Search for coolant tube (replacement part)

Hello dear Motor Talk members, I need your help. At our Seat Alhambra (7593/AFJ) a coolant tube is rusted through and the car loses coolant liquid (currently not much, about 200ml/month). I wanted to renew the part and was already 2 (!) times in the Seat car house and they could not find the part in their system with these funny plans! First time it was said, come over with photos, then we can find the part already. The second time the photos did not help and even the boss was there, but unfortunately they could not identify the part. I was suggested to drive the car to the stage and start a search that would cost me at least a fifties. So to the competence and service of our Seat car dealership. Well, with a pipe piece, which probably does not cost even 20€… I don’t think I’m a single person on Earth who has the problem with the leaking coolant tube. Maybe someone already has so much 1. The Seat people broke at least to know where this coolant pipe comes from and where it goes. Only then can they (maybe) identify what part this is. 2. The best is point 1 and the name of the part. 3. Luxury would be to get the spare part number from the part. The coolant pipe (double version) is located around the drive shaft at the front right and is visible from below. You do not need to remove any panel. (see Fo.) tos) For the help I would be very grateful to you! P.S. I don’t know, but with the help of BMW catalogs I can always find every part for BMW, even small. At the Seat, however, the plans don’t seem to be exactly structured. Greetings
