hi guys ent been around for awhile just bought a 2000 agu 1.8t but the temp gauge only moves up a tiny bit like one little line.the temp sensor looks like its been replaced if im looking at the right thing?? on the right side of the engine on a water pipe green thing lol. I have fault code 16500 engine coolant temp / circuit-range/performance problemany help would be great
If it goes up one bar it should keep going in theory, check the wiring first, I have seen a few of these with temperamental wiring, I have had to plug / unplug some 4 or 5 times before they work
