Clicking noise when brake pedal is pressed

Hello,

This morning, as I got in my 04 A4 GTO to go to work, I pressed down on the brake pedal and heard a distinct clicking noise from the transmission area. If I let off the brake pedal and pressed it again, the clicking noise would occur at about the same braking pressure everytime. Once I started the car and put it in drive the clicking noise never came back.

I'm guessing the clicking noise is the part that keeps you from shifting from park without the brake pedal depressed disengaging. It was cold this morning (around 40 degrees, cold for Florida anyways), so that may have made the clicking noise louder than usual and I just happened to notice it.

Has anyone else heard this noise? I'm not to worried about it, but I did want to check to see if it is normal.

I think you are right, I was told it was some little gizmo going bad, but was nothing to get worried over. My 06 does it only ever great once in awhile, but I still have warranty

If you are in park and hit the brake petal and hear the click it is the safety switch and completely normal. If you hear a click in "D" there is another issue.

It's the a4 interlock that allows the shifter to disengage park. Mine does it occassionally and then stops. I'm curious as to this as well.

I did find some old threads that were about the same clicking sound. It sounds like it is fairly normal in cold weather.

This is NORMAL. There is a solenoid in the shifter that actuates when you step on the brake pedal. ALL newer model cars have this feature. There is nothing wrong with your shit. However, if you would like, I would be glad to charge you about $788 dollars to "fix" this for you.

it's the solenoid for the park safety feature. it releases the solenoid after brake pressure is applied so you can shift out of park

Owning a GM vehicle, I guess we all should accept the "this is normal" line and go on our way without wondering why GM couldn't have put more effort into various parts of the car in the first place. I've never heard any other modern automatic transmission car make that noise before, so obviously it is possible to engineer a solenoid that stays quiet.

Lucky for them, I seem to be drawn towards their wonderfully engineered LSX engines.

If you get into ANY modern car with an automatic transmission, close the door...turn the key on....and be smurfing quiet for 2 seconds....THEN step on the brake, you WILL hear this solenoid work. I don't care what kinda car it is, you will hear it. The reason most people do not hear it is because they get in their cars like cattle on the run, slam the door and waller the seats and turn the ignition on and start the engine all at one time....all the noise of this action usually drowns out the miniscule noise this solenoid makes. Try it for yourself, you'll see.

My first SEARCH victory!

I bought my GTO in June, and it's my DD.

Haven't heard this noise 'til 2 days ago. Got the car washed, got in it to leave, and CLICK. It was freaking me out.

However...

If I listen closer, not only does the shifter click...

If I press the button on my shifter, I can hear an even smaller 'click' come from the cluster. Is THIS normal???
