By on 19 March 2021 / Leave a comment Updated on: 19th March 2021

A joint venture between Nissan and Renault, the M9R diesel engine has powered many cars and vans since its introduction in 2006. These engines are built in 2.0-litre capacity and produce power ranging from 130hp to 180hp. Commonly seen on UK roads under the bonnet of Renaults, Nissans and the occasional Vauxhall product.

These engines offer low fuel consumption, impressive emissions levels and pack new age technology such as start-stop functions and active thermal management. Reliability is generally good too, with many engines lasting 200,000 miles or more without major repairs. One common issue however, is removal and replacement of faulty diesel injectors.

It is not uncommon for injectors to seize into the engine, making removal almost impossible, even for professionals. This, luckily is a well-known and well documented issue that has led to the creation of many specialist products, such as those featured below, to allow simple and easy injector removal.

Things to Consider Before Purchasing

Vehicle Compatibility

Engine codes can often make choosing the right part for a specific vehicle very difficult. Here is a quick run down of the vehicles that use the M9R engine, that would benefit from use of the featured tools:

  • Nissan Qashqai (2007-2011)
  • Nissan X-Trail (2007-2012)
  • Nissan Primastar (2006-2014)
  • Renault Laguna (2005-2015)
  • Renault Espace (2006-present)
  • Renault Koleos (2007-present)
  • Renault Vel Satis (2007-2010)
  • Renault Trafic (2006-2014)
  • Vauxhall Vivaro (2006-2014)

Check the engine code via the owner’s booklet, under-bonnet panel (which often shows paint codes etc, can sometimes be found in the door aperture) or by contacting your local dealer/ specialist.

Skills & Tools Required

Experience and mechanical skills are highly beneficial for jobs like changing fuel injectors, this is not the simplest of service tasks. Having experience on diesel engines will likely help, though many amateur home mechanics figure it out with the help of online videos and forums.

Basic tools will also be needed to access the injectors, these will vary vehicle to vehicle but specialist equipment is rarely required to remove the correct engine ancillaries.

Brand Reputation

Specialist tools are available nowadays from all manner of different manufactures and sellers. Brands with better reputations and loyal followings have usually built this cache, thanks to high quality offerings and good customer service. Warranties and reputation are important but often, smaller brands and independent toolmakers can create equally useful product for less outlay.

Types of Injector Removal Tool

Removal of seized injectors cannot be done without serious force, here tools are generally split into hand-powered or hydraulically assisted machinery.


Tools that use nothing more than the user’s strength are generally cheaper and simpler than those powered by hydraulics. They may not provide the same pulling force but generally give better accuracy and aren’t as cumbersome to use in cramped engine bays. Less complexity also leads to a lighter tool, as well as reducing the likelihood of failure.


Though more expensive, larger and heavier than hand-powered equipment, hydraulically assisted tools definitely have their place, particularly in professional workshops. The added assistance allows for quicker removal of stuck injectors, while also placing less stress and strain on the user. Extra assistance and ease of removal however does come at the cost of increased purchase price.
