[V8] Coolant Expansion Tank

[Buchholz, Steven]

... my data point is for the correct V8 part purchased from an Audi dealer ... I think I paid ~$60 for it.  I had much better luck with the 5kCSQ expansion tanks myself ... but from my POV they are built the same way, so I would not expect to see any difference ...
