Hi,
to properly reset limp-home you have to follow the sequence below:
1. turn the ignition ON;
2. reset all fault codes;
3. mechanically reset limp home on the throttle (keeping the ignition ON, but engine not started)
If you reset the mechanism on the throttle before clearing related fault codes it will engage again together with fault code.
Below the text from WIS for reference.

Important
When the throttle control system is in limp-home mode, the fault is stored in the control module memory. Each time the ignition is switched on, the limp-home solenoid is activated for 1 s and then for 4 x 0.5 s to ensure that the mechanism is not reset before the fault has been rectified. Repair work must therefore be carried out in the following order:
1. Rectify the fault.
2. Delete the DTCs.
3. Reset the limp-home mechanism.
If this sequence is not followed, it is highly likely that the car will leave the workshop with the throttle control system still in limp-home mode. When the system detects that it is in mechanical limp-home mode, diagnostic trouble code P1260, P1263 or P1251 will be generated.
