Repair options & estimated costs (UK ranges)
| Repair tier | Dealer price | Specialist price | What it involves | Longevity / suitability |
|---|---|---|---|---|
| Minor - EGR Cooler Replacement | £1,200 - £1,800 | £750 - £1,200 | Replace cooler, clean EGR valve, reset adaptations | 20k-40k miles if driving pattern unchanged |
| Intermediate - EGR System Overhaul | £1,800 - £2,600 | £1,100 - £1,700 | Cooler + valve + pipework + DPF check | 40k-60k miles with improved components |
| Full Replacement - Rebuilt 4N14 Engine | £3,800 - £5,200 | £2,200 - £3,400 | Supply & fit rebuilt engine with upgraded EGR components | 80k+ miles with warranty coverage |
Our recommendation
On a Mitsubishi Outlander worth £4,000-£8,000, a rebuilt 4N14 with upgraded EGR components offers better long-term value than repeated cooler replacements. We recommend replacement if the engine has exceeded 80k miles or shows additional wear signs.
