MightyMo1993 Posted March 29, 2022 Share Posted March 29, 2022 Hi guys, I hope you can help. I have a CDAA 1.8 TFSI engine in my 2011 A3 Sline black edition. I have a coolant leak out of one of my coolant hoses, I've replaced the coolant flange that it attaches to (06J 121 132D) but the hoses that connect from it to the heater core are what's leaking. And I can't find the correct part numbers anywhere!! I've tried ordering some hoses before but they were the wrong ones!!! If anyone can point me in the way of a diagram of the system for my engine or help with part nos would be massively appreciated!!! Quote Link to comment Share on other sites More sharing options...
