2017 - R ninet
all attempts to "Reset the adaptation values for the throttle twistgrip sensor" are unsuccessful.
not sure why I never mentioned previously - there is a TIPS document for wires never clipped into the multiplug housing on the wires to the twist grip - affected loads of different BM modules basically they forgot to make the looms with enough care and some pins are falling out so never connect up fully when the two sections go together

SITUATION
When diagnosing fault codes below, technicians erroneously condemn the electronic throttle grip, which analyses show is rarely the culprit.
0x3A13D7 throttle grip sensor, short circuit to ground (duct 1)
0x3A13D9 throttle grip sensor, short circuit to ground (duct 2)
When either or both of these faults are triggered, the vehicle goes into emergency operation and a fault message appears in the instrument cluster.
These faults are often sporadic or not permanent and a faulty plug connection can often cause this condition.
PROCEDURE
When diagnosing the cause of these fault codes, perform a guided diagnosis with ISTA.
During the guided diagnosis, one of the steps is checking the plug connection S177*1B to the electronic throttle; this plug connection should be examined closely.
