help needed please 90 degree bleed nipple

[daviesbike]

Hi Guys

Yesterday my cooling system through a wobbly..

The 90 degree bend with a bleed nibble on for the cooling snapped. And Audi say the part dose not exist at all... dispite this part being on every D3 I've had W12 and other wise...

I can only discribed it as the plastic joint that goes through the engine firewall and joins on to the matrix piping side of things ...

Has any one ever had to replace this ..

A. I don't know what it's called to search for it ..
B. Audi say it doesn't exist ... as do tps and other motor factors ..

Any help would be greatly appreciated
