Checklist, general symptoms


Checking

Use Tech2 to check the following readings and adaptation values.

Conditions

- The coolant temperature must be normal (>80°C) and the engine idling.

- The A/C system must be off (turn A/C to OFF or press "Econ").

- Fault codes must not be deleted before the values have been read.
