I also got my -04 cap like this from a respected indy. The tag on the bag looks genuine, so hopefully it's ok. The missing part number could be an annoyance down the road...

I have the same. No part number on the cap. Weird. My indy strongly favors using OEM whenever possible. Maybe this is new VW takeover stuff...
suppliers are not being directed to follow part numbering protocol strictly. But that meshy thing on one and not the other seems weirder.

OK - so another dumb question. If you replace just the cap. Say I order one, it shows up, I take the old cap off, put the new one on (i just checked and mine ends in 01 so it must be an original), am I going to have a problem with air getting into the system by just changing the cap???

I'd just make sure that the engine is cold, say after it's sat over night you'll be fine. Unless you've been having to add coolant recently which might have introduced air into the system.

Since this car is new to you I have a general rule when it comes to anything coolant system related:

Don't guess. Have the professional check everything out. You can't kid around with this part of the car.

The cap is cheap but plays a critical role. In my opinion, the latest cap should be part of the PPI, as well as replacing the coolant tank. Coolant should be flushed at some interval, people debate how often, but once you decide to do this you have to make sure it's been done right by previous owners.
