This further development offers, on the one hand, as before the option to heat up the wax through the coolant, while on the other hand it also offers additional electrical heating.
This combination means that the temperature difference range can be configured to be much larger. In other words, the working element's electrical heating feature is actuated under certain engine load conditions. These are defined by parameters and filed in a characteristics map in the electronic engine management.

Note:
As from a difference in speed of more than 7 rpm
between the smallest and the largest value, it is
to perform a manual compression test and a
cylinder leak test on all cylinders to enable
the fault to be localized.

Beim 451 geht die Diagnose ausschließlich über den CAN-Bus (500 kBit/s). Das heißt, das jedes Steuergerät über den Bus angesprochen wird, der Vorteil ist: Schneller
in der Kommunikation zwischen Tester und Steuergerät, schneller beim Programmieren und Codieren
Am Kombi hängt der CAN C (500kBaud) Bauteile siehe PPT,
Wichtig:
Das Fahrzeug besitzt keinen LIN Bus, wenn ab Werk nicht folgende Optionen verbaut wurden:
