Background

In certain cars, vibration may arise in the body at idling speed and when the car is stationary.

Certain cars, equipped with automatic transmission, may have idling speed set too high, which may mean that the car moves forward too forcefully when lever position D is engaged.

In the case of customer complaint, the following procedures must be carried out.

Symptom description

Parts required

Procedure


1. Establish whether the car has idling speed vibration problems or a tendency for its drive to be too forceful at idling speed.

2. Adjust the engine's idling speed. Connect Tech2.

• Get Security Access (must be repeated with each adjustment attempt)

• Select "Diagnostics"

• Select "Model Year"

• Select "Car Model"

• Select "Engine Type"

• Select "Engine Management System", "Trionic 8"

• Select "Adjustments"

• Select "Idle Speed Offset"

• Adjust the idling speed, press OK.

If the car exhibits vibration problems during cold starting for example, then the speed should be increased at a minimum (10 - 30 rpm). If the problem remains at all engine temperatures, then increase the speed by more than 30 rpm.

If the car drives forward too forcefully when engaging gear, lower the speed in steps of 20 rpm.

3. If the car is equipped with automatic transmission then the customer should be informed that the tendency to creep at idling speed will increase if idling speed is increased.

4. If possible, test the car together with the customer after the procedure.
