How much does a turbocharger replacement cost in the UK?

Turbocharger replacement cost by car type

Prices include the replacement unit, gaskets, oil change, and fitting. Labour is the main cost driver — access difficulty varies significantly by model.

Prices are approximate UK averages. Costs vary by unit quality, access difficulty, and whether additional work (intake cleaning, intercooler flush) is needed.

Warning signs of a failing turbocharger

• ⚠Whistling or whining noise from the engine bay that changes with revs
• ⚠Blue or grey smoke from the exhaust, particularly on acceleration
• ⚠Significantly reduced power and flat acceleration above 2,000 rpm
• ⚠Engine management light or boost pressure warning illuminated
• ⚠Limp mode: car drives slowly and does not respond to throttle above 2,000 rpm
• ⚠Increased oil consumption without visible external leak
• ⚠Oil in the intercooler or intake pipes (indicates turbo seal failure)
• ⚠Burning or oily smell from the engine bay

What affects the price?

New vs remanufactured vs reconditioned

OEM new turbos cost the most (often £500 to £1,500 just for the part) but are the safest for newer or high-performance cars. Remanufactured units from reputable brands (Garrett, BorgWarner) offer OEM-equivalent performance at roughly half the cost. Reconditioned units vary widely in quality.

Variable geometry vs fixed turbos

Variable geometry turbines (VGT), common on diesel cars, have adjustable vanes that allow the turbo to operate efficiently across a wider rev range. These are more expensive than fixed turbos and can sometimes be cleaned and rebuilt when the vanes stick, rather than requiring full replacement.

Location and access

Turbos at the front of the engine in accessible positions (common on many transverse-engine cars) take 3 to 5 hours to replace. Turbos mounted low on the exhaust manifold or requiring partial engine removal can take 8 to 14 hours.

Additional work required

Always includes an oil change. If the intercooler is contaminated with oil from the failed turbo, cleaning or replacing it adds £100 to £400. Blocked oil feed lines (often the root cause of turbo failure) add another £50 to £150.

Common questions about turbocharger replacement

What are the warning signs of a failing turbocharger?

Common warning signs include: a whistling or whining noise from the engine bay that changes with engine revs; excessive grey or blue-tinged smoke from the exhaust, particularly on acceleration or when the throttle is released; significantly reduced power and acceleration (the car feels flat, especially above 2,000 rpm); the check engine light or boost pressure warning illuminating; oil consumption increasing without a visible leak; and an oily, burning smell from the engine. An actuator fault (where the wastegate or variable vane mechanism sticks) can cause limp mode without the turbo itself being mechanically damaged.

What causes a turbocharger to fail?

The most common cause of turbocharger failure is oil starvation or oil contamination. The turbo shaft spins at up to 200,000 rpm and relies entirely on clean oil for lubrication. If the oil is dirty, degraded, or the oil supply is interrupted (due to a blocked oil feed line or a failing oil pump), the shaft bearings fail rapidly. Other common causes include: foreign object ingestion (a piece of debris from the air filter sucked into the compressor side); detonation or pre-ignition on petrol engines; heat soak after hard driving followed by immediately switching off the engine without idling down; and coolant contamination from a head gasket leak. Many turbos fail because the underlying cause is not fixed before fitting a replacement.

Should I replace with a new, remanufactured, or reconditioned turbo?

New OEM turbos are the most expensive option and typically only justified on newer cars or high-performance applications. Remanufactured turbos (fully stripped, worn components replaced with new, tested) from reputable suppliers (such as BorgWarner, Garrett, Turbo International) offer OEM-equivalent performance with a warranty, typically at 50 to 70% of OEM cost. Reconditioned turbos (cleaned and repaired without necessarily replacing all worn components) are cheaper but carry more risk and typically come with a shorter warranty. Avoid unknown-origin turbos with no provenance — a failed replacement will cost more than the saving.

Can a turbocharger be repaired rather than replaced?

Yes, turbocharger specialist workshops can rebuild and repair turbos. A rebuild involves stripping the turbo, replacing worn shaft bearings (CHRA — Centre Housing Rotating Assembly), seals, and any damaged compressor or turbine blades. A specialist rebuild can cost £150 to £500 depending on the size and complexity of the unit, compared to £300 to £800 for a replacement unit. However, if the compressor housing, turbine housing, or shaft itself is damaged, a rebuild is not viable and replacement is needed. Getting the core (your original unit) rebuilt is often cheaper than a replacement if the damage is limited to bearings and seals.

Does fixing the turbo fix the underlying cause?

Not automatically. If the turbo failed due to oil starvation, the oil feed line must be checked, cleaned, or replaced before fitting a new unit. If the turbo ingested debris, the air filter, intercooler, and intake system must be checked and cleaned. If the turbo failed due to a head gasket leak contaminating oil with coolant, the head gasket must be repaired first. A reputable garage will diagnose the root cause and advise on what needs fixing alongside the turbo. Fitting a new turbo without addressing the root cause will result in the replacement failing within months.

Can I drive with a failing turbocharger?

A car can often drive in limp mode with a failing turbo (reduced power, flat acceleration) for a short period, but continuing to drive risks: complete turbo failure with metal debris entering the engine, causing terminal engine damage; oil being forced into the intake and combustion chamber, causing catastrophic engine failure (hydraulic lock if enough oil enters a cylinder); and, on some cars, overfuelling without boost causing damage to injectors or the catalytic converter. If blue or grey smoke is visible, the car should not be driven to avoid engine damage. Limp mode with a turbo fault should be diagnosed urgently.

How long does a turbocharger replacement take?

A straightforward turbocharger replacement on a common diesel hatchback takes 3 to 6 hours at a specialist garage. This includes removing the turbo (which involves disconnecting oil feed and return lines, coolant lines, intake and exhaust connections, and heat shielding), fitting the replacement, priming the new unit with oil before starting, and running the engine to check for leaks and correct boost pressure. On cars where the turbo is buried deep in the engine bay (such as some rear-mounted turbos or those requiring partial engine removal), the job can take 8 to 12 hours.

What is included in a turbocharger replacement?

A complete turbocharger replacement should include: the new or remanufactured turbo unit; replacement gaskets and seals for all connections; a new oil feed banjo bolt or feed pipe filter (often blocked on failed units); an oil and filter change (essential — the failed turbo may have contaminated the oil with metal debris); and a check of the intercooler and intake system for debris or oil contamination. Some garages will also recommend replacing the oil feed line if it is restricted. Always ask what the quote includes — a quoted price that omits the oil change, new gaskets, or intake check is likely to cause problems.

How can I extend the life of a new turbocharger?

Turbocharger longevity is almost entirely dependent on oil quality and oil change frequency. Use the correct grade of engine oil for the car (always check the owner manual or garage recommendation) and change it at or before the manufacturer intervals — for turbocharged cars, shorter intervals (e.g. every 7,500 miles instead of 10,000+) are advisable. Avoid switching off the engine immediately after hard or high-speed driving — idle for 1 to 2 minutes to allow the turbo to cool and oil to circulate. Avoid revving a cold engine hard before oil has reached full operating temperature. Address any oil leaks promptly.
