Hi all

Noticed the other day that there was a little puddle under my car. After having a little look around under the car, I found these drops on the bottom of the front sub frame (Pics attached).

The car had a leak when I bought it off of the previous owner so took it to BMW for them to diagnose it and they said it was the radiator so it was replaced back in Jan. Since then I've had to top up the coolant occasionally which raised some suspicions but there was no evidence of a leak anywhere.

Does anyone have any idea of what could be causing this?

Any insight/help is much appreciated.
