Recent vehicles are more and more built with new technologies, apart from the comfort of use it can bring, technology also has the advantage of saving fuel or reducing the pollution released by our vehicles. This is precisely the subject of our article of the day, we are going to look at the complications of the lambda sensor on BMW X1 , this sensor also called oxygen sensor plays an necessary role. To find out, first, we are going to identify what a lambda probe is used for, then, what are the lambda sensor complications on BMW X1 and how to solve them.

What is a lambda task on BMW X1?

So we start our content with the interest of a lambda sensor on BMW X1 , we will first discover what is the purpose of this probe and then how it functions.

Role of a lambda sensor on BMW X1

First developed by Volvo in the 1970s, it began to show up on our cars in the 1990s with the first EURO 1 emission standards. As well called oxygen sensor on BMW X1 , its task is to control the amount of oxygen in the exhaust gases, this will allow the engine unit to modify the air/fuel mixture to lower the pollution released by the motor vehicle and reduce the car’s fuel consumption.

Lambda sensor procedure on BMW X1

Before describing you the different complications of lambda probe on BMW X1 , we will look a little more in detail at its working to allow you to figure out precisely how it functions and thus to consider more serenely the correction of a problem related to it.
As we told 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 standards 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 adapt the quantity of air and gasoline inserted into the engine unit to optimize the combustion .

Lambda sensor problem on BMW X1

.
At last, we are now going to attack the section you are certainly most keen on this content, what to do if you have a lambda sensor problem on BMW X1 . In a first step we will discover 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 X1 is HS

.
It is necessary to know that a lambda sensor has generally a lifetime of 150 000 km , this statistics can vary according to the year of your BMW X1, your driving, and the good performance of your engine unit. A poorly maintained engine unit that releases unburned gases may forever damaged your lambda sensor. One of the clues that can notify you of a defective lambda sensor on BMW X1 might be the engine unit light comes on, if you want to turn off the engine light of your BMW X1, do not think twice to visit our dedicated content to discover the process to follow. The only effective way to ensure that you have a lambda sensor problem on your BMW X1 and to complete your car to the diagnostic case, for that do not think twice to consult our tutorial which explains you BMW X1how to read the fault code of a BMW X1. Please note that if you have complications with one of your lambda sensors, the only remedy to solve them will be to replace the defective sensor.

How to replace a lambda sensor on BMW X1?

And at last, we are going to concentrate on the correction of lambda sensor problems on BMW X1 , by describing how to replace a lambda sensor.

The replacement of a lambda sensor is quite simple to perform and you will be able to do it yourself with a minimal of tools and mechanical know-how. 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 defective the second one risks to drop you quickly. To replace it, it will be required to put your BMW X1 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 X1.
