What do you mean by history? It's the latest revised valve block hence the Q3 sticker, it was bought new 2 years ago. Asking $600 plus shipping, it retails for $1900 new at the dealer. If your car drops you need a valve block.Hi, What is the history on it? How much are you asking? Mine does not leak but drops after sitting for an hour and is the reason I want to replace. Thanks for any info.
