Coolant bleeder valve leak
In my case the problem was leakage under the bottom of the Coolant bleeder valve (part no. 999 707 371 40). At the bottom of the Coolant bleeder valve with the transition to the Coolant reservoir is an O-ring that in my case was outdated and did cause the leak. If it leaks, the coolant will run down the drain on the right rear. On advice I replaced the entire Coolant bleeder valve including O-rings.
