Common issues & diagnosis
The most common issue with BMW’s direct injection fuel injectors is clogging, which can occur due to fuel impurities or the buildup of carbon deposits. Clogged injectors may not deliver the correct amount of fuel, leading to engine misfires, reduced power, poor fuel economy, and uneven engine running.
What is the part's function?
Fuel injectors are responsible for delivering fuel into the engine’s combustion chamber. In direct injection systems, which are common in modern BMW engines, the injector sprays fuel directly into the combustion chamber at high pressure. This allows for more precise control over the amount and timing of fuel delivery, improving combustion efficiency, reducing emissions, and enhancing performance.
How to determine fitment compatibility
Each model will typically have different fuel injectors for each of the engine types that it runs.
The best way to determine compatibility of a part for your vehicle is to match the genuine part numbers. This can be done by decoding your VIN in a BMW parts catalogue.

Interchangeability between models
Fuel injectors are highly-interchangeable. They will often interchange between different engine types that share the same fuel type, regardless of the generation or amount of cylinders.
