Fuel Injection System

Fuel Injection System

• Fuel hoses in the engine compartment may only be secured with spring type clamps appropriate for the model type. The use of clamp or screw type clips is not permissible.

• Ignition must be turned 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 will 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 must then be adapted as necessary.

• To conclude work, check the Diagnostic Trouble Code (DTC) memory of the ECM, erase all DTC entries which may have occurred during the tests and repairs. If the DTC memory was erased, generate a readiness code. refer to "Guided Function" in the vehicle diagnostic tester.

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

• When the drivers side door is opened, the fuel pump is activated for 2 seconds so that pressure builds in the fuel system. This improves comfort of engine start-up behavior.
