There is no cache hidden at these coordinates!!
In order to find the bonus cache, you will need to look for the bonus numbers hidden in each of the Torver to Coniston Trail caches (1-14). These numbers will give you the necessary information needed to find the final cache, which is located somewhere in Coniston village.
When you have found all of the numbers, just replace them as follows
N54º 22.(A)(D-E-C)(C+G)
W03º 04.(E-B)(D)(F-C)
Good luck & happy hunting
