The pulley on my 2015 Golf failed last week, and I had oil (grease from inside the pulley, actually) all over in exactly the same location as your photo shows. Also, the protective end cap came off the end of the alternator pulley - I found it down below, sitting on the top of the plastic pan under the engine. With that cap missing, it is possible to look inside the center of the pulley and see the splines on the bolt holding the pulley on the end of the alternator. The bad news: VW does not sell the pulley as a replacement part, you have to replace the entire alternator, which is a $1,000+ repair.
Cons: pulley failed, grease leak, cap detached, expensive replacement
Vehicle:
Volkswagen Golf
