VAG is price gouging on the Idle Stabilizer Valves (ISV) used on almost every VW Audi and Porsche that uses them. The aftermarket Mfg's in China are selling these generically for $35-$75.
Back in the day when VW, Porsche and Audi used to share part numbers the price jacking wasn't as bad. Audi has completely superseded the 037906457 from it's parts directory. It's notorious for using Audi specific part numbers on the same part. The difference can be 100's $$.
As long as a dual pin terminal ISV is purchased is will work on the G60. Right now there is a lot of cheap new old stock on these (NOS). Buy em up now G60 owners.
VAG has a stock replacement listed on the 80/90 Q for over $700. A, C, D & F are all the same except that C has its lateral port located on the top plane of the part instead of the bottom (as seen below).
