1. Vehicles with manual gearbox and xDrive:

WARNING: This page does not describe the selected car, but rather 21 other vehicles, including the 2013 BMW 328xi, 2013 BMW 328i, 2012 BMW 328xi, 2012 BMW 328i, and 2011 BMW 328xi. However, it is still accessible from the selected car via links, so may be relevant.

IMPORTANT:

Before driving onto the dynamic brake or power analyzer), switch off the Hill Descent Control (HDC) and keep it switched off while testing the brakes.

The HDC indicator lamp must not light up! It is possible for the HDC indicator lamp to go out or not to light up even when HDC operation is activated. This may be because HDC is temporarily unavailable due to high brake temperature.

Do not select a gear and do not accelerate. Otherwise damages occur to the test stand or vehicle!

Pressing the accelerator pedal causes the multi-plate clutch in the transfer case to close, even in Neutral. Consequently the stationary axle is also driven, and the vehicle surges from the analyzer. Because the front and rear axles are now coupled, the axle to be tested then increases the brake force until the analyzer is shut down.
