Not sure exactly what it was out of because it was included with the vehicle I bought, the person who sold it to me seemed to think that the injection pump in the car was bad, but after getting the car running, that doesn't seem to be the case. It is definitely for OM617 engines. It looks to be in good/working condition, which was what was promised to me when I purchased the car, but I cannot guarantee anything since I've never installed/tested it.
I'm not entirely sure if I want to sell just yet, I'm more just gauging interest and what I can get for it. If there's sufficient interest/offers, I will post pictures etc
I'll do my best to answer any questions.
