Root cause
High-pressure piezo injectors degrade internally, causing poor atomisation, rough idle, and excessive fuel consumption.
Repair options & estimated costs (UK ranges)
| Repair tier | Dealer price | Specialist price | What it involves | Longevity / suitability |
|---|---|---|---|---|
| Minor - Single Injector Replacement | £450 - £750 | £295 - £495 | Replace one faulty injector with reconditioned unit, code to ECU | Temporary fix; other injectors likely to follow within 12 months |
| Intermediate - Full Injector Set | £1,200 - £1,950 | £795 - £1,350 | Replace all four injectors with reconditioned units, full coding and calibration | Restores performance; viable if engine otherwise healthy under £1,500 car value |
| Full Replacement - Rebuilt K9K Engine | £1,800 - £3,200 | £495 - £1,450 + fitting | Supply & fit rebuilt engine with upgraded injectors, bench-tested, 12-month warranty | Best value for high-mileage Logans; avoids cascading component failures |
Our recommendation
On a Logan valued under £1,500, injector repair costs often exceed the car's worth. A rebuilt K9K engine from £495 (supply only) typically offers better long-term value and reliability.
