BMW E60 models utilize an electronic system to monitor the pressure in your tires. This is due to regulations by the US government and updated safety standards.

The tire pressure information is used to notify you of a low tire pressure condition. If a tire loses pressure, a warning lamp is illuminated in the instrument cluster and a warning chime sounds. This is a very helpful system. If you have a tire puncture and are losing air, you will be notified, therefore allowing you to immediately pull over and reduce the damage to the tire. Any time you have a warning message related to tire pressure, immediately pull over and check all four-tire pressures. If you had a low tire and repaired the problem, you will have to reset the tire pressure monitoring system. This can be done easily through your iDrive menu.

When checking air pressure, make sure you use a plastic valve stem cap. A metal one can seize onto the TPM sensor and damage it. This applies to TPM sensor equipped vehicles.

There are two systems used in BMW E60 models, FTM (flat tire monitor) or TPM (tire pressure monitoring).

Wheel speed FTM: In this system, fitted to most 2004: 2005 vehicles, tire pressure is monitored by ABS wheel speed sensors. The ABS / DSC control module compares rotation speeds at all four wheels. In case of pressure loss in a tire, the rolling radius and therefore rotation speed of the wheel changes in relation to the other wheels. The inflation differential is inferred indirectly through the tire speed differential. The control module detects this condition and illuminates a warning light in the instrument cluster.

Sensor style TPM: In this system, gradually introduced in vehicles starting with 2006 models, tire pressure is measured directly using an antenna mounted in each wheel. This antenna communicates with a centralized module via separate receiving antennas located near each wheel.

The easiest way to tell the systems apart is the style of valve stem you have:

Resetting the tire pressure system:
Resetting the tire pressure system: Read the entire procedure before beginning.

Resetting the tire pressure system: Read the entire procedure before beginning. Once read, it will be easier to follow the steps. Start your engine but keep the vehicle in Park. Press the iDrive menu (red arrow) button. Then press the iDrive controller down (green arrow) to select setting menu.

Select: Vehicle setting (red arrow).

Then choose YES (red arrow) by pressing the iDrive button.

Then choose YES (red arrow) by pressing the iDrive button. Once the button is pressed to select YES, drive your vehicle to reset the system. If the system will not reset, check the TPMS system for fault codes using a BMW scan tool.
