Is solvent flushing safe for seals and sensors?

Yes. We use a non-caustic detergent approved for alloy housings, MAP sensors and turbo seals, while keeping engine temperature within safe limits.

What We Do

Intake & Turbo Cleaning

In-Garage, On-Point

We decarbonise swirl flaps, manifold runners and VNT vanes without removing the turbo.

Sticky soot and oil mist coat the intake manifold and variable-vane turbo over time, starving the engine of air and raising exhaust temps. Our clean uses an engineered solvent flush plus calibrated vane exercise to dissolve carbon, free stuck vanes and restore full boost. Expect livelier acceleration, reduced smoke and lower EGTs in under 90 minutes.

Why Drivers Book Us

Cleaner Intake,

Sharper Boost

Coked-up intake runners and sticky variable-vane turbos steal power, raise exhaust temperature and light the dash with “low boost” faults. Our intake & turbo cleaning clears carbon without removing the turbo, so you feel crisper throttle and stronger mid-range pull in under 90 minutes. Call 07827533529 or book your clean online today.

A gummed-up turbo can’t swing its vanes freely, so boost arrives late and overtakes feel laboured. By flushing solvent through the hot side and exercising the actuator under live data, we free the vanes and restore factory boost curves. Drivers report the car pulls harder from 1 800 rpm and holds gear on motorway inclines that once demanded a downshift.

Left untreated, carbon build-up bakes solid around the turbine, forcing the actuator motor to overwork. That strain burns out gears, triggers limp-mode “P0299 under-boost” codes and eventually calls for a costly turbo replacement. Cleaning before seizure protects the actuator, keeps exhaust temperatures down and extends turbo life.

A clear intake path improves air-fuel mix, lowers soot, and helps the DPF regenerate at the right temperature. Many owners see 2–4 % better mpg on identical commutes and a noticeable cut in black smoke under load. A cleaner burn also reduces NOx, giving you a smoother drive and an easier MOT emissions pass.

Common Boost Issues

Vehicles We Clean Most

for Turbo & Intake Carbon

Variable-vane turbos and direct-injection intakes can carbon-up quickly, especially on low-speed, stop-start routes. These are the cars and vans we’re called to every week to free sticky vanes, de-coke runners and restore factory boost response.

VW Passat 2.0 TDI

Short commutes glaze the VNT vanes; car drops into limp mode with P0299 under-boost until the turbo is flushed clean.

Ford Mondeo 2.0 TDCi

Sticky intake swirl flaps and oily mist bake soot onto the turbo’s hot side, delaying boost and raising EGTs.

Audi A4 2.0 TFSI

Direct-injection petrol leaves heavy valve deposits; manifold runners clog, causing hesitation and rough idle.

Peugeot 3008 1.6 HDi

Low-rpm city use gums up tiny GT15 vanes; actuator overworks and flags “Turbo pressure too low”. Flush restores movement.

Mercedes Sprinter 2.1 CDI

Delivery-van idling never reaches burn-off temps, so the VNT seizes and the van struggles to hold sixth on motorway climbs.

Vauxhall Astra 1.9 CDTi

Oil mist from the breather coats the boost sensor and intake runners, triggering low-boost and smoke under load.

Why It Matters

Free-Flow Intake,
Healthy Turbo

Remove carbon before boost—and your wallet—suffers

When carbon bakes onto variable-vane turbos and intake runners, the vanes stick, boost arrives late and exhaust temperatures soar. Left untouched, the actuator strains until P0299 under-boost or P2263 performance faults appear—and a replacement turbo is four figures. Our solvent flush breaks down deposits, frees the vanes and clears the runners, restoring factory airflow in under 90 minutes on your driveway.

FAQ’s

Have Questions About Intake & Turbo Cleaning?

Real Answers Before We Flush the Carbon

What is intake & turbo cleaning?

We feed an engineered solvent through the intake runners and variable-vane turbo while exercising the actuator. The fluid dissolves carbon on vanes, manifold ports and swirl flaps, then we rinse and log live boost to confirm full movement—no turbo removal needed.

How do I know my turbo vanes are sticking?

Late boost, flat spots from 1 500–2 000 rpm, P0299 or P2263 under-boost codes, and higher-than-normal exhaust-gas temperatures all point to carbon-gummed vanes or intake restriction.

Will solvent flushing damage seals or sensors?

No. We use a manufacturer-approved, non-caustic detergent that won’t harm alloy housings, MAP sensors or turbo seals. The engine is idled at controlled rpm so temperatures stay within safe limits.

How long does a mobile intake & turbo clean take?

Most cars and light vans are finished in 60–90 minutes, including pre-flush diagnostics, solvent soak, vane exercise and post-flush boost logging.

What gains will I feel after cleaning?

Expect faster spool, stronger mid-range pull and steadier cruise boost. Many drivers notice smoother acceleration, reduced black smoke and 2–4 % better fuel economy on identical routes.

How much does professional intake & turbo cleaning cost?

Pricing ranges from £150 to £220 depending on engine size and access. That’s far less than replacing a seized turbo or removing the manifold for manual decoke.

Can cleaning the turbo prolong DPF life?

Yes. Free-moving vanes lower exhaust back-pressure and temperature, helping the DPF regenerate at the correct interval and preventing soot from baking into ash.

Does the service affect MOT emissions?

A cleaner burn and restored boost improve combustion efficiency, usually reducing smoke opacity and NOx—both checked in the MOT. Many owners book the clean just before their test for extra peace of mind.
