General Information

General Information

• The Mass Airflow (MAF) sensor (G70) is no longer installed from MY 2009. The Intake Air Temperature (IAT) sensor (G42) is installed on the intake manifold with the intake manifold pressure sensor (G71).

• If fuel supply system was opened, the system must be bled before starting the engine. Refer to => [ Fuel System, Bleeding ] Service and Repair.

• Fuel hoses in the engine compartment may only be secured with spring type clamps, Allocation, refer to the parts catalog. The use of clamp or screw type clips is not permissible.

• Ignition must be switched off when disconnecting the battery. Obtain the radio code for radios with a anti-theft code before disconnecting the battery.

• Observe the safety precautions after connecting the battery.

• For trouble free operation of the electrical components a voltage of at least 11.5 volts is necessary.

• Do not use sealants containing silicone. Particles of silicone drawn into the engine, will not be burnt in the engine and damage the oxygen sensor.

• If the engine only starts briefly and then shuts off again after troubleshooting, repairs or checking of components, it may be that the immobilizer is blocking the Engine Control Module (ECM). The ECM may have to be adapted. Refer to the vehicle diagnosis, testing and information system.

• It is possible that the control module will recognize a malfunction and store a Diagnostic Trouble Code (DTC) during some tests. Therefore after completing all checks and repairs the DTC memory must be checked and if necessary erased.

• Vehicles with an airbag are equipped with an emergency fuel shut off system. It reduces the risk of fire in a collision because the fuel pump relay switches the fuel pump off.

• When the driver side door is opened, the Fuel Pump (FP) is activated for 2 seconds so that pressure builds in the fuel system. This improves comfort of engine start up behavior.
