my 88 sits at the lower thin white line after driving for 5 mins and stays there
so for this the first thing to do is clean the spade plug connectors on the water bridge
IF no change then swap out the T stat and rear stat seal and O ring then test it,
if no change then pull the pod and check the connections,
based on the miles and how the odometer is reading i would say its time for some pod cleaning and inspection
In this picture the sensor for the pod is to the right of the Tstat housing note the two different sized pins.
these pins get corroded and make bad contact clean them
NOTE the sensor thats on the left is for the engine computers and has 2 separate circuits, test it each pin to ground

First, thanks for your reply and suggestions.
A couple of questions. The space plug - would that be the plugs to the coolant temp sensor?
What (and where) is the rear stat seal exactly? Sorry I'll new with the 928 engine.

Thanks again!
The thermostat is located on the front of the engine. For it to work correctly the seating ring it works in conjunction with has to be in good condition. If this is not the case the cooling circuit flow will pass through the radiator before the engine is warmed up and in a cool climate can create a situation where it never warms up completely or takes ages to do so.
The needle position on your gauge suggests either an incorrect reading or a thermostat that is not working as it should.A motor that is working correctly should have a water temperature coming out of the engine of about 95C give or take a little.
The engine's brains rely on the temp2 sensor resistance to determine the actual engine temperature and is critical to successful operation- it has two channels- one for the LH and one for the EZK units. What you see on the dash panel comes from another sensor on the water bridge but that has no impact on how the engine is managed..

Is this temp gauge reading correct?
