E400 brake pedal noise
Maybe a stupid question, but I was trying to track down a rattle (surprise surprise) and had the radio and hvac off.
I noticed that I could hear the brake booster pump and bleed off when applying/releasing the brake pedal. It’s definitely not a prolonged “woosh” or anything but it IS noticeable. I checked my VW and Audi and you can hear the same noise when the car is off but not on.
Can anyone confirm if you can hear the same noise? Trying to figure if this is normal before going to track it down.
Thanks!
