Repair options & estimated costs (UK ranges)
| Repair tier | Dealer price | Specialist price | What it involves | Longevity / suitability |
|---|---|---|---|---|
| Minor - EGR Blank/Replace | £800 - £1,400 | £450 - £850 | EGR valve cleaning or replacement, cooler bypass | Temporary fix; may not prevent recurrence on high-mileage units |
| Full Replacement - Rebuilt Engine | £4,200 - £6,800 | £1,620 - £3,200 | Supply & fit rebuilt 4N13/4N14 with upgraded EGR components, bench tested, 12-month warranty | Long-term solution; addresses root cause with upgraded internals |
Our recommendation
On an ASX worth £4,000-£8,000, a rebuilt engine often represents better value than repeated EGR repairs. If caught early, an EGR blank may extend life, but once coolant contamination occurs, replacement is usually the economical choice.
