Renault Kadjar 1.5 dCi Engine Replacement Compare Prices & Get Quotes

A replacement engine for a Renault Kadjar 1.5 dCi typically costs £1,450-£2,250 for a reconditioned supply-only unit. Used engines start from £650. Fitting adds 8-12 hours of labour at £65-£90/hr, bringing the total fitted cost to £2,000-£3,500 at an independent specialist. Dealer pricing is significantly higher.

• Used engine supply: £650-£1,300
• Reconditioned supply: £1,450-£2,250
• Rebuilt supply: £2,000-£2,800

The most common signs are loss of power, rough idle, poor fuel economy, and the engine management light illuminating. On diesel Kadjars, EGR valve clogging causes hesitation and smoke, while DPF blockage triggers warning lights and limp mode.

• Loss of power and rough idle indicate EGR issues
• DPF warning light and limp mode indicate filter blockage
• Regular motorway driving helps prevent DPF problems

The 1.5 dCi is generally regarded as a dependable engine, but it has several well-documented weak points. EGR valve clogging, DPF issues and injector wear are common on higher-mileage examples. Regular maintenance - particularly timing belt replacement every 60,000 miles or 5 years - is the key to longevity.

• EGR and DPF issues are the most common problems
• Timing belt replacement is critical every 60,000 miles or 5 years
• Regular oil changes and motorway driving help prevent issues

It depends on the vehicle's value. Early Kadjar examples (2015-2017) are worth £4,000-£10,000 - a full engine replacement at £2,000-£3,500 may represent 20-70% of the car's value. Later examples with higher values (£8,000-£18,000) generally justify replacement if the rest of the car is in good condition.

• Evaluate the total repair cost vs. the vehicle's current market value
• Consider part-exchange or selling for spares if repair costs exceed 60% of value
• Always get multiple quotes before committing

The K9K 730 and K9K 732 both produce 110hp and share the same 1.5-litre (1,461cc) displacement. The K9K 730 was fitted to early Kadjar models (2015-2017) while the K9K 732 was fitted from 2015-2018. Both engines share the same architecture and failure points.

• K9K 730: Early 1.5 dCi, Kadjar (2015-2017)
• K9K 732: 1.5 dCi, Kadjar (2015-2018)
• Both engines share the same architecture and failure points

The 1.5 dCi (K9K) uses a timing belt, not a chain. The belt requires replacement at the manufacturer-recommended interval - typically every 60,000 miles or 5 years, whichever comes first. Neglecting the timing belt can lead to catastrophic engine failure if it breaks.

• Timing belt, not chain - scheduled replacement required
• Replacement interval: 60,000 miles or 5 years
• Belts on pre-2018 models may have different durability characteristics
