Hi,
I'm trying to perform a clutch calibration on a Fiat Ducato with a Comfortmatic gearbox.
I've also tried to perform a clutch drain (clutch bleed).
The clutch bleed fails with a critical software error.
The clutch calibration just drops out without processing.
There is an error code that I cannot clear, I assume I need to complete a calibration to remove the error code.
Anybody have any ideas of how to fix or get around these problems?
Is it something I'm doing wrong?
Any help or guidance would be appreciated.
