This coolant pipe eliminates a known failure point from VW Golf/Jetta/Passat/EOS and Audi TT/A3 with BPY-code 2.0T FSI engine. Found in the upper radiator hose, the crack-prone original part number is 1K0121087H and it's best to remove + replace it.
Our piece is machined from aircraft grade 6061-T651 aluminum vs injection molded plastic. It is professionally TIG welded, and then pressure checked . This one will permanently stop the nonsense caused by the cheap original plastic coolant fitting.
