Note:
The idle speed can be reprogrammed, allowing the nominal
idle speed to be changed by 50, 100 or 150 rpm.
Carry out relevant TECH 1 adjustment (sect. 3.2.5.1)
and ECU control (sect. 3.2.7.1).
If the intake air temperature (cf. Data List No. 05)
is higher than 50 °C / 122 °F, the nominal idle speed may
increase by up to 100 rpm.
If the battery voltage is very
low when the engine is running at idle speed (between 12.0 and 12.2 V),
it is possible that the Motronic control unit increases the idle speed by up
to 50 rpm.
