Ticking Fuel Injectors?
I have a ticking noise under the hood. And from my listening around it sounds like its coming from that area were the fuel injectors are, but its hard to tell if its that or coming from the valve cover. Its a tick tick tick when its idle but speeds up when i give it gas. It stays one volumn level. Any ideas before i take it in?
Its an 04 5AT with 79k miles on it

I have been having the same problem. A not so loud ticking noise at idle and if you give it some gas it ticks a little faster paralleling the RPM but does not get louder it stays at one level. I do have aftermarket injectors though, I have APS injectors if I recall correctly. Would it be the same or noisier than stock injectors?
Glad I found this post.

If it is the injectors, i think i can tackel the job myself, of replacing them as all id have to do is take off the plenum, witch i have done. Id just like to make sure that it is, so im not spending money on something if its not it. Ill need to find out how much oem injectors are. Then should i replace are of them?
When i take my car in for the 78k service ill ask them diagonis that noise and see what they say. But not have them do anything.

The dampeners are the disc looking things attached to the fuel rails.

Unable to duplicate- said that possib;y what I *heard* was maybe the result of some detonation from a bit of poor qualiy gas or partially clogged injector and nothing to worry about.... they did a fuel system treatment (pressureized cleaner) and tested the gas- all seems well. But, I'll monitor it- if it acts up again, most likly it's just noisy injectors/ on their way out.

Just got back from the dealer. Its not the fuel injector, the noise is coming from inside the valve cover in the back, passanger. Didnt get fix but have an idea now.
