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.

Recently had one car remapped and another a carbon clean. Really good service very happy with both. Kept updated by email regarding time of appointment. On the day James turned up on time and went through the whole process, if anything I was probably asking too many questions, however he took the time to answer all my queries. There had been a fault displayed on the dash which 2 garages insisted was a particulate filter issue which would have cost me hundreds of pounds, however after a quick check James found the issue was only a sensor issue which has been replaced at a greatly reduced cost. highly recommend.Marc Hone
Large Diesel but lots of small journeys since using the train a lot, so knew the carbon would be an issue (as cost me £900+ to get it sorted a few years back in similar case).Anyhow, noticed it was low on power in low revs and running with a K&N air filter so replaced (not recharged) and improved slightly, then cleaned out EGR valve of lots of carbon, issue still there.Carbon cleaned my car and the other halfs (worth the cash as a prevention and with a generous 2nd car discount to be honest) and the improvement is brilliant. Smoother revving and power delivery, better mpg and quieter tickover undoubtedly. Unfortunately didn't resolve my issue as I later found it was my MAF sensor which I later cleaned and now runs lovely. Still glad I tried the carbon clean as my experience for sheer improvement was way above expectations. I will use again and may even carry out yearly as a preventative maintenance on my cars as they all clog. The treatment makes my car feel like new.

I had my car cleaned by a great guy at ford fest at Santa pod, iv been thinking about doing this for ages, now I have done it I will never look back, my car has 122 thousand miles on it and it drives like a brand new car and uses less petrol, would hand on heart recommend this to anyone. Great service great guy.

My car Had the treatment today. I was very sceptical it would work? . Thought I would bite the bullet and give it a go. Thanks to red he took me through the whole prossess and kept reassuring me it would work. Well I didn't have much hope tbh. Well it did work just been out in the car and it's more responsive and now goes in gear as it should. Thanks Red will be recommending you to everybody I know cheers pal good work recommended for sure guys. Regards one happy chappy leeJonathan Colquhoun
Just had my BMW 1 series stage 1 done today and honestly feel an incredible difference. At first I was curious whether or not to get it done but so glad I did and was at such a good price. James explained everything to me before and after it and came out a drive with me to see the difference afterwards which was great. I can’t complain. I mainly feel a difference going from the 4th gear and up, the car seems to want to keep climbing! Anyone wondering it’s a 1 series 120d 2.0l diesel which went from 184- 220 bhp. Will definitely pass on friends and family to this guy and hopefully use his carbon cleaning service at some point. Fantastic service! Thanks James.
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
