I think the Bentley is being too lenient in this case.

What brand/model of oil filter is your car running on?  A cheap filter
can cause undue lifter tapping noises.  A few seconds of lifter tapping
is OK after a cold start, but it should quiet down soon after that.
If you are using the proper filter (OEM Audi, or the appropriate Mann
or Mahle brand units), and the lifter still makes noise when the engine
is warmed up, then the lifters should probably need to be replaced.
