Renault Kadjar 1.6 dCi Engine ReplacementCompare Prices & Get Quotes

A Renault Kadjar 1.6 dCi R9M engine replacement typically costs £1,800-£3,200 supply-only for a rebuilt unit, with used engines from £850 and reconditioned from £1,600. Total fitted cost adds 8-12 hours of labour at specialist rates (£55-£75/hr) or dealer rates (£100-£150/hr).

• Rebuilt supply-only: £1,800-£3,200 [ESTIMATED]
• Supply & fit specialist total: £2,300-£4,100
• Main dealer supply & fit: £3,200-£5,000

The most common signs of VGT turbo failure in the R9M engine are loss of power, black smoke from the exhaust, a whistling or whining noise, increased fuel consumption, and in severe cases, the engine management light illuminating with underboost fault codes. If the turbo has failed catastrophically, you may hear a loud grinding noise and the engine may lose all power. Oil consumption and white smoke can also indicate turbo seal failure.

• Loss of power and black smoke are the classic symptoms
• Whistling or whining noise indicates bearing wear or a split intercooler hose
• Catastrophic failure can send debris through the engine

This depends on your Kadjar 1.6 dCi's overall condition and market value. For a well-maintained GT-Line or Premier Edition (worth £8,000-£16,000), a rebuilt engine at £1,800-£3,200 is viable, especially with the 12-month warranty. For a higher-mileage Dynamique Nav example worth under £6,000, a used engine (£850-£1,500) or targeted repairs (turbo, injectors, timing belt) may be more cost-effective.

• Vehicle worth under £6,000: consider used engine or repair
• Vehicle worth £8,000+: rebuilt engine with warranty is sensible
• Factor in overall condition - bodywork, suspension, interior wear

A Renault Kadjar 1.6 dCi engine replacement typically takes 2-3 working days for a specialist workshop, including removal of the old R9M unit, fitting the replacement, and road testing. Main dealers may quote 3-5 days due to scheduling and OEM parts ordering. ECU coding and AdBlue system recalibration are included in supply & fit orders.

• Supply-only delivery: next-day available across the UK
• Supply & fit: book a slot with your nearest specialist
• Express fitting available in some regions

The R9M 414 is the standard 1.6 dCi producing 130bhp with a single variable geometry turbocharger, fitted to Dynamique Nav and Signature Nav trims. The R9M 416 is the high-output twin-turbo variant producing 160bhp, fitted exclusively to GT-Line and Premier Edition trims from 2016-2019. Both share the same 1,598cc displacement and DOHC 16-valve architecture, but the twin-turbo system adds complexity and higher risk of boost control issues.

• R9M 414: 130bhp, single VGT turbo
• R9M 416: 160bhp, twin-turbo system
• Both require the same preventative maintenance - timing belt every 5 years/60k

Used engines are cost-effective (£850-£1,500) but come with unknown service history and no warranty beyond the supplier's standard 30-90 days - risk of the same turbo, injector, or timing belt issues reoccurring. Rebuilt engines (£1,800-£3,200) include new variable geometry turbocharger, injectors, timing belt, water pump, piston rings, bearings, and a 12-month unlimited-mileage warranty, offering peace of mind for long-term ownership.

• Used: best for low-budget repairs on lower-value Kadjars
• Rebuilt: best for long-term ownership (2+ years) and higher-value examples
• Always confirm what components were replaced in a rebuilt unit
