I brought the car into a shop and now there are telling me the clutch is done and needs replacing.

I´m a bit confused because the clutch is working properly until the car is warm... how much does the clutch job cost in yur area for comparison?

Thank you.

Did they give you the clutch wear reading? In all honesty, if the CPS is failing (and it certainly seems to be) then not changing the clutch while it is apart would be false economy.

its done is the feedback or reading. The values he spocked about is 16mm new and mine has 21mm. In his expierence the clutch is worn and thats why the sensor don‘t provide a correct reading

Clutch plates were about £700, the costs are in labour and the extras like release bearing, spigot bearing, f1 position sensor and flywheel.

Car has under 30tkm... that is also my thoughts to be honest. I don‘t get it why the car is working properly when it‘s cold.
After warming up there is no information avaiable from the f1 sensor - Code p1710

Best to pull it apart then visual inspect the clutch friction and measure. Maybe it already had a clutch as 30km about the life of one anyway depending the way it has been driven. Readout the live data on clutch wear when cold to get an idea of wear. The position sensor is the most definitely the culprit here. Bit like a crankshaft position sensor they break down when warm meaning if the engine doesn't know where the crank is in relationship to the cams the engine will not spark. Similar scenario: if the TCU doesn't know where the clutch is; it will command the PCM to shut the engine off.

Changing the CPS is not an expensive job. I would start there.

Gearbox, torque tube and bellhousing out and about £250 for the part so you may as well do the clutch.

The garage mentioned the same... Changing the sensor is nearly the same as a clutch job. Thats why they recommend to change the clutch in general when you are in there. In my case the clutch should also be gone, so they recommend to do it all.

They quoted 5-7k... for a specialist which have it done several times I think it´s a little bit expensive.

If the CPS loosing connection when the car gets warm what happend there with the sensor? Heat should expand things an not shrink?! I´m still thinking it´s a connection fault somewhere. And I´m already thinking about getting the car back and measure the oldstyle by myself and maybe doing the clutch job in my garage during winter, if the quote will stay the same...

You need the Maserati SD3 reader to set the clutch up, not cheap, dearer than the clutch job, much dearer....

I just paid 3000 for a Maserati main dealer to do the clutch, sensor etc. what surprised me was that the clutch needs balancing.

None of the clutches sold now should need balancing. With the early versions (up to "component 9044" according to the service manual) has a loose intermediate plate which could be removed along with the friction plates to allow the housing / pressure plate to be dynamically balanced on the flywheel attached to the crank.

The newer clutches have additional straps/springs (often called "tangs" on here but not to be confused with the pressure plate springs which are also called "tangs") to hold the intermediate plate in place (probably to stop the plate chattering at idle when open) so the friction and intermediate plates can't be removed for balancing. If the straps were removed, it would almost certainly put the clutch out of balance when reassembled so with the new clutches, you need to rely in the factory balance.

If a blance is attempted on a new style clutch, it is likely to make the balance worse.
