Might get the garage to fit the replacement potentiometer at the same time if it has arrived.

If you post up your short / long term fuel trims at idle i can advise if they are healthy, group 033 ad 034 screen grab.
Make sure you have some miles on the car since the last time you cleared codes in engine module group as is reset when this happens.
