Did you try this ??
Whilst running the engine after a 20 mins warmup - time the F1 pump interval in Neutral and then in 1st with foot on brake.
Don’t change any components based on faults codes alone......
The above meaning the Launch system and others are just mass produced number displays , the manufactures of these devices just sign up to an expensive database of the vehicle diagnostic functional specifications then write the code.
We are the designers and supplier of the EasyMAS system and agree the other systems available on the face of it look very promising and are what they are.
EasyMAS though has been driven using Maserati vehicle knowledge based on problems facing many owners. Our system takes in the numbers and checks them against the vehicles specifications and known issues.
No Maserati ECU can self-diagnose to a point of 100% accuracy based on fault codes alone , it’s a best guess and why many times components are changed by main dealers and after driving home with your wallet empty the fault returns.
So in this case it may just be the “Clutch position sensor” but other operational tests need to be performed like the timing test at the top of this post.
We have seen the same problem resulting in new battery, ECU, clutch position sensor, pump, relay, accumulator, position potentiometers, etc etc. The actual fault was a loose bypass screw on the hydraulic valve pack.
