I was interveiwed under caution about physical abuse to a client,it was unfounded and I returned to my work after.will this go down on a enhanced check

First, its not a good idea to piggyback your question on another thread. To avoid confusion I've moved your post to its own thread.

It depends on the circumstances. Without more details about who interviewed, what type of work you do or what type of check is being made its hard to answer.
