Hi guys -- some confusion here when looking up part numbers for a purge valve.

When I look up a purge/regen valve on various (reliable) parts sites, I'm directed towards two separate part numbers; 000 470 22 93 and 000 470 87 93.

Some sites say that one is compatible but the other isn't, and others say they're both compatible. And FCP Euro says neither are compatible.

When I look on my car, the one I see is 000 470 22 93. But my question is, am I missing something here? Are these two distinctly different parts serving different functions? Or are the parts suppliers making a mistake saying one is compatible with my car and not the other?

I just want to clarify before I order anything.

AFAIK the difference is the plug look at the plug on yours and match it .

If I were you I'd get a used one on eBay just match the plug and put a small plastic inline fuel filter on it between the valve and canister. You can test the valve by blowing through it while connecting to 12V.

When I pulled off the vacuum hose I saw all those little pellets of carbon like you said. Can you point me towards an inline fuel filter that'll fit the application? When I look them up there are a million choices.

You can get it at any parts house. Clean out your Evap valve with a lot of electronic spray and test with 12V battery by blowing through it till it closes solid, The filter will fill up but no need to change, vacuum will pass through the pellets,
