BMW X5: Engine-Off / Coasting
Principle
Under certain conditions the engine is automatically decoupled from the transmission in the D selector lever position. The vehicle continues traveling with the engine idling to reduce consumption.
Selector lever position D remains engaged.
This driving condition is referred to as coasting.
Under certain conditions, the engine will not be operated at idle while coasting but switched off automatically in vehicles with Mild-Hybrid technology.
When the engine is switched off, the lettering READY is displayed in the instrument cluster.
The vehicle continues to coast without consuming fuel. This driving condition is referred to as engine-off coasting.
As soon as the brake or accelerator pedal is depressed, the engine is automatically coupled to the transmission again.
General information
Coasting is a component of the ECO PRO driving mode.
Coasting is automatically activated when ECO PRO driving mode is called via the Driving Dynamics Control.
A proactive driving style helps the driver to use the function often and supports the efficient effect of coasting.
Functional requirements
The function is available in the speed range from approx. 16 mph/25 km/h to 100 mph/160 km/h.
The function is active if the following conditions are met:
- The accelerator pedal is not depressed or the accelerator pedal is released.
- Brake pedal not depressed or only slightly depressed.
- The selector lever is in selector lever position D.
- Engine and transmission are at operating temperature.
- Active Cruise Control with Stop&Go function, ACC, not activated.
Operation via shift paddles
Principle
The coasting driving condition can be influenced with the shift paddles.
Activating/deactivating coasting via shift paddles
1. Shift to the highest gear by pulling the right shift paddle.
2. To activate coasting mode, actuate the right shift paddle again.
To deactivate, actuate the left shift paddle.

Fuel System Testing
Fuel systems need to be checked for proper fuel pressure as well as
sufficient volume. When diagnosing fuel
system complaints, you must take into account the type of fuel system and how

Fuel Volume Testing
Some driveability concerns are related to incorrect fuel volume. Vehicles
with lack of power complaints and
mixture related fault codes may have insufficient fuel volume supplied to the
fuel injection system. These
vehicles may actually pass a fuel pressure test.
