So on my Passat 1.9 TD with AAZ engine, over about 2,300 rpm there's a clacking noise coming from the region of the injection pump. The car drives fine although it's a little rougher than I'd like at idle. I'm not sure if the injection timing is right but I've been adjusting it slightly to see if it helps, and it doesn't. I mean, it helps with the idle but the noise is still exactly the same regardless.

Is my pump on its way out?
