What is the main functionality of a lambda probe?

The lambda probe is a sensor that measures the amount of oxygen in the exhaust gases, allowing the engine control unit to regulate the fuel and air ratio.

What is the difference between a lambda probe and an O2 sensor?

Both terms are used interchangeably – the O2 sensor is the English name for the lambda sensor. In practice, they refer to the same exhaust system component.

What are the symptoms of a damaged lambda probe?

The most common symptoms include a loss of power, increased fuel consumption, unstable RPMs and the "check engine" light coming on.

Is the lambda probe compatible between different car models?

Not always – compatibility depends on the manufacturer, year, and engine type. It's best to select a part by its VIN.

How often should a lambda probe be replaced?

On average, every 100,000–150,000 km, although this depends on driving style and fuel quality.

Do O2 sensors affect fuel consumption?

Yes, a damaged sensor can increase fuel consumption by up to 15–20% because the engine control unit does not receive correct data.

Where can I find lambda sensors for my car?

The Global Parts store offers lambda sensors and O2 sensors for most popular brands – BMW, Audi, Mercedes, Volkswagen, Mini and others.

Original lambda sensors and O2 sensors – precise exhaust emission control

A wide selection of probes and sensors for BMW, Audi, Mercedes, MINI, Volkswagen and others

Lambda sensors and O2 sensors are essential exhaust system components that monitor oxygen levels, supporting efficient fuel combustion and reducing harmful emissions. Their proper operation is essential for meeting emission standards and ensuring optimal engine performance. At ** Global Parts, ** you'll find a wide selection of used car parts , including lambda sensors and O2 sensors, ideal for BMW , Audi , Mercedes , Volkswagen , Mini , and more .

What are the functions of lambda probes and O2 sensors ?

Lambda sensors and O2 sensors perform key functions in a vehicle's exhaust system: Measuring the oxygen level in the exhaust gases – Lambda sensors analyze the oxygen content in the exhaust gases, providing data to the engine control unit. Air-fuel mixture adjustment – Based on the probe measurements, the engine control unit adjusts the fuel and air ratio, ensuring optimal combustion. Reduction of exhaust emissions – Lambda sensors support the operation of the catalytic converter, helping to reduce harmful emissions. Monitoring the operation of the catalytic converter – Lambda sensors located behind the catalytic converter monitor its efficiency, informing about any faults. In practice, lambda sensors are divided into narrowband (voltage varies between 0.1 and 0.9 V) and broadband (providing detailed data over a wider measurement range). Broadband O2 sensors are used in newer Audi and BMW models, among others, because they enable more precise fuel control. These differences are important when matching parts – using the wrong sensor can result in engine errors.

Why is it worth taking care of lambda probes and O2 sensors ?

Damage or wear to lambda and O2 sensors can lead to engine performance and emissions issues. Typical symptoms include: Loss of power and uneven engine operation – A damaged lambda sensor can cause incorrect adjustment of the fuel-air mixture. Increased fuel consumption – A malfunctioning lambda sensor can lead to a richer fuel mixture, increasing fuel consumption. Higher exhaust emissions – Faulty lambda sensors can disrupt the operation of the catalytic converter, causing increased emissions of harmful substances. Dashboard Errors – Problems with lambda sensors are often indicated by the check engine light. The typical lifespan of lambda sensors is 80,000 to 160,000 km, depending on the manufacturer and operating conditions. O2 sensors are exposed to high temperatures (up to 900°C) and contact with residual fuel, so replacing them at the right time is important for both environmental protection and fuel economy . Correctly matching the sensor by VIN or model specification ensures compatibility with the vehicle's exhaust system. At Global Parts, we offer original used lambda sensors and O2 sensors that have undergone extensive quality testing, ensuring their durability and reliability.

How to choose the right lambda probes and O2 sensors ?

When selecting lambda sensors and O2 sensors, there are several key aspects to consider: Vehicle-specific fit – Every exhaust system has its own specific technical requirements. At Global Parts, you'll find lambda sensors and O2 sensors perfectly matched to BMW , Audi , Mercedes , Volkswagen , Mini , and more . Lambda Sensor Type – Make sure the sensor you choose matches your system (single, two, three or four wire). Technical condition – Used lambda probes and sensors should be free from mechanical and electrical damage, and their cables should be in good condition. For easier comparison, the basic types of lambda sensors and their characteristics are listed below.

Probe type	Number of wires	Application	Voltage range
Single-wire	1	Older car models (e.g. Opel Kadett, VW Golf II)	0.1–0.9 V
Four-wire	4	Standard in cars since the 1990s (BMW, Mercedes, Audi)	0.1–0.9 V
Broadband	5–6	Modern petrol and diesel engines (Audi A4 B8, BMW E90)	Wider range of data

Why choose used lambda sensors and O2 sensors ?

Used car parts , such as lambda sensors and O2 sensors, are a practical solution that allows you to save money while maintaining high quality. By choosing used lambda sensors and O2 sensors, you gain: Lower costs – Used components are much cheaper than new ones, but offer equally high quality. Ecology – Recycling car parts supports environmental protection and reduces waste. A wide range – In our store you will find lambda sensors and O2 sensors for the most popular car brands. It's worth noting that many of the O2 sensors offered by Global Parts come from premium car brands, where original parts are known for their high durability. This ensures a perfect fit for their model and full compliance with factory parameters. This makes purchasing these components a cost-effective and technically sound solution.

How to take care of lambda probes and O2 sensors ?

To ensure that lambda probes and O2 sensors function reliably for a long time, it is worth following a few rules: Regularly check the condition of the lambda sensors during exhaust system diagnostics, especially if the check engine light comes on. Use high-quality fuel to reduce deposits and contaminants in the exhaust system. Replace lambda sensors according to the manufacturer's recommendations or if there are visible signs of malfunction. If you need a replacement, you'll find the right used car parts at Global Parts that will restore full functionality of your exhaust system.
