How do I reset the tire pressure monitor on my BMW 4 Series?

I just replaced my tires and the tire pressure monitor is still showing an incorrect reading. How can I reset it?

To reset the tire pressure monitor on your BMW 4 Series, first make sure all tires are properly inflated. Then, start the car and drive at least 20 mph for a few minutes to allow the sensors to calibrate. If the monitor still shows an incorrect reading, try disconnecting the car's battery for a few minutes and then reconnecting it. This will often reset the system and fix any issues. If the problem persists, it may be a faulty sensor and you should have it checked by a mechanic.

One trick to resetting the tire pressure monitor on a BMW 4 Series is to hold down the tire pressure reset button until the monitor flashes three times. This will force a recalibration of the system. If this doesn't work, try checking the battery in your key fob. A weak battery can sometimes cause issues with the tire pressure monitor. If that doesn't fix the problem, you may need to have the sensor replaced.

If your BMW 4 Series has a Run-Flat tire system, it's important to know that the tire pressure monitoring system can be affected by the age of the tires. If you've recently replaced your tires and the monitor is still showing an incorrect reading, it may be because the new tires have a different level of wear and tear compared to the old ones. In this case, it's best to have a mechanic reset the system to ensure accurate readings.
