Recent vehicles are more and more equipped with new technologies, apart from the comfort of use it can bring, technology as well has the advantage of saving fuel or reducing the pollution emitted by our vehicles. This is precisely the subject of our content of the day, we are going to look at the complications of the lambda sensor on BMW 2 Series , this sensor as well known as oxygen sensor plays an important role. To find out, first, we are going to find out what a lambda probe is utilized for, then, what are the lambda sensor complications on BMW 2 Series and how to fix them.

What is a lambda role on BMW 2 Series?

So we start our content with the interest of a lambda sensor on BMW 2 Series , we will first discover what is the function of this probe and then how it functions.

Role of a lambda sensor on BMW 2 Series

First developed by Volvo in the 1970s, it began to appear on our cars in the 1990s with the first EURO 1 emission requirements. Also called oxygen sensor on BMW 2 Series , its goal is to control the amount of oxygen in the exhaust gases, this will enable the engine unit to adapt the air/fuel mixture to decrease the pollution emitted by the car and reduce the car’s fuel consumption.

Lambda sensor operation on BMW 2 Series

Before describing you the different complications of lambda probe on BMW 2 Series , we will look a little more in outline at its working to allow you to discover exactly how it functions and thus to consider more serenely the correction of a problem related to it.
As we informed you, a lambda probe has the job of controlling the amount of oxygen present in the exhaust gases . One could naively think that this data is determined upstream of the combustion but it is on the contrary measured at the engine outlet . With the EURO 1 standard there was only one lambda sensor required before the catalyst, but with the arrival of more drastic requirements there are now 2 lambda sensors, one before and one after the catalyst . The interest is to have more exact data by compiling the two probes. These data are sent to the ECU which will adjust the quantity of air and gasoline injected into the engine unit to optimize the combustion .

.
At last, we are now going to attack the part you are absolutely most enthusiastic about this content, how to proceed if you have a lambda sensor issue on BMW 2 Series . In a first step we will see how to find a lambda sensor HS and in a second step how to replace it.

How to know if a lambda sensor on BMW 2 Series is HS

.
It is important to know that a lambda sensor has generally speaking a lifetime of 150 000 km , this statistics can differ according to the year of your BMW 2 Series, your driving, and the good performance of your engine unit. A poorly looked after engine unit that produces unburned gases may permanently corrupt your lambda sensor. One of the clues that can warn you of a faulty lambda sensor on BMW 2 Series might be the engine unit light comes on, if you want to turn off the engine light of your BMW 2 Series, do not hesitate to visit our dedicated content to discover the process to follow. The only effective technique to be sure that you have a lambda sensor issue on your BMW 2 Series and to pass your car to the diagnostic case, for that do not hesitate to consult our guide which explains you BMW 2 Serieshow to read the fault code of a BMW 2 Series. Take note that if you have complications with one of your lambda sensors, the only solution to correct them will be to replace the faulty sensor.

How to replace a lambda sensor on BMW 2 Series?

And finally, we are going to concentrate on the correction of lambda sensor problems on BMW 2 Series , by explaining how to replace a lambda sensor.

The replacement of a lambda sensor is quite very easy to accomplish and you will have the ability to do it yourself with a lowest of tools and mechanical expertise. A lambda sensor is worth between 25 and 50€ , it is better to replace the 2 lambda sensors present upstream and downstream of your catalytic converter because if one of them is faulty the second one risks to drop you fairly quickly. To replace it, it will be required to put your BMW 2 Series on candles and at the level of your catalyst unscrew your probes, disconnect them, reconnect them and screw the new ones . Once re-connected, you should not have any more complications with your lambda sensor on BMW 2 Series.
