Gearbacks, STG says: load signal error MSTG

Hello.

sometimes have the problem that it is switching from 3. ==References== Gang's jerking. Each time the gearbox then makes a short pause for thought. I.e. I'm expecting the switchpoint now, but it takes a moment longer and then it's jerking.
I had this problem all the time before my gearbox died. Since a new gearbox and a new MotorSTG have been installed, the whole thing is still quite rare.
Today, however, it was time again. Then I did not switch off the engine and immediately read out the fault memory from the transmission. And in fact, there's a mistake:

18265/P1857: load signal, error message from the engine control unit, sporadic

There is a note in my documents: With the data levels D26, D29, and D32, the error ratios 18157/P1748 and 18265/P1857 were swapped. My gearbox STG has the data level 1314, so the error code should not be switched.

The above error is detected by the motor control unit and transmitted to the gearbox STG via CAN (together with various other data). There is no error in the MotorSTG itself. The cause of the error is "wrongly coded or wrong engine control unit". But now the error is rare, so it is sporadic. And there's the catch. Either the STG is coded incorrectly (which I have checked before) or not. But sporadicly wrong coded can't be.

So what do you do? Does anyone have an idea?

Martin
