I can't seem to find an answer to this around the forum so am posting my first question.
Having just de-badged my S-Type (wish i had done before, a lot cleaner look and no dirt harbours ) ) , I want to clean up the boot switch (trunk badge switch) where the growler head is as some dirt and moisture seems to have got behind the plastic obscuring the head.
Does the plastic top pop off this to clean behind or do i have to find a new switch in better condition? (about £15 on ebay).

 

The instructions on removing the boot plinth are contained in JTIS.

What you are describing suggests another switch may need to be fitted as the growler is part of the switch button face. If the one listed for £15 is in good condition, that may be your answer.
