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:
24 -D 55
