Service it first. Then cloud save. If it won't let you cloud save go stick some stickers on a different car. Anything to differentiate the save from the last. Then save after servicing. The counter will count down as normal. When you come back, cloud restore, but the service will remeber it's place.

When you finish a challenge (do the last event for that day) you can't service it until the next day event starts. So depending on if you finished first and had the engineer or not your first task of that day as soon as midnight happens is to put the car in service and go to bed.

This is annoying as some of the last challenges of a day might not even be ones you can finish first in.
