- Fuel hoses in engine compartment may only be secured with spring-type clamps. The use of clamping collars or screw clamps is not permitted.
- Components marked with * are checked via On Board Diagnostic (OBD).
- Components marked with ** can be checked via output Diagnostic Test Mode (DTM).
- For the electric components to work properly, a voltage of at least 11.5 V is required.
- Do not use any silicone sealant. Traces of silicone components which are sucked into the engine are not burned there, and they damage the oxygen sensor.
- It is possible that the control module will recognize a malfunction and store a DTC during some tests. Therefore, after all tests and repairs have been performed, DTC memory should be checked and erased if necessary.
