Engine carbon cleaning and walnut blasting
Carbon build-up is increasingly common in modern direct-injection engines, where deposits can form on intake valves and within the intake system over time. This build-up can affect fuel economy, idle quality, throttle response, engine performance, and overall drivability.
Wellington European offers staged engine detox and carbon cleaning options depending on the level of build-up and what the engine actually needs. Treatment options may include:
Wellington European offers staged engine detox and carbon cleaning options depending on the level of build-up and what the engine actually needs. Treatment options may include:
- Hydrogen carbon cleaning for lighter deposits
- Hydrogen cleaning combined with intake treatment products
- Walnut blasting for heavier carbon build-up
- Combustion area, exhaust and EGR Turbo cleaning
- Full staged treatment for more severe cases
Walnut blasting uses compressed air and fine crushed walnut shell media to safely remove carbon deposits from intake ports and valve surfaces. This is a more involved process that requires careful disassembly and inspection, not a quick spray treatment.
If your vehicle feels sluggish, rough at idle, or is showing signs of intake carbon build-up, this may be worth discussing alongside your next service or inspection.

Battery replacement and charging system checks
Battery problems rarely happen at a convenient time. Slow starting, warning lights, stop-start issues, or a completely flat battery can all point to battery or charging system faults.
Testing comes first, so replacement only happens when genuinely needed. Battery services may include:
Testing comes first, so replacement only happens when genuinely needed. Battery services may include:
- Battery condition testing
- Charging system checks
- Battery replacement
- AGM and stop-start battery replacement
- Battery coding or registration where required
European vehicles in particular often require the correct battery type and, in some cases, electronic registration after installation. Simply swapping in the wrong battery can create avoidable faults.
Quality batteries are used, with fitment carried out properly to suit the vehicle.

Carbon build-up can cause rough idle, higher fuel use, warning lights or a noticeable loss of power. Before any cleaning is booked in, checks and diagnostics are used to confirm whether the process is likely to help.
The cleaning method is chosen to suit your vehicle and it starts with checks to confirm what is appropriate. Stronger cleaning is only used when it is needed and the steps are explained before work begins.
Rhino racks and roof boxes can be supplied and fitted to match your roof setup and what you plan to carry. Mounting points and torque settings are checked during fitting and load limits are shown so you can use the system safely.
Battery replacement is available for stop-start European vehicles. Charging is checked, the correct battery is fitted and coding or registration is completed when your car requires it.
Whether you are with Autosure, Provident, Janssen, or any other major aftermarket mechanical warranty provider, we handle the claim process on-site for you. Our team completes the diagnosis and costings, submits them directly to your provider for approval, and begins repairs as soon as authorisation is received. We manage all the paperwork and keep you fully informed every step of the way.
