That is the opening temperature of the stat, not the maximum temperature that will pass through it.

Also, thermostat should be 88 on a 200 TDI - it uses a hotter stat than the 2.5 NA.
My new gauge must be very precise, I noticed it's actually reading 89 degrees, not 90. I gave her a good test run today, working the engine hard - much harder than I would in normal conditions. I could not get the needle about 89 degrees.

The lesson of this (for me anyway) is, it's not what's stamped on the thermostat, it's does it work properly. The stat that I took out was stamped 88 and was new.
I knew the rest of the system was good because my radiator is new (and I can feel it's working very well), the hoses are all in good order and the coolant is new and at the correct mix. The water pump was changed just before I got the engine and looked new to me when I changed the cam belt.
Although my stat was new as well, the signs indicated that's where the problem lay.
