Carbon Cleaning – Waterlooville

Carbon build-up is an unavoidable consequence of combustion, and over time it accumulates on intake valves, injectors, EGR valves, and other components, reducing engine efficiency and increasing fuel consumption. Carbon cleaning removes this build-up without the need for dismantling the engine, and the results can be significant on higher-mileage vehicles.

At Collison Motoring Services, we use TerraClean technology, a professional-grade carbon cleaning system trusted by garages and fleets across the UK.

Signs carbon build-up may be affecting your vehicle:

Reduced fuel economy
Rough idling or hesitation
Poor throttle response
Increased emissions
EGR or DPF warning lights

What does TerraClean involve?

TerraClean works by running a highly refined fuel through the engine’s fuel system while it’s running, dissolving carbon deposits as it passes through. It’s a non-invasive process that takes around an hour and requires no disassembly. Many drivers notice an improvement in smoothness and responsiveness immediately after the treatment.

It’s particularly effective before an emissions test, on vehicles with recurring EGR or DPF issues, and as part of a higher-mileage maintenance programme. We carry out TerraClean treatments for drivers from across Waterlooville, Petersfield, Gosport, and beyond. If your vehicle is feeling less responsive than it used to, or fuel economy has dropped without explanation, carbon cleaning is often a cost-effective first step before looking at more involved repairs.

As a Bosch Service network member, a HEVRA-approved EV and hybrid specialist, and an IMI-affiliated garage, we’re independently verified to meet recognised standards across the board. For you, that means confidence in the quality of the work, without having to just take our word for it.
