I want to replace the bleed nipples on my brakes.
For the FWD Audi TT with 314mm breaks, Audi provides the 1K0 615 273 A nipple on the VA. This is an M10x1 nipple with 29mm length. At the RA, the nipple 4D0 615 273 was chosen, which has since been replaced by the 1K0 615 273 C.
Both nipples at Audi cost € 7.20/unit in Germany.
Now I found quite complicated alternatives on the Internet that are significantly cheaper. However, the same nipples seem to be used for VA and RA ..
Can anyone confirm or disprove that this is the case and that the OEM 1K0 615 273 A and 1K0 615 273 C are ultimately the same valves?

Thanks for advice
Jochen

look for  447615273 or 1K0 615 273 A literally doesnt matter

M10x1 ,29/30+mm , costs like 2 bucks max, do not pay 8 euros for a bleeder valve.
