Variant HistoryRenault Laguna 2.0 dCi - Engine History & Specs at a Glance
The 2.0 dCi was introduced to the Renault Laguna II range in 2005 as a more powerful diesel alternative to the 1.9 dCi, using the Nissan-developed M9R engine family. It continued into the Laguna III (2007-2015) with various power outputs from 150 hp to 180 hp, becoming the flagship diesel engine for the range. The M9R engine uses a timing chain rather than a belt - a significant reliability improvement over earlier Renault diesel engines.

Common Failure
Turbo actuator failure is a known issue on early M9R engines - the wastegate actuator arm can seize, causing loss of boost and power. EGR valve clogging from soot buildup is also common.
The Renault Laguna 2.0 dCi (M9R engine family) is generally more reliable than the 1.9 dCi, with a timing chain rather than a belt. However, it has specific, well-documented issues - particularly around the EGR system, turbo actuator and DPF. Rebuilt engines through EnginesMarket include upgraded components addressing the original failure point, plus a minimum 12-month unlimited-mileage warranty.
The Most Common Renault Laguna 2.0 dCi Problem
Affected Vehicles
Renault Laguna 2.0 dCi (all M9R variants)
Typical Failure Mileage
80,000-120,000 miles
Root Cause
The wastegate actuator arm can seize, preventing the turbo from generating boost. The arm for the wastegate actuator doesn't move when started or when revving, and the arm can become stuck solid. Loss of power and increased fuel consumption are common symptoms. The boost pressure regulator solenoid valve may also malfunction.

Vehicle Value Check
Vehicle Value Check
A typical 2005-2015 Laguna 2.0 dCi is worth £1,500-£6,000 depending on mileage and condition. For a sub-£2,500 example, a £350-£650 actuator replacement is a sensible repair. If the turbo has failed, a rebuilt engine with warranty (£1,800-£3,500) may be the most cost-effective option.
Our Recommendation
Our Recommendation
Turbo actuator failure is a known issue on M9R engines. If you're experiencing loss of power or increased fuel consumption, have the turbo system inspected immediately. Actuator replacement at £350-£650 specialist cost is significantly cheaper than a full turbo replacement. Check all vacuum pipes for leaks first - these are often the cause of actuator problems.
Don't Let Turbo or DPF Failure Write Off Your Renault Laguna 2.0 dCi
Whether you're dealing with turbo actuator failure, EGR clogging, DPF issues or timing chain wear on your Laguna 2.0 dCi, a rebuilt engine with upgraded components and a 12-month warranty is often the most cost-effective long-term solution.

Renault Laguna 2.0 dCi Engine ReplacementFrequently Asked Questions
Question 1How much does a Renault Laguna 2.0 dCi engine replacement cost in the UK-
A Renault Laguna 2.0 dCi engine replacement typically costs £1,800-£3,500 for a rebuilt unit supply-only, with fitted prices ranging from £2,500-£4,500 depending on the engine code (M9R 760 vs M9R 820) and labour rates.
- Used engines: £600-£1,500
- Reconditioned: £1,300-£2,800
- Rebuilt with warranty: £1,800-£3,500
- Fitting labour: 8-12 hours at £65-£100/hr
Question 2What are the signs of turbo actuator failure on a Renault Laguna 2.0 dCi-
The most common signs are loss of power and increased fuel consumption. The wastegate actuator arm can seize, preventing the turbo from generating boost.
- Loss of power when accelerating
- Increased fuel consumption
- Engine management light
- Turbo not boosting - actuator arm stuck
Question 3Does the Renault Laguna 2.0 dCi have a timing belt or chain-
The 2.0 dCi (M9R engine) uses a timing chain, not a belt. This is a significant reliability improvement over the 1.9 dCi which uses a belt. The chain should be inspected from approximately 200,000 km (124,000 miles).
- Timing chain - not a belt
- Inspect from 200,000 km
- Chain can stretch over time
Question 4Is the Renault Laguna 2.0 dCi engine reliable-
The 2.0 dCi (M9R) is generally more reliable than the 1.9 dCi, with the timing chain being a significant improvement. However, it has known issues with the EGR valve, DPF and turbo actuator. With regular maintenance, the engine can last 150,000+ miles.
- More reliable than 1.9 dCi
- Timing chain is a major improvement
- EGR/DPF issues are common
- Regular maintenance is essential
Question 5What's the difference between the 2.0 dCi engine codes-
The Laguna 2.0 dCi was offered with several M9R engine codes: M9R 760 (173 hp, Laguna II, 2005-2007), M9R 700 (150 hp, Laguna III), M9R 815 (175 hp, automatic, 2008-2015) and M9R 820 (180 hp, GT line, 2008-2015).
- M9R 760: 173 hp, Laguna II
- M9R 700: 150 hp, Laguna III
- M9R 815: 175 hp, Laguna III auto
- M9R 820: 180 hp, Laguna III GT
Question 6Is it worth replacing the engine in a Renault Laguna 2.0 dCi-
It depends on the vehicle's value and what has failed. For a 2005-2015 Laguna 2.0 dCi worth £1,500-£6,000, a £1,800-£3,500 rebuilt engine is usually worthwhile if the car is otherwise sound. Turbo actuator or EGR failure often makes repair more cost-effective than full replacement.
- Cars worth £2,500+: rebuilt engine with warranty is recommended
- Cars worth £1,500-£2,500: evaluate both options carefully
- Turbo actuator failure: repair is usually cheaper than replacement
- Cars worth under £1,500: consider used engine or scrap
