993 Fluttering Idle

[LGR993]

Hey All,
New car for me. 1995 993 Carrera. When coming down off high RPMs the idle is super bouncy at idle. I'm told that this is due to either a) dirty ISV Valve or b) a worn one.

Having cleaned it twice, I'm going with the latter. However, the Bosch part 0-280-140-543 seems to no longer exist. Pelican doesn't have it and no one else in the states does either. Is it true that Porsche is no longer allowing them to manufacture it to push people to the far more expensive OEM?

The OEM part 993-606-160-00. $771 at Pelican, but they have to order it.

If anyone knows more about this or where you can still get the Bosch part please LMK. Thanks.
