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 live in Newbury and Matt doesn't normally cover that area. He was more than happy to find a time and a location that we were both happy with. Emailed me with directions and a map link showing exact meeting point. Cleaning took about 30 mins. Matt explained the process and readings on his machine. Afterwards, my 135i showed improved throttle response and a smoother acceleration. Definitely worth the £90. Will get this done once a year now.Di Riddell
Very speedy service, phoned on Saturday, arrived Monday morning and car back up and running Monday lunchtime! James is a lovely guy, very easy to chat to and happily explained the process and readings. Car was in limp mode before the process and now working again so very pleased. Wouldn't hesitate to recommend this professional & friendly company.

I would recommend James in a heartbeat. He is extremely knowledgeable and fixed my DPF issues on my Volvo V50 in less time than just one of the many visits I made to other garages in the Borders who didn't have a clue how to resolve the problem. James arrived exactly when he said he would, fixed my car and charged me less than half what I had been told to expect by so-called experts. James really knows his stuff and I am delighted with the excellent service James provided. He does what he says he will when he says he will do it and I was delighted with the costs of his service. What more can you ask. My V50 is running like a dream again all thanks to James.

Had our DPF professionally cleaned yesterday, and the garage mentioned an injector fuel fault code! I have no idea about cars at all so I assumed the worse thinking they were going to have to be replaced costing hundreds! Found this company and thought I'd give them a go as the reviews were all brilliant! Booked an appointment online for next week, Matt phoned within an hour and said he could come over this afternoon which was brilliant! He explained everything to me making me understand it all more... he also found the air filter was snapped and would need to be replaced, he showed me how to do it so I could go and buy one, cost me £7 and I did indeed manage to do it myself instead of going to a garage and paying £50! Lovely guy, and a lovely service, car feels amazing and I will
Be using you again! As a woman I'm very wary of garages/company's but I couldn't recommended you any more! Thank you!!Alastair Chapman
I have just had James up doing a remap and carbon clean on my land rover discovery td5 he was bang on time and went through the process of the clean with me and explained how it all worked. Once he had finished I took the car out and within 100yds I could feel a huge difference. Engine is now so smooth and quiet and also alot more responsive with what feels like heaps of power. I can't recommend this process enough and James was brand new. Even thinking about getting the freelander done too. Cheers again 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
