Owning a BMW comes with the responsibility of ensuring its high-performance standards are maintained. One of the common issues BMW owners face is oxygen (O2) and nitrogen oxide (NOx) sensor clogging and errors, which can lead to poor fuel efficiency, increased emissions, and expensive repairs.
In this guide, we’ll show you how to address this issue effectively using Liqui Moly products and best practices for maintaining your vehicle's health.
What Causes Oxygen/NOx Sensor Issues in BMWs?
· Carbon and soot buildup in the exhaust system,
· Poor fuel quality,
· Inefficient combustion,
· Skipping regular oil changes,
· Faulty catalytic converters,
These problems not only damage sensors but also impact the catalytic system and engine performance.
Step 1: Cleaning the Catalytic and Exhaust System
To resolve clogging and restore the efficiency of your oxygen/NOx sensors, start by cleaning the exhaust system using these Liqui Moly products:
Breaks down carbon deposits in the catalytic converter and exhaust pipes.
Restores exhaust flow and sensor accuracy.
(Tip: Use this cleaner every 5,000 km to maintain optimal performance.)
Cleans the fuel injectors for efficient combustion restoring performance and durability.
Prevents unburned fuel from clogging sensors.
Improves fuel quality while raising the octane levels for cleaner combustion.
Reduces buildup that can harm your sensors.
(Tip: Use Octane Plus whenever you refuel with lower-grade Petrol.)
Step 2: Best Practices for a Quality Oil Change
A proper oil change is crucial for sensor longevity and engine performance. Here’s how to ensure the best results:
1. Perform an Engine Flush
Use Liqui Moly Engine Flush to remove sludge and old deposits from inside the engine before adding new oil.
Promotes cleaner combustion and reduces contaminants in the exhaust.
2. Choose High-Quality Engine Oil
Select a Liqui Moly oil grade that matches your BMW’s specifications.
High-quality oil reduces carbon buildup, protecting sensors and the catalytic converter.
Always use genuine or high-quality oil filters, spark plugs, and air filters during an oil change.
Clogged filters can introduce impurities, reducing engine and sensor performance.
How These Practices Help Your BMW's Oxygen/NOx Sensors
By incorporating the above steps into your BMW’s maintenance routine, you can:
Extend the life of your oxygen and NOx sensors.
Improve engine efficiency and fuel economy.
Reduce harmful emissions.
