Coolant loss in CFFB engines after EGR valve replacement

Good day.
As the title suggests, the engine is losing coolant. Approximately 5mm of condensation formed on the EGR cooler last night.
I've already located the spot, but I'm quite puzzled as to why it's leaking.
It's the hose located at position 16 (see attached image), on the AGR (Exhaust Gas Recirculation) side. There, you can clearly see an outlet.
Yesterday, I tightened the hose again and repositioned the clamp, but there was no improvement. I think I should replace the hose now; maybe I damaged it when I removed it.

The new AGR is a replacement part from Lemförder.

I would appreciate hearing their ideas and suggestions.


Best regards.

Since then, no further coolant has been lost.
It was probably due to the hose not being assembled quite correctly.

Thank you for the feedback!
