| General notes on injection |
| t
| Fuel hoses in engine compartment must be secured only with elastic clips (as supplied by the factory). The use of clamp or screw-type clips is not permissible. |
| t
| The battery should only be disconnected with the ignition switched off. If the vehicle has a security-coded radio, obtain the correct anti-theft code number before disconnecting the battery, if necessary. |
| t
| For trouble-free operation of the electrical components a voltage of at least 11.5 V is necessary |
| t
| Do not use sealants containing silicone. Particles of silicone drawn into the engine, will not be burnt in the engine and damage the Lambda probe. |
| t
| If the engine starts, runs for a short period and then stops, after fault finding, repairs or component tests, then the fault may lie with the immobiliser blocking the engine control unit. In this case the control unit must be adapted. |
| t
| Certain tests may lead to a fault being detected by the control unit and stored. Therefore, after completing all checks and repairs, read the fault memory and erase if necessary → Chapter. |
| t
| Vehicles with an airbag are fitted with a crash/fuel shut-off. It reduces the danger of a fire in a crash as the fuel pump is switched off via the fuel pump relay. |
| t
| When opening the driver's door, the fuel pump is activated for 2 seconds to build-up pressure in the fuel system. By this the starting behaviour is improved. |
