1. Check actual value Coolant temperature. Plausibility
Test prerequisite

- Switch on ignition.
Status of the relevant actual values:
- Coolant temperature:Warning! Communication with ECU required.

- Fuel temperature:Warning! Communication with ECU required.
Specified value

- The actual values must be plausible.
- Temperature difference +/- [ 60° C ]
Question

- Are the actual values o.k.?


YES
The actual values are okay.Further procedure

- In the event of stored faults with a high fault frequency count or in the event of customer complaints, check lines and connectors for loose contact and corrosion..
