon deposits from the inside of the Intake system and back of the valves which can cause engine misfires and other issues.

Especially effective on modern direct injection engines.
