Hi,
Has anyone else experienced same issue, my temp gauge in my Golf Mk4 2.0 8v only goes to the first line (even when vehicle has been running for a while), it will ONLY sit at 90" if the engine is running and not been driven.
Here's a pic (I had just driven for about 20 minutes and it only moved to the first line)
I have had the temp sensor replaced, the only other thing I can think of is the thermostat?

Thanks in advance,
