Coolant Message in Display Upon Startup
 

Good Morning Everyone:

I’ve recently encountered a error message in my display on my 1.8T 2003 Audi A4. Upon start up approximately 20% of the time, I receive a beep sound and the Coolant message flashes. This will momentarily stay anywhere from 1-5 minutes, but it always goes away. My heat works fine (as far as I can tell) and my temp gauge acts normal as it gradually climbs to the 12:00 position and then stays.

As a small side note, this issue doesn’t appear to be weather-related. There have been days in the past couple weeks that the temp was about 10, while I just got the message this morning and the temp was 45.

Anyone have any input on what the issue is here?

Have you checked the coolant level when it beeps at you and compared it to when the car doesn't beep? Could be low coolant, air in the system, a bad level sender, etc.

That was it man - it was just a little low. Low enough to where when it was really cold, it through the code temporarily before the car had a chance to warm up.

Thanks for the tip!
