2020 F3 Fault Codes: P194E, P278F, P0740 - any help?

[T.P.]

The Mrs got these fault codes on her 2020 F3, I can't find an up-to-date code list.
Anyone have that source? P194E, P278F, P0740

The Modules haven't changed all that much... Do these help any??

P194E
Module: TCM Bosch
Clutch is too thin.
Clutch is worn out.
Friction pads are significantly thinner than originally.
Inspect clutch & replace if necessary.

P278F
Module: TCM Bosch
Clutch Slope Low limit exceeded.
Wrong oil is used in engine.
Clutch is worn out/over-heated/glazed.
Engine torque estimation is faulty.
Verify that the right type of oil is used.
Verify that the engine is running on all cylinders.
Reline the clutch.
Replace the engine oil & Clutch Pack.

P0740
Module: TCM Bosch
Clutch torque transfer performance too low.
Clutch coefficient if friction low.
Clutch kiss-point pressure high.
Maximum clutch pressure low.
Change engine oil.
Replace clutch if friction coefficient or offset out of service limits.
Replace HCU if max clutch pressure too low.

I'd start with the simple stuff - when did the oil & filters last get changed??

[T.P.]

oil last changed first part of July 2023, 2083 miles on amsoil Metric and HF 556 so far
11,154.3 total miles on the Spyder.

After being at the dealer for a month, should have it back by next weekend, parts came in this week, all clutch parts replaced.
there was a jam nut that had come loose. needed to be sent to BEST for approval and it was.
dealer was not happy that I use Amsoil, but backed down when I showed them that they sold it to me.
This is not a friction pad issue either as they first claimed because of the Amsoil.
