Leaking oil cooler on S2

[nightSpirit]

After a fun day at Abingdon yesterday, the car has decided that it doesn't want so much oil and deposited it out the offside rear cooler. I've almost got it out of the car but before I do so I wanted to check that I have the stock item (car is running tfsi engine) and if there's an uprated core I can get from say mocal? This cooler is really small and looks OEM. Common fault also?

Ok, I've taken the cooler off now. It's not stock (silly me), it's a Mocal 13 row 115mm -6 standard duty (I think) core with the aeroquip push type fittings.

I'm thinking it's rare for a cooler core to fail so it's more likely the connectors but the oil traces were in the left side of the matrix...wierd.
