Detailed Description

Standard Ignition LSF133 is a replacement fuel level sensor used to monitor fuel tank level and send the signal to the vehicle’s gauge or control module. This part is specified for the left side on 2006-2018 BMW X5 and 2008-2019 BMW X6 applications. If your BMW X5 or BMW X6 shows inaccurate fuel readings, intermittent gauge movement, or a fuel level warning that does not match the amount of fuel in the tank, this sensor is the type of component commonly inspected and replaced.

The LSF133 uses a plug-style connector with one male connector and two female blade terminals, making it important to match the connector style and position before ordering. Standard Ignition LSF133 is a practical replacement for BMW fuel level sensor service where the left-side sender is required.

What It Is Used For

• Restoring fuel gauge accuracy on BMW X5 and BMW X6 models
• Addressing erratic or fluctuating fuel level readings
• Replacing a worn or failed left-side tank sender
• Correcting fuel level warning behavior caused by sensor signal issues
• Resolving sender-related diagnostic concerns in the fuel tank system

Installation Notes and Tips

Verify the vehicle year, model, and left-side location before installation. Match the connector shape, terminal style, and electrical interface to the original sensor. On BMW X5 and BMW X6 applications, confirm the sender position in the tank assembly so the replacement matches the original layout. Standard Ignition LSF133 should be installed with care to avoid damage to the connector or fuel tank components.

Quality Assurance

Standard Ignition supplies replacement electrical and fuel system components for service applications, and LSF133 is built to meet the fitment and connector requirements listed for the specified BMW X5 and BMW X6 models.
