2012 RS SE5 with error codes P0991 & C1282 - any ideas?

[oscarolmi1966]

Hi everyone, I'm Oscar Olmi and I'm writing from Italy, I would kindly need some advice:
I own a Can Am Spyder RS 2010 bought in July 2023 with 10,000km, the bike presents me with 2 problems,
1 - "Check Brake fault" and it was the brake oil pressure, bled the calipers and ABS, now it brakes very well, checked the sensors on the brake pump and they are ok (STOP sensor switch and SWITCH sensor/low pressure brake pedal), but error persists.
2 - when cold the motorbike gives me the "check transmission" error, I state that the motorbike works correctly, when hot the transmission problem disappears, I had the dealer check it and they changed the SE5 hydraulic transmission crankcase and blipper sensor and for a while over time the transmission problem no longer occurred.... now with winter temperatures it returns.

Checking errors stored with a manual procedure I found the following: P0991 C1282 on the motorcycle display.
Does anyone have any ideas before you think about reselling the bike?? I would be very sorry because it's very funny.
Thank you
Olmi Oscar
