Coolant level low!!! 2013 s8

[Grkwolf20]

Hello guys,
I was wondering if anyone could give me some possible reasons for this. Bought the car and coolant was low, and I took it to the dealer and the performed full coolant flush and pressure tested it everything was good. car sat in my garage for couple of days and when I tried to started there was the light again which right after driving for less than a minute went off. I checked the level and it was less than minimum which makes me believe something consumes the coolant. No traces of leaks. Any ideas?

Cylinders are dry? Any difficulties starting the car after its been sitting?

Did you take bottom engine cover to inspect for leaks?

Cylinders dry?? Do you mean traces of fluid on the side? And yes no leaks at all. Is there a known issue with turbos burning coolant on these cars? I mean it's bizarre but today looked like the bottle was empty and when car warmed up it was below min , two days prior the level was a little below min at cold temp. And I want to believe it was an air pocket after flush and it worked it way down. I just dropped it to the dealer and they told me that they couldn't see anything but they will leave it under pressure all night and look in the am for any leaks. I am just not very familiar with common issues with the s8's I just hope isn't the turbos or head gasket with car at 55k miles.

There is a known issue with coolant leaks at the turbo in the early 4.0s but it's pretty easy to spot and there are several threads on this topic on this site and others, pull the decorative engine cover and a flashlight and look down in the valley at the turbos. There are several lines that go to the turbos and they can leak from there.
