Goes off for servicing (7)
I believe the answer is:
repairs
'goes' is the definition.
The definition and answer can be both acts as well as being plural nouns.
Perhaps you can see an association between them that I can't see?
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for repairs that I've seen before include "Withdraws" , "Restores" , "Mends, fixes" , "makes good" , "Doctors" .)
