• There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

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

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?? :dontknow:
 
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.
