The Best M47 & M57 Injector Removal Tool

BMW’s diesel engines have consistently set the benchmark in the industry. Long known for their power, reliability and frugality, the brand always seems to set a high-water mark for all matters under the bonnet. This legacy continued with the introduction of the M57 & M47 engines in 1998. In their 15-year life span the engines saw use throughout BMW’s model range along with being sold to other competitor brands.

Though known for being dependable engines, a major flaw shared between them, come service time, is seized fuel injectors. Not uncommon to many diesel vehicles in fact, the heat and stresses on the injectors over time can cause them to seize in place, making removal almost impossible using regular tools. Many have damaged engine cylinder heads and ancillaries with large hammers and pry bars trying to remove M57 and M47 engine diesel injectors.

Thankfully tool manufacturers spotted the need for specialist tooling, allowing for easy and safe removal of seized diesel injectors. No damage will be caused to the expensive cylinder head or delicate engine components that surround it.

Things to Consider Before Purchasing

Vehicle Compatibility

Engine codes can easily cause confusion, though most vehicles will show the correct code via a plate found in the engine bay or drivers/ passenger door aperture. To make it easy here is a list of the most common vehicles fitted with the BMW M57 diesel engine:

• BMW 3-series 330d (1999-2008), 335d (2006-2013) & 325d (2006-2009)
• BMW 5-series 525d (2000-2010), 530d (1998-2010) & 535d (2004-2010)
• BMW 6-series 635d (2007-2010)
• BMW 7-series 730d (1998-2008)
• BMW X3 3.0d/3.0sd (2003-2010)
• BMW X5 3.0d/3.0sd/xDrive35d (2001-2010)
• BMW X6 xDrive35d (2008-2010)
• Range Rover 3.0l Td6 (2002-2005)

And those that use the M47 engine:

• BMW 1-series 118d/120d (2004-2007)
• BMW 3-series 318d (2001-2007) & 320d (1998-2007)
• BMW 5-series 520d (2000-2007)
• BMW X3 2.0d (2005-2007)
• Rover 75 CDT/CDTi (1999-2005)
• Land Rover Freelander Td4 (2001-2006)
• MG ZT CDT/CDTi (2001-2005)

Other models may be included, we recommend checking your owner’s manual or contacting a local dealership/ specialist if unsure.

Skills & Tools Required

Replacing fuel injectors is a time-consuming task and one that requires some level of skill and experience. Access to these parts will require some basic disassembly of engine ancillaries. Those with some mechanical experience should have no trouble but, for complete amateurs we recommend getting assistance from someone better qualified or with some level of automotive mechanical experience.

Outside of the kits mentioned below, it is vital to have access to a basic set of sockets, screwdrivers and spanners to allow access to the fuel injectors.

Brand Reputation

Many tools can sell on brand reputation alone, thanks mostly to high quality products, good customer service and long warranties. While more expensive brands may offer confidence in tool quality and longevity (particularly important for professional mechanics), those working on their driveway may find the same practical use in a cheaper “off-brand” tool. They may not hold the same quality but, will likely be good enough for at least a few uses and save some money off initial purchase price.
