Fuel Injection

Fuel Injection Service in Belmont, MA - Boston Motor Werks

Boston Motor Werks is proud to provide Fuel System Maintenance services to BMWs, Audis, Mercedes, and Porsche vehicles in the Belmont, and greater Boston area.



The evolution of modern BMWs, as well as the environmental concerns for emissions, has seen more precise and calculated fuel mixtures. Fuel systems thus there have become more complicated and increasingly sensitive, especially considering the poor quality of many of our fuels, both high in sulfur and ethanol. Direct fuel injection systems have been stressed the most from the combination of these factors, but we are seeing more and more standard non-direct systems experience fuel pump and fuel injector failure due to poor fuel quality. Carbon builds up is one of the combustion engine’s worst enemies, causing poor running characteristics, decreased performance, and increased fuel consumption. While there are many fuel system treatments available to put in your fuel tank, often the cleaning of the fuel injectors is very limited by the time the diluted cleaner makes it to the fuel rail. BMW offers a fuel injection system that plugs directly in the fuel rail and cleans the fuel injectors right away. This is the most efficient and direct way to clean the injectors without removal. Very noticeable differences are made, especially on higher mileage automobiles. This service provides increased power and performance with improved fuel efficiency and is available on almost any recent model.


BMW Fuel Injection Cleaning and Inspection


Bring your car in for a thorough and detailed inspection and cleaning of your fuel injectors. We offer this service on any BMW model to help improve performance, efficiency, and longevity of the entire fuel system. Basic inspections include: flow testing of the injectors to make sure they are spraying at factory spec (fuel pressure within .5 – 3 psi), visual inspection to check for leaks or damage, missing components such as seals and gaskets, bad vacuum lines/tubes, timing chain rattle (if applicable), overall cleanliness of the engine bay (dirt build up), etcetera. We want our customers to be informed and educated about their car’s maintenance, so when you bring your car in for a service we will also sit down and go over the results with you and detail what is recommended (if anything), and why. Every mileage interval or vehicle condition may vary. We carefully examine each individual vehicle to determine if any additional services are needed, or if all required maintenance has been completed.
