Volkswagen Golf III, AFN engine, 235,000 km (approximately 146,000 miles).

Why does column 2 of form MWB 5 ("Starting Quantity") show a value before the start?
Should the value be 0 mg/stroke instead of the value used to initiate the start process?
A value may only appear after a successful start (or possibly during the start process).
Does the process start with a long organ sound? Is the resulting value always...?
Value indicating whether the start was successful?

Sure, here's the translation:

"The MWB 8 displays a [something] under 'Driver Preference' before starting."
Value not equal to 0 (when the accelerator pedal is released!). What does this value represent?
to mean?

Regards, Klaus.

Hello,

Wert, mit dem der Start erfolgreich war ?

Good question icon_wink.gif. In the case of AFN, it appears that a starting value for the injection quantity is determined depending on the coolant temperature, and this value is then increased during "cranking" until the engine starts or the start attempt is aborted.

Nothing. icon_wink.gif It's simply the default value for this operating point.

Best regards, Rainer.
