Hi all.
new member here with a question for all you knowledgeable folks. I have a 2005 1.6 FSI Sport. Not had it long. The temperature gauge warning light is coming in then going off and back on again after a while, seems no regular intervals. Also the temp gauge shows bang steady on 90 degrees. Any thoughts as to what might be causing please. Thank you.
 
Never had an fsi but I know of no temp gauge warning light

There is a low water/coolant level light

Hi Mac.
The symbol is coming up on the DIS as a large red thermometer and also a warning noise. However I genuinely don't think the car is over heating as it happened yesterday after 30 seconds of the car being started up having been parked up outside for over 4 hours. Also the temp gauge never goes over 90 degrees. Thank you.
 
Must be the low level coolant warning, if you level is fine then its the integral sensor in the bottle. You can bridge the multiplug be that will obviously mean you will never get any warning regardless of coolant level
