The BMW tire pressure sensor is one of the top sensors available. When you notice the tire pressure sensor going off, there might be some problems in your vehicle. What can these problems be, you might ask.
For starters, the pressure in the tires may not be accurate. Also, the tire pressure sensor might go off if there is any penetration. Moreover, the sensors might also be damaged due to several causes. You need to check what type of problem you are facing.
However, if you have little to no idea regarding this topic, fret not. This article contains almost everything there is to know about this topic.
Why does my Tire pressure warning keep coming on BMW?
There may be several reasons for this. First of all, the tires may not have the correct pressure. Moreover, there is also a possibility of damage to either the tires or the TPMS. Let us discuss the probable reasons in detail.
- Tire pressure: In most cases, the tire pressure warning keeps coming on your BMW due to low tire pressure. Your tires must have a certain pressure to avoid accidents while you are on the road. However, the tire pressure decreases over time. So, in case any of the tires are not in optimal condition, you will see the tire pressure warning.
- Damage or Accidents: While driving on rough surfaces, your tires may be damaged due to the coarse aggregates or even nails lying around the road. This will result in the lowering of tire pressure. As a result, the tire pressure warning on your BMW will turn on.
why is my BMW Tire Pressure Sensor Keeps Going Off but tires are fine?
Sometimes, the tire pressure light can keep coming on even when your tire pressure is in optimal condition. Well, this can be annoying. But, there are some reasons for which it can happen.
Firstly, the TPMS needs to be reset after you have ensured proper tire pressure. You can access the tire pressure monitor from the main menu. After you’ve ensured that the tire pressure is alright, you’ll need to do the following:
Start the engine and drive the car at 20-50 mph for a few minutes. You’ll see that the tire pressure warning will turn off after some time.
Secondly, your tire pressure monitor system can also be damaged. This can happen due to numerous reasons. For instance, the TPMS may be corroded or broken. In those cases, you will get incorrect readings and your tire pressure light can keep coming on.
Thirdly, there may be problems in the connection of your TPMS with the power supply. The tire pressure monitoring system cannot function properly without power. So, this can also be a cause of the tire pressure light coming on even when the tire pressure is fine.
Moreover, TPMS has a specific life cycle. When the system reaches that point, it can give incorrect readings, which can lead to the tire pressure light not turning off.
How long does it take for TPMS to reset BMW?
To reset the TPMS of your BMW, you need to first inflate the tires to their proper pressure. You can find the proper pressure for your tires on a placard. The placard is generally located on the door jam of the driver’s side.
After you have inflated the tires, you will need to start the engine and drive for around 10 minutes at 50mph, which we mentioned previously.
Then, you will see the tire pressure sign turning off. This indicates that the TPMS is reset.
How long do BMW TPMS sensors last?
The life cycle of the BMW TPMS sensors is not fixed. There is an integrated battery in each of the TPMS sensors. Unfortunately, these batteries are not replaceable.
In some cases, the sensors last around 3 years whereas in other cases, the sensors can last up to more than 10 years. To sum it up, the average life cycle of a TPMS sensor is expected to be around 5 to 10 years.
How Do I Know If My TPMS is bad?
Well, there are a few things that can indicate whether the TPMS system is bad or not.
The first thing you need to look out for is dead batteries. Moreover, Checking for corrosion or damage is extremely important. Also, the fuel consumption of your BMW will increase.
Furthermore, the tire pressure monitor will give indirect readings, In addition to that, the deflated tires will cause handling concerns. But, you wouldn’t be able to notice it if the TPMS is bad.
Can I still drive with a tire pressure warning?
Although it is not suggested, you can drive a few miles if your tire pressure is slightly below the recommended pressure. However, it would be better to inflate the tires as soon as possible. In case the tire pressure is too low, you must not drive your BMW.
This may cause tire failure, and in the worst case, a blowout. Hence, to avoid such risks of accidents, inflating your tire would be the best choice.
