Renault Dokker Engine ReplacementReconditioned & Used Prices Compared

Typical rebuilt Renault Dokker engine prices range from £1,200 for a basic K9K diesel to £4,200 for a 1.2 TCe turbo petrol, supply only. Supply & fit adds £400-£900 depending on garage location and engine complexity.

• K9K 1.5 dCi diesel rebuilt: £1,200-£3,800 supply only
• H4M 1.6 SCe petrol rebuilt: £1,400-£3,200 supply only
• H5Ft 1.2 TCe turbo petrol rebuilt: £1,600-£4,200 supply only
• Supply & fit service typically adds £400-£900 to engine price
• Prices vary by engine code, mileage verification and supplier location

The 1.2 TCe turbo petrol's timing chain stretch is the most documented failure, risking catastrophic damage from 60k miles. On diesel 1.5 dCi units, injector wear and DPF clogging drive most replacement enquiries.

• H5Ft 1.2 TCe: timing chain stretch from 60k miles, oil consumption issues
• K9K 1.5 dCi: injector wear from 90k miles, EGR/DPF faults on high mileage
• H4M 1.6 SCe: oil seal leaks after 70k miles, generally reliable otherwise
• Always verify engine code before ordering replacement parts or engines
• Preventative maintenance can avoid costly failures on all engine types

Yes, when sourced from vetted UK specialists. Reconditioned Renault Dokker engines undergo inspection, cleaning and replacement of worn seals/gaskets, typically with a 12-month unlimited mileage warranty for peace of mind.

• Reconditioned engines replace seals, gaskets and wear items after thorough inspection
• 12-month unlimited mileage warranty standard on EngineMarket network units
• Ideal for K9K diesel and H4M petrol engines with good block condition
• Always verify supplier credentials and warranty terms before committing
• Rebuilt option available for maximum longevity with upgraded internal components

Your Renault Dokker engine code is stamped on the engine block (visible near the gearbox) and listed on the VIN plate under the bonnet or in your V5C logbook under section D.2.

• Check engine block stamp near gearbox for code like K9K 636 or H4M 737
• VIN plate under bonnet or V5C logbook section D.2 shows engine code
• Enter registration on EngineMarket for instant DVLA-verified engine identification
• Common codes: K9K (diesel), H4M/K7M (1.6L petrol), H5Ft (1.2 TCe)
• Correct code ensures compatibility and avoids costly ordering mistakes

Technically possible but not recommended. Swapping petrol to diesel in a Renault Dokker requires ECU reprogramming, wiring harness changes, emissions system modifications and may fail MOT or invalidate insurance.

• Engine swap requires ECU coding, wiring changes and emissions system adaptation
• May fail MOT emissions test or invalidate vehicle insurance coverage
• Legal paperwork and DVLA notification required for fuel type changes
• Rebuilt 1.2 TCe with timing chain upgrades is safer, legal and warranty-backed
• Always consult a specialist before attempting cross-fuel engine swaps

Yes. Every rebuilt or reconditioned Renault Dokker engine supplied through EngineMarket includes a minimum 12-month unlimited mileage warranty. Terms vary by supplier; always confirm exact coverage before ordering.

• Minimum 12-month unlimited mileage warranty standard on network engines
• Warranty covers internal components; ancillaries may have separate terms
• Keep service records and use correct oil specs to maintain warranty validity
• Supply & fit installations often include labour warranty from fitting garage
• Always get warranty terms in writing before confirming your order

Typical turnaround is 2-4 days from order to collection: 24-48 hours for engine dispatch plus 1 day for professional fitting, testing and handover at your local garage.

• Engine dispatch: 24-48 hours from order confirmation for in-stock units
• Professional fitting: typically 1 working day at vetted UK garage
• Total turnaround: 2-4 days depending on engine availability and garage schedule
• Mobile fitting available in some areas for added convenience
• Commercial Van users can request priority scheduling to minimise downtime

Used engines offer the lowest upfront cost but carry variable condition risk. For budget repairs on older Authentique models they can be sensible; for Expression/Stepway/Van, reconditioned units with warranty offer better long-term value.

• Used engines: £800-£2,400 but condition and mileage vary significantly
• Always request compression test results and service history before purchase
• Typical warranty only 3-6 months vs 12 months on reconditioned units
• Reconditioned option adds £400-£800 but includes new seals and warranty
• Best for low-budget repairs on pre-2016 Authentique with simple K7M engines

Compliance depends on the original vehicle's emissions standard, not the replacement engine. A Euro 6 K9K 872 Blue dCi replacement maintains ULEZ compliance; older Euro 5 units do not, regardless of engine condition.

• ULEZ compliance is based on vehicle's original Euro rating, not replacement engine
• Euro 6 K9K 872 Blue dCi engines maintain compliance for eligible vehicles
• Euro 5 K9K 636/646 replacements do not make non-compliant vehicles ULEZ-exempt
• Petrol replacements (H4M/H5Ft) are generally ULEZ-compliant if vehicle was originally petrol
• Check your vehicle's Euro rating on the TfL website before ordering

Reconditioned engines receive cleaning, inspection and replacement of seals/gaskets. Rebuilt engines undergo full machining, new internal components and upgrades targeting known failures like timing chains, offering maximum longevity.

• Reconditioned: inspection, cleaning, new seals/gaskets; ideal for good-condition blocks
• Rebuilt: full machining, new pistons/rings, upgraded components for known failure points
• Rebuilt recommended for H5Ft 1.2 TCe needing timing chain and piston ring upgrades
• Both include 12-month warranty; rebuilt typically £200-£600 more than reconditioned
• Choose rebuilt for high-mileage vehicles or maximum long-term reliability
