Ok so received call from MAS service stated fault code 1782. Upon inspection they said code was do to having a 24.5 reading (closed clutch Position). They said the new clutches are around 90-95. On the GTS if it gets to this point it triggers the fault code goes into limp mode.
I'm having my car transported back to me tomorrow as i have a few exotic specialist here in Sacramento area that can give me a second opinion and if it is a clutch replacement they can get me a better price than the MAS dealer. The saga continues!
Okay thank you for the update. Unfortunately, I looked through the 62 pages of codes and didn't find P1782 for the gear box. I have the codes for the F430 which is basically the same for the F360, Coupes/Spyders, and GranSports. The codes go as high as 1790 but 1782 isn't specifically listed for the gear box. It might be a code they added specifically for the GTS F1 but I'm kind of doubtful.
So I am assuming they are talking about the clutch parameters for open/closed position. That data is sent by the F1 position sensor to the TCU or NCR of the car. I guess where I'm confused at is that you stated your clutch wear read out was only 35% worn or 65% remaining at 34K miles. Do you know if the clutch was ever changed out in the car?
Malfunctioning F1 position sensors aren't unheard of, actually quite the opposite. But with the Malfunctioning F1 sensor, and the closed clutch position of 24.5 you wouldn't have a read out of only 35% worn. At least that is my assumption because the data the algorithm uses is based on the parameter stored in the NCR and that's based off of what is sent to it from the F1 position sensor.
I'm thinking maybe the F1 Position sensor is shorting out and sending correct data sometimes and faulty data at others. When they retrieved the clutch wear data it must of been when they reset the car, and the sensor at that time was temporarily working. As the problem was intermittent, the F1 sensor acted up again putting the car back into limp mode. F1 sensors are kind of like Crank Position sensors. They can be affected by heat/movement when they start to go bad. Again this is my assumption.
To put your car into perspective, I have 28K on my GranSport, I'm at almost 100% clutch wear now. I do have to replace it this winter. So it's not unheard of to be replacing a clutch on an F1 car with your mileage. I just was wondering whether it had been replaced already with your clutch wear, and maybe someone didn't replace the F1 sensor when they did the clutch job in order to save $400-500 in the process.
Maybe I should also add there have been members who bought a brand new F1 position sensor and when they put it in, it needed to be replace out of the box. Few and far between but it does happen.
