IMPORTANT:

During the control unit reset, RST appears in the lower right corner of the TECH 1 display.

In the X 14 XE and X 16 XE engines (MY '95) it may happen that the control unit does not perform a reset. In this case: disconnect control unit from wiring harness.

Note:

The learned values are reset to allow the knock behaviour of a petrol engine to be evaluated. The mechanic/  Service technician can determine the engine knock on a test drive and from the reaction of the control unit.
