Nissan NV300 Engine ReplacementCompare Prices & Save

Nissan NV300 R9M engine replacement typically costs £1,800-£3,400 for a rebuilt unit supply-only, depending on engine code (dCi 120 vs dCi 140), GVW variant, and whether supply & fit is included. Commercial van operators should budget for potential downtime.

• Rebuilt R9M 408 (dCi 120) averages £1,800-£2,900 supply-only
• High-output R9M 412 (dCi 140) ranges £2,100-£3,400 supply-only
• Supply & fit adds £450-£850 depending on location and van variant
• All rebuilt engines include 12-month unlimited mileage warranty

All Nissan NV300 models use Renault-sourced R9M 1.6L dCi engines: R9M 404 (90hp), R9M 408 (120hp), R9M 409 (125hp), R9M 412 (140hp), or R9M 414 (145hp). Enter your registration to confirm exact compatibility.

• R9M 408 and R9M 412 are most common across panel and combi variants
• Euro 6d models (2021+) use revised R9M 409/412/414 with AdBlue
• Engine code is stamped on block; DVLA lookup confirms exact fitment
• Cross-compatibility exists between NV300, Trafic III, Talento, Vivaro

NV300 R9M engine replacement typically takes 8-12 hours labour plus sourcing time; most commercial van jobs complete within 2-3 days including delivery, minimising business downtime for tradespeople and fleet operators.

• Engine sourcing: 1-2 days for common R9M 408/412 codes
• Fitting labour: 8-12 hours at commercial van specialist garage
• Total turnaround: 2-3 days typical for supply & fit service
• Next-day fitting available for urgent commercial van replacements

Yes, all rebuilt and reconditioned Nissan NV300 R9M engines supplied through EngineMarket include a minimum 12-month unlimited mileage warranty as standard, with commercial van duty cycle coverage explicitly confirmed.

• 12-month unlimited mileage warranty standard on rebuilt units
• Commercial van duty cycle explicitly covered in warranty terms
• Warranty valid UK-wide with network of approved fitting centres
• Used engines may have shorter warranty; confirm terms before purchase

Rebuilt R9M engines receive full disassembly and upgraded components; reconditioned units are cleaned and tested with replaced wear items; used engines are low-mileage donor units with verified history but no rebuild.

• Rebuilt: Full strip, machining, new components, upgraded for known failures
• Reconditioned: Cleaned, tested, wear items replaced, cost-effective option
• Used: Low-mileage donor unit, compression-tested, budget solution
• All rebuilt/reconditioned include 12-month warranty; used varies by supplier

Declaring a replacement R9M engine to your insurer is required, but typically doesn't change premiums if the replacement matches original specifications; commercial van policies may require documentation of the rebuild.

• Insurers require notification of engine replacement for commercial policies
• Like-for-like R9M replacement usually has no premium impact
• Keep warranty certificate and engine number documentation for claims
• Upgraded components (EGR, turbo) may require specialist insurer confirmation

If repair quotes exceed £1,500, your NV300 has multiple warning lights, or downtime exceeds 3 days, a rebuilt R9M engine often offers better long-term value for commercial van operators minimising business disruption.

• Multiple failures (EGR + turbo + DPF) favour full replacement
• Repair costs over £1,500 rarely justify vs rebuilt engine value
• Commercial downtime costs often exceed engine price difference
• Free diagnostic check available before committing to replacement

Upgrading from dCi 120 to dCi 140 R9M requires ECU reprogramming, potential gearbox compatibility checks, and insurer notification; most commercial operators prefer like-for-like replacement to avoid complications.

• R9M 408 to 412 swap needs ECU coding and potential turbo calibration
• Gearbox and drivetrain compatibility must be verified before upgrade
• Insurer notification required for power output changes on commercial policies
• Like-for-like replacement avoids complexity and maintains warranty validity

You'll need your NV300 V5C registration document, engine number from the replacement unit, and warranty certificate; suppliers provide documentation for DVLA engine number updates on commercial vehicles.

• V5C registration document required for engine number update
• Replacement engine number provided on warranty certificate
• DVLA notification required for engine number change on commercial vans
• Keep all documentation for MOT, insurance and resale purposes

R9M EGR cooler clogging from short-journey commercial use is the most frequent NV300 failure, followed by turbo VNT actuator wear and DPF regeneration issues on urban stop-start duty cycles.

• EGR cooler failure most common at 60k-100k miles on urban routes
• Turbo VNT actuator wear causes boost loss on dCi 140/145 variants
• DPF soot overload from frequent short journeys damages exhaust system
• Timing chain tensioner wear reported on higher-mileage first-gen units
