Quick answer: Replacing the engine in a Peugeot 508 Diesel is a major repair, so the page should answer more than 'how much?'. You need to know which engine variants exist, what can go wrong with them, what evidence to request from a supplier and how the engine will be matched and installed.
What normally causes a Peugeot 508 Diesel engine to be replaced?
Reasons a Peugeot 508 Diesel owner may reach the replacement stage include loss of compression, heavy crankcase pressure, persistent oil consumption, low oil pressure, internal knocking, turbo failure that has contaminated the engine, or serious damage following overheating or timing failure.
If the body, gearbox, suspension and electronics are generally sound, engine replacement can preserve a vehicle you already know. If the car also needs major gearbox, rust or electrical work, the total repair can become harder to justify. Use the fitted quote as part of that wider decision.
Which engines were fitted to the Peugeot 508 Diesel?
Diesel versions commonly use DV4/DV6 1.4/1.6 HDi or DW10/DW12 2.0/2.2 HDi/BlueHDi families depending on model and generation. For Peugeot 508 Diesel, the exact family still depends on model year, output and market specification, so use these as realistic UK examples rather than a substitute for the engine code.
For example, a 1.6 HDi/DV6 engine needs different checks from a 2.0 HDi/DW10, while later PureTech petrol engines have a completely different timing and lubrication profile.
What should you inspect on a used Peugeot 508 Diesel engine?
On DV6 engines, injector-seal carbon and turbo oil-feed cleanliness are important; on later diesels review EGR/DPF and AdBlue history where fitted. Exact engine code and emissions generation should be matched.
Use those points to question the donor engine rather than to assume your original Peugeot 508 Diesel failed in the same way. The fitting garage still needs to establish the cause of the first engine's failure.
A used engine can be a sensible way to keep Peugeot 508 Diesel on the road when the chassis, gearbox and body are still in good order. Correct engine-code matching is the first step before comparing prices.
How do you make sure the replacement engine is compatible?
Treat engine capacity as a starting point, not proof of compatibility. On Peugeot 508 Diesel, the exact code determines details such as ECU calibration, injectors, turbo, emissions equipment and sometimes the block or cylinder head itself.
The donor engine is only half the repair. The workshop should identify whether oil starvation, overheating, turbo debris, fuelling or emissions-system faults contributed to the original Peugeot 508 Diesel failure before commissioning the replacement.
What evidence should come with a used Peugeot 508 Diesel engine?
A meaningful used-engine description should cover donor mileage/history where available, visible damage or leaks, oil/coolant condition, compression or running checks if performed, and what ancillaries are included. Photographs of the actual unit are preferable to stock images.
What does a used Peugeot 508 Diesel engine cost in the UK?
The price of a used Peugeot 508 Diesel engine moves with the exact code, scarcity, donor mileage/condition, whether ancillaries are included and whether you want supply only or a fitted package. Delivery, fluids, timing parts and recovery can change the final bill.
In suitable cases, independent engine supply and fitting may be up to 40% less than some main-dealer replacement routes. The real saving depends on engine availability, labour and what each written quote includes.
Should you choose supply only, fitting or recovery?
Choose the service around what is already arranged. If a garage has diagnosed Peugeot 508 Diesel and is ready to fit, engine-only supply may work well; if the vehicle is stranded, compare recovery and fitting at the same time.
A written warranty should identify the covered engine, start date, duration, claim process and installation conditions. Selected used engines may be offered with up to 6 months cover, subject to supplier terms.
Why compare Peugeot 508 Diesel engines through Engines4Sale?
One accurate enquiry can save repeated phone calls. Engines4Sale uses the Peugeot 508 Diesel details to connect the requirement with relevant engine suppliers and garages serving mainland UK.
A useful Peugeot 508 Diesel quote should identify the proposed engine, what is included with it, the fitting labour, VAT/delivery, recovery if required and the written warranty. That makes different offers genuinely comparable.
A low-cost donor engine is poor value if the old fault is left in place. Make sure the installer has a plan to verify cooling, lubrication and fuelling before returning Peugeot 508 Diesel to normal use.
