Boost-fault diagnosis before parts
Turbocharger Diagnosis & Replacement in South London
Low power, smoke, a boost fault or turbo noise does not automatically mean the turbocharger has failed. SP88 checks control, air, exhaust and lubrication evidence before recommending replacement.

Find the cause before fitting an expensive turbocharger
A boost leak, split hose, vacuum fault, actuator problem, restricted exhaust or oil-supply issue can produce similar symptoms. Replacing the turbo without correcting the cause risks repeat failure.
Boost and air path
Charge hoses, intercooler connections and accessible intake joints are checked for leaks, collapse, oil contamination and poor sealing.
Actuator and control
Vacuum supply, control solenoids, electronic actuators, wastegate or variable-vane behaviour are considered against fault data and commanded boost.
Oil feed and return
Oil level, condition, feed restrictions, return problems and signs of contamination are checked because lubrication faults can damage a replacement.
Related engine and exhaust faults
EGR, DPF, injector, airflow, exhaust-manifold and crankcase-pressure faults may affect boost or contribute to turbo damage.
How the visit works
1. Scan and inspect
SP88 reviews symptoms, fault codes, live information and accessible intake, exhaust and control components.
2. Confirm the repair scope
The vehicle, access, root cause and related parts determine whether diagnosis, an external repair or turbo replacement is appropriate.
3. Replace and commission safely
Where accepted, the correct unit and required ancillary parts are fitted, lubrication procedures are followed and the system is rechecked.
Stop driving if the engine runs on its own oil
Heavy smoke, rapid uncontrolled engine speed, severe oil loss or loud mechanical turbo noise can indicate a serious failure. Switch off safely if possible and arrange recovery rather than continuing to drive.
Diagnosis may be mobile; replacement is often workshop work
Initial fault finding and accessible hose or control repairs may be mobile. Turbo replacement commonly needs secure access, oil and coolant handling, exhaust work and workshop conditions. SP88 confirms the route after inspection.

Questions customers ask
Does an underboost code prove the turbo is faulty?
No. Leaks, sensors, control faults, actuator problems and exhaust restrictions can all affect measured boost.
Can SP88 fit a customer-supplied turbo?
Only after the part, vehicle, cause of failure and required fitting kit are checked. Compatibility is never assumed.
What else may be needed with a replacement?
Depending on the vehicle and failure, oil pipes, seals, gaskets, filters, fluids, hoses or exhaust-related work may be required.
Will SP88 remove emissions equipment?
No. Diagnosis and repair keep required emissions systems in place; this page does not offer DPF, EGR or catalyst removal.
