159 low temperature?

The last few days ive noticed the car not reaching its usual 90 temp on the guage. It seems to fluctuate on the low end

Its noticeable that if i put my foot down, i can physcially see the needle rise. But its not hitting 90.

Any ideas?

when temp goes up after flooring it a bit and you take your foot off to coast does it drop again pretty quickly after, if so thermostat stuck open is first thought.

IMO Thermostat. Have you got multiscan so you can stick it on your laptop to read engine temp thru ECU. To confirm its running cool. If M says temp 89 c then obviously your sensor or guauge or wiring in knackered.
