So the Octavia recently had it's first 30k Km service, and the brake fluid was changed.

But now when I park up, and turn off the engine, there is a funny buzzing noise coming from the brake pedal. If I keep my foot pressed on the brake pedal I can feel the "buzz" and vibration, which sort of sounds like something deflating :wonder:

Anyone have an idea what this could be?

Does this happen on anyone else's car? If you key off and keep your foot pressed on the brake pedal, do you hear a "dzzzzz" sound, and feel the brake pedal move further towards the floor?

OK I took this in to the dealer, and they said it is normal.

Just thought I would post that in case anyone else has the same experience.
