This part ( JY53-9B051- SO ) PURGE VALVE for a 2019 Vantage has a Mercedes Benz AMG equivalent. The Aston Martin one is on Back Order with no ETA?
A gentleman thats very familiar with the MB EPC helped me out immensely and given that the new vantage is a M177 engine, it's this equivalent Mercedes # 205-470-87-01-64. Item 1 in the picture below. It's also 1/2 the price.
