After you changed the thermostat did you properly bleed the cooling system of air?
I've known air locks to cause similar problems to the one you're experiencing.

TEMPERATURE GAUGE W126
Good day,,
My 1988 500SEL has a temp. reading problem.. the temperature sometimes climbs to 100 or 110 on the gauge, but using an electic temperature probe, it showed barely 80.
When i turn off the car and leave the ignition on, it suddenly drops around 5 deg. once started, it shows +5 again... a slight revving on neutral cuses the gauge to drop 5 to 8 degrees.. IS the temp sensor fried? or maybe i have overheatin problem...
Thx...
