General Repair Information

• 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 clamps is not permissible.

• Hose clip pliers (VAS 6340) or spring type clip pliers (VAS 5024A) are recommended for installing spring clamps.

• The ignition must be switched off when disconnecting the battery. Obtain the radio code for radios with antitheft coding before the disconnecting battery.

• Observe the safety precautions after connecting the battery. Refer to.

• 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, repairing, or checking of components, it may be that the immobilizer is blocking the Engine Control Module (ECM). The ECM must then be adapted if 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.

• 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 opening the driver door, the fuel pump is activated for 2 seconds to build pressure in the fuel system. This improves comfort of engine startup behavior.
