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.

Big Thanks! Had my bmw e46 330ci done yesterday, it has 138k and engine was idling a bit rough,after the carbon clean the rough idling was gone!! its very smooth now, and biggest difference i noticed is in 3rd and 4th engine pulls significantly better, cruising on the motorway at 70-80mph the gauge sits closer to 50mpg. definitely worth it. I`m sure diesel cars should see bigger improvements. 100% recommend !

Had my 2014 3 ltr Toyota hilux and 2011 Audi A4 S line re mapped tonight. Hilux had a tunit tunning box on it before james did his magic, Im always running heavy especially when towing heavy loads on a regular basis, always found the Euro 5 engine under powered for what I do but already notice a huge difference. Torque is very good, pulls nicely all the way through rev range. Wished I'd got it done years ago. Audi A4 was always a disappointment when driving it previously. It's got an automatic box in it and didn't expect to much from it but I was pleasantly surprised when testing. Took it along a series of back roads to find it pulled great all way through rev range. All in all I would highly recommend this professional service offered by james. He has great knowledge in tuning vehicles. He is also very approachable. I was that impressed I'm thinking about getting him to re map a John Deere engine in a forestry machine.

Just had a stage 3 clean done by James on my 407 coupe 2.7 L hdi , I thought it was running fine before the clean and any minor things were just age related, how wrong was I !!! It’s not running like it’s came out the showroom floor yesterday Notice difference in how smooth it runningHow quiet it’s running idling and at speed Can’t recommend UK Carbon Cleaning enough And James who does south Scotland and Newcastle and Carlisle areas TOP BLOKE
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
