Yours is a 87C, and your thermostat needs replacement because is not closing.

VW dsahboard coolant temp indicatro says 90C if real temp from coolant temp sensor says 70 to 102C, so if yours says 80 fuel sensor is getting maybe 65C.
MAybe you need also a replacement for the coolant temps sensor Sensor temp. refrigerante para VOLKSWAGEN Golf III 1.9 TD 75cv a bajo precio

Ask your repair shop to change thermostat and coolant sensor and put VW G12 coolant (G12+ it is a good option). IT's organic, not water with chemical that reacts when you mix different cheap coolants.
I'm using a 12 per 5L like this:
IADA Productos
Technical data:
Safety data:
It should be liquid from -37C to 145C.

Excellent- many thanks! I shall investigate the thermostat, and getting it replaced. Certainly does sound like its running cold.

A new thermostat appears to be under 10, so not a massive investment. Coolant is simple enough to get too.
