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.

Can not fault the service one bit. The service I have been giving is the best I have experienced the guy is not in the for the money he is straight up and tells u exactly everything u need to know from start to finish he even come out in his own time coz i thought the fault with my car was something he done but in fact I had nothing to do him very polite and genuine guy highly recommend to anyoneAleem Khan
Guys, make sure you try this out.. Ive just taken my Audi A7 for a drive on the motorway and you can hear and feel the difference. I didnt think my car was sluggish to start with but since having this done, I think its sparked new life into the engine. Going to get this done yearly now without fail..

Had My Girlfriends VW Passat 2.0l Tdi Sport Remapped Today By James.. Really Nice Friendly Guy, He Explained The Whole Process And If You Were Not Happy With The Results He Would Put It Back To The Way It Was.
No Need For That Though...The Car Now Has Added Mid Range Punch That It Just Seemed To Lack. Good To Have The Extra Power For Overtaking Safely.
Really Happy With The Results.And You Notice The Different Instantly....
This Is My Girlfriends Second Passat Estate And It Just Didn't Feel As Sporty As Her Last One Which Was Basically The Same Engine etc etc..I Noticed Her New One Had Been Into A Vw Garage To Get The Software Recall After The Emissions Scandal Previous To Buying It And I Don't Know What They Done To It But It Lacked In Power Especially When Trying To Overtake . Not Now Though

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
