I have had this issue also and i've replaced the climate control with the help of my dealer. It was a long process but in the end, the dealer changed it at no cost. BUT!! Be careful because you will get no documentation that the part was replaced under guarantee, and if it will happen again the dealer will not change it! Mine was replaced in may 2019 and the line has reappeared again(2 weeks ago, when i started the car in the morning). Make sure that your dealer will give you some sort of documentation of the part covered by "Terms and conditions". Good luck in getting the problem resolved!
