Hi Konrad..
Wrong Forum (x250 is what you have) but we'll be glad to help you here once 2 things occur..

1. Tell us what's Leaking with relevant pics.
2. Tell us what that juicy red droptop is!?😄

Nice sunglasses collection!

 

Sorry about being on the wrong side I'm not sure what the ex250 means my Jag has 34,000 miles on it and is leaking from the back side of the water pump under the intake manifold the red car is a CLK 350

 

In your profile, you show a 2010 XF which was model x250 (pre-2016 XF models).

X260 is 2016-present.

Are you a v8 engine?

Several TSB's exist for coolant leaking issues on both XF versions.
Your coolant tank looks indeed well below MIN.

In Kansas, I'm a youtube subscriber of The Wizard's Shop (Omega Auto Clinic) and would love to see him diagnose and fix your Jag..
