Brake Pedal Clicking Noise

[dougler2]

I thought I would start another click thread as I believe this is separate from the turn signal one. On my B9 first thing in the morning when I start out once I get up to right around 40 km/h for the first time there is a distinct buzz/click type sound that comes from the brake pedal area. It makes the sound twice back to back, then its gone. seems to consistently happen as I pass through 40 km/h the first time of the day, then I never hear it again. It's almost like abs priming or something. Are others experiencing the same? I'll try to remember to take a video next time I'm in it.

My B9 does the exact same thing the first time the car hits 25-26 mph after start up. It does the double click and then never does it again for that session. I wondered what it was too (first Audi).

Mine does the same at 25mph as well. Its the ABS system. I'm familiar with it ,my 04 Titan does this also and I've been driving it for the last 12 years

Does anyone happen to know what is actually happening within the ABS system when those clicks happen? Is it activating?

Also have this, sounds like a circuit breaker/relay switching on/off
