This is a used OEM Audi power steering reservoir, part number 8E0422373B, also known as the power steering tank. It supersedes the earlier 8E0422371B and 8E0422371. This reservoir stores and supplies fluid to the power steering pump, and a common failure is a cracked body or leaking cap seal, which leads to low fluid levels and whining from the pump.
