s3 8l revs slow to drop on gearchange

Not to sure on all your questions but the temp should stay at 90 when the card warmed up so that sounds normal anyway.
 
Hi all.
i have a 1999 s3 8l and the revs seem slow to drop, is this normal? i have also noticed its got worse on fuel, getting about 22 mpg.
temp gets to 90 and stays there,

any ideas?

thanks.

Need a new clutch switch by the sounds of it, common problem on our cars, the switch is located down by the clutch pedal. The temp is fine.
 
Dual mass flywheel is heavy and revs don't drop fast... clutch switch can be tested in VCDS and will throw a fault code if faulty anyway so check that before replacing...
