Servicing ignition part
=> Repair group 28
Notes:
-
◆ Fuel hoses in engine compartment must only be secured with spring type clips. The use of clamp or screw type clips is not permissible.
-
◆ The control unit for the fuel injection and ignition system is equipped with a fault memory. Before carrying out repairs, adjustment work and fault finding the fault memory must be interrogated and the vacuum connections checked (outside air).
-
◆ Components marked with * are checked via the self diagnosis.

-
◆ Components marked with ** are checked via the final control control diagnosis => Page 01-72
.
-
◆ For trouble-free operation of the electrical components, a voltage of at least 11.5 V 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 Lambda probe.
-
◆ Do not use contact sprays or similar agents in the area of the connector for Lambda probes. To function correctly Lambda probes require reference air, which they receive via the cable. If contact spray gets into the Lambda probe via this path it will lead to damage/malfunctions.
-
◆ During some checks it can happen 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.
