NOTE: The stated values are the result of measurements of vehicles with different mileages and in perfect condition. Different values can result from diagnosis in the workshop because of mileage and environmental influence. For DME diagnosis, it is important to look at several values simultaneously and in a collective group during troubleshooting.

Example:
An important collective group is formed by the following values:
