S4 CREC Engine Coolant / Waterpump

[roberto.]

Hi, looking for some help or opinions from those with S4s and have had water pumps or thermostats changed. I've got a very slow coolant leak currently, which nothing shows up during a pressure test on the system. I've currently got the charger off the car and it's still not obvious where it's coming from. The most apparent area looks to be from the water pump as the pulley is especially wet and has the most visible coolant marks.

PCV looks dry, and I'm got no issues with oil consumption.

Pictures below show the current look of the engine bay looking a bit sad.

Not easy if you can’t see the leak.
Sounds like the pump but it could be wet from removing the charger.
Good luck

Waterpump off and it's evident it was totally cabbaged. Bearing was shot and it's obviously been leaking a bit for a while.

New pump on, gaskets, thermostat and rings. So good news. Reference for anyone searching in the future.
