Can you not just tell the warranty company that the garage need to do this work and that the car is still with the garage waiting for the authorisation number before starting the work ? Obviously you will have to clear this with the garage first before telling the warranty company.
Thats how I've done it in the past when I need the car back the same day, my warranty company never get straight back to the garage with the number !
