Want to avoid replacing your O2 Sensor?
Carbon Cleaning is your best option!
What is the purpose of the O2 / Lambda sensor?
The O2 (Oxygen) Sensor or Lambda Sensor as it is known in the the trade is located before the Catalytic Converter in the exhaust system.
The job of this probe is to measure the amount of oxygen left in the remaining burnt gases as they exit the engine and send this information to the ECU (Engine Management Unit). The ECU can then calculate the correct fuel / air mixture for the ideal combustion which lowers fuel consumption and in turn reduces emissions. This is important for passing MOT and roadside emissions tests.
More recent regulations require a second 02 sensor to be positioned after the Catalytic Converter so that the effectiveness of the converter can be measured.
Why you should the Lambda / 02 Sensor be replaced?
If there the sensor is faulty it will send incorrect readings to the ECU and therefore the calculated air to fuel ratios will be incorrect. This will cause the engine to stutter, run lumpy and increase fuel consumption.

I’ve used Yasir many times for stage3 Carbon Clean over the past few years. Yasir demonstrates in-depth knowledge & experience in gaining high end results for each outcall as I have recommended him to family & friends who have all been very pleased with the service. It’s a safe & risk free process used to reduce emissions & overall performance of a vehicle. I’ve personally noticed the difference a carbon clean makes to the performance of a car soon as it’s been completed.

What an absolutely amazing gentleman this guy is. goes above and beyond the call of duty. he even had a look over a friend's car who was here while I was having my state 2 carbon clean done, which I might add has made a huge difference. he even found a leaking turbo pipe I didn't know I had. well worth every penny. thx again. see u soon for the ST remap 🙂

Had James out to my 2008 X5 3.0d sport great service at great price. Good peace of mind getting the engine turbo egr and dpf cleaned car does run noticeably smoother. So impressed with the work he did on my car and my son in laws im having him back in couple of weeks for the remapping service.
When should the Lambda / 02 Sensor be replaced?
As long as it’s not shortened by other engine malfunctions the average lifespan of an 02 sensor is 80,000 to 90,0000 miles.
Exhaust leaks can damage the sensor probe which can lead to dangerously high temperatures. The probe canse also become contaminated by unburned fuel, if this occurs it is irreversible.
Following a strict servicing routine, including the usual oil changes, spark plugs, air filters etc, is required to ensure maximum life of the sensor.
Signs that your Lambda / O2 Sensor needs to be replaced:
- The engine starts to stutter or suddenly suffers from reduced performance
- The check engine management light illuminates
The easiest way to diagnosis a faulty Lambda / 02 sensor is with an OBD (On-Board Diagnostic computer). Unless you have access to an OBD reader and are competent in using one this should be completed by a professional.
Typically garages charge up to £70 for such a diagnostic, alternatively we include a FREE diagnostic with all of our Carbon Cleaning Services starting from just £89.99
Cleaning your Lambda Sensor / O2 Sensor?
There are numerous ways to clean or replace the Lambda Sensor / 02 Sensor with varying prices.
The costliest option is a complete replacement part. Most mechanics will recommend this – Why? It’s generally their only solution. The price of a Lambda / O2 sensor varies on average between £180 and £300. NOTE: Newer vehicles have two sensors and it’s not uncommon that if one has been damaged the other will have been as well
