VW vr6 engine - Knock sensor leaking coolant? - dipsomaniac

Struggling to find a coolant leak. It's a slow drip, when engine running it's faster. Looks like it may be coming from the knock sensor. Anyone else had this? Do I have to replace the sensor?

Unlikely. The knock sensor is actually a microphone bolted to the side of the engine block. It’s not in the coolant system.
