Mystery Coolant Leak in BMW E46 - Seeking Advice

Hi all, I own a BMW E46 with a N46b20 2.0 litre engine and I've been experiencing a coolant leak. I need to top it up every 3-4 days, and it seems to be coming from the back of the engine, but I can't pinpoint the exact source. Does anyone have tips or ideas on where it might be leaking from? Any advice would be greatly appreciated!

Summary of the thread

A suggested cause is a potential leak from the heater core hoses or their connections, which are common problem areas in this model. Checking these components for signs of leakage or damage is recommended as a first step in diagnosing and resolving the issue.
