| General notes on injection |
| t
| The engine control unit is equipped with self-diagnosis. Before carrying out repairs and fault finding the fault memory must be interrogated. Also the vacuum hoses and connections must be checked (unmetered air). |
| t
| Fuel hoses in engine compartment must only be secured with spring type clips. The use of clamp or screw type clips is not permissible. |
| t
| Disconnecting and connecting the battery must only be done with the ignition switched off, otherwise the engine control unit could be damaged. |
| 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 immobilizer which is blocking the engine control unit. The fault memory must be interrogated and if necessary the control unit matched → Chapter. |
| t
| During some checks it is possible that the control unit will recognise and store a fault. Therefore after completing all checks and repairs the fault memory must be interrogated and if necessary erased → Chapter |
