Only up to 3000rpm is the pre-injection. The mapping for it stops almost dead at about 2900rpm iirc.
Just put a load of sound deadening material under the engine cover and wrap it around the injectors a bit. I've never done it but I'm 95% certain that is what you are hearing.
The pulleys also go but you really do hear them all the time. I bought a new OEM one and within 6 months could hear the tell-tale tickety tick at idle parked in the garage!
