C5 2009 2.0HDI gearbox faulty

[martin737]

Good afternoon Colleagues,

I have the problem on my C5 2009 2.0HDI automatic gearbox. Couple weeks ago my Citroen started throwing me error "Gearbox faulty" after it comes "ESP/ASR fault" and ofc "service mode", sometimes engine turning off my itself. After turning off engine and waiting 3-5mins both faults disappears and everything looks working smoothly. These faults started appearing more often last days.
These faults appearing 1-2 times per week. Tried diagnostics, but when we do not have these faults, we do not see where is the problem.
Has anyone got anything like this? Where could be a problem? Maybe gearbox software updating would help on this.

Will wait any opinions. Thanks.

You really need to provide us with the actual fault codes. If you are using Diagbox, these will be stored or memorised in the fault logs. As there are many, many possible faults with either the ESP or the Gearbox, we really need to know what the fault is or you could be going round in circles, especially as the systems are interlinked.
