2019 Q7 - The coolant warning sounded as well as the screen display to shut off engine. The engine was shut off and when restarted none of the warnings were present, plus successive driving and restarts showed and no signs of a problem, plus the temp gauge showed totally normal. Any ideas? Thanks

 

Had the same issue a couple of times this month. Check the coolant level it might be low. Add some coolant. The light should go off. Check for any leaks as well.

 

My Audi Q7 3.0 TDI from 2015 with 272hp, it is loosing coolant water. I have looked and checked all the water pipes and found nothing. In one week time I have to fill up 1 litre coolant water weekly. Can please anyone help with an advice what to do or how to fix this issue with the coolant water? Please help me. Thanks
