Chauffeur ignoring volume for this appliance (5)
I believe the answer is:
drier
'this appliance' is the definition.
(drier is a kind of appliance)
'chauffeur ignoring volume' is the wordplay.
'chauffeur' becomes 'driver' (I've seen this before).
'ignoring' is a deletion indicator.
'volume' becomes 'v'.
'driver' with 'v' removed is 'DRIER'.
'for' is the link.
(Other definitions for drier that I've seen before include "More dull" , "Flatter" , "Less wet" , "affected by sunnier climate" , "Machine giving spin" .)
