Best way to find out what you have, is to open the relay panel and have a look! chances are, it's the grey relay.
However, I would not worry too much about this. Internet forums are not a good predictor of how reliable a vehicle is, because people with problems ask questions while people without problems don't say much. This one gets questions asked a lot, because it's a problem that isn't in the "official" troubleshooting guide that the dealerships use, and it is an *intermittent* problem which are the worst kind to diagnose. This problem has been known to stump mechanics or get them barking up the wrong tree because they don't recognize the symptoms.
'96 Passat, with original-design black Relay 109, never acted up in 293,000 km, and I don't carry a spare. They don't always fail. Don't worry about it, just be aware of the symptoms.
