The one I got from the dealers last year was machined crooked where it mounts to the car and had a chunk missing out of it. Got a refund, no biggie.
That one you've got will probably be ok, although it looks like a standard Bosch cap so you're getting ripped off either way. The Volvo ones should be shinier than that as they were/are extra lacquered.
There'a an original one on
ebay US right now. RAREEEEEE
