Can someone out there do me a favor??

So we all know the High Pressure Fuel Pump's ticking sound can be fairly loud in these cars. Today I noticed that if I take the throttle up to about 1,000 rpm the ticking becomes very rapid. I have a feeling this is normal, but if anyone else out there knows for sure, or if you'd be kind enough to pop your hood, and listen to your engine I'd appreciate it.

Here is a video. You can really hear what I'm talking about the 2nd time I raise the revs from idle:

I cannot hear the ticking speeding up in that video. However does it speed up a bit when you rev the rpms up and then take your foot off immediately? That's what mine does.

Can you further explain what you hear? To me I hear something but am not sure if its background noise or just crappy ipad speakers

Thanks for taking a look at the video.

Not exactly. If I hold the rpms at a steady 1,000 rpm, the rapid ticking will stay constant. Again, it may be normal, but I just don't remember it standing out from before. I try my best to be "in tune" with my car, but I don't remember if it has always done this or not.

Yeah it can be difficult to hear in the video, but I feel the 2nd time I raise the rpms up, it seems pretty apparent. Probably harder if you don't know exactly what your looking for. Its right from the 14 to 16 second mark.

See my above post...14 - 16 second mark is the best time you can hear it. The other times are more difficult. Its the ticking noise you hear at idle, but at a much faster pace.

If you were to give it a try on your own car...you'd hear it for sure...assuming it is normal lol.

Now that I grabbed my good pair of headphones I do hear what your talking about. But I can't say I have ever heard it on mine. If my car wasn't all covered up I would check and see for you. Maybe someone else who goes to their car everyday can chime in and confirm that it's normal or not

I appreciate that. I don't expect anyone to go out of their way to check of course, but it would be great to know, if anything, just to feel better about things lol.
