Hey all,

Have a 2016 1.8tsi ibiza cupra. It has a slow coolant leak, maybe 50 ml over 4 weeks. Water pump has been replaced, no sign of a head gasket issue (oil/coolant contamination, white goo in oil, power issues or smoke). Is there anything I should look out for? Cant see any coolant on anything. I'm thinking a small hole in a pipe somewhere or maybe the thermostat housing?

Any help or experience in this would be greatly appreciated. Have some kroon oil sp13 to keep it topped up (meets the VW 774 j spec), but want it sorted.

Cheers
