Every rebuilt engine supplied through EnginesMarket includes upgraded components designed to address the original failure point - plus a minimum 12-month unlimited-mileage warranty.

Vehicle Value Check
Vehicle Value Check
A typical Peugeot 508 2.0 BlueHDi of 2014-2022 vintage is worth approximately £6,000-£16,000 depending on mileage and condition【INDUSTRY ESTIMATE】. For vehicles worth £6,000-£10,000, a used engine or targeted AdBlue repair typically offers better value than a full rebuilt unit. For vehicles worth over £10,000, a rebuilt engine with updated SCR components justifies the premium via warranty and reliability.
Our Recommendation
Our Recommendation
On a Peugeot 508 2.0 BlueHDi, replacing the AdBlue tank/pump assembly is cost-effective if the engine is otherwise healthy. If the vehicle has exceeded 100,000 miles or shows additional diesel wear signs, a rebuilt DW10FC with updated SCR components offers better long-term reliability.
