Bosch CX gen mainboard

[Igors]

It's not possible to alter the calibration of the motors angle magnet unless it is physically removed and re-fitted in a different position. This magnet is not affected by changing the gears or their bearings. However, the motors overall magnetism can easily be affected and this is what causes issues when the motor is re-assembled and brings up a 510 error code.

yes Or get an intermediate position. when there is no 510, but the engine behaves as if the board is not from it.

My warning is not to not repair. I advise you to do it quickly and carefully.

The Gen 4 can stutter or behave as if the wrong PCB is fitted for several reasons, a common example would be dirty cadence sensor pick-up etc. It can't really be affected by working on the transfer gear box unless the armature angle magnet is deliberately moved by force, damaged or heated (People sometimes overheat the magnet while warming the aluminium housing to remove the gear spindle needle roller bearings).
Hope this helps clear things up a bit.
