EDL shut-off

Electronic Differential Lock (EDL) is deactivated at excessive brake temperature (only EDL).
Standing time (TIM):

The standing time (TIM) is used to calculate how much the brakes have cooled while the ignition is off. The ABS control
module -J104- receives the standing time signal from the instrument cluster.
- If nothing is displayed, press -C- button, select function 02 and check DTC memory. Repair the malfunction with the help

To read the display fields for yaw rate and
transverse acceleration while driving,
communication between the scan tool and the
control module must be terminated via the "End

After this, a value of either - 9,8 1 m/s2 or
+ 9,8 1 m/s2 will be indicated on the scan
tool display in display group 5 (use the "Read
measuring value block" function).
A plus in front of the number indicates the
affect on the sensor while driving around a
left-hand curve.

A minus in front of the number indicates the
affect on the sensor while driving around a
right-hand curve.

After reinstalling the sensor for transverse
acceleration -G200- or the combined sensor
for yaw rate and transverse acceleration,
tighten the mounting bolts to 5 Nm. Tighten
the mounting bolts for the control module for
ultra-sound sensors -J347- to 2 Nm.

Note:
Due to an error in the test card 8.0 for the
VAG1551 scan tool and the test card 5.0 for the
VAG1552 scan tool, the display for Measuring
Value Block 5, display group 4 is offset by one
decimal point. This means, for example, that a
transverse acceleration value of 9.81m/s2 is
displayed simply as 0.98 m/s2 .
