Welcome to the new look VWWatercooled

After much work and little sleep there is a new version of the forums running on more powerful and recent hardware as well as an upgraded software platform.

Things are mostly the same, but some things are a little different. We will be learning together, so please post questions (and answers if you've worked things out) in the help thread.

The new forum software is an upgraded version of what came before, it's mostly the same but also a little different. Hopefully easier to use and more stable than before. We are learning together here, so please be patient. If you have questions, please post them here. If you have worked something out and can provide an answer,

  • Help! - Loud buzzing noise during ACC auto braking

    Hi all - we just completed a 3k drive up to Queensland over Xmas in my 162 with largely no issues. What we did start noticing was when the adaptive cruise control applies the brakes a kind of buzzing (or almost tweeting) sound is quite audible, particularly at low speeds. Some forums say this can be a characteristic of the ACC hydraulic braking but seems odd that it wasn’t audible in the other Tiguan I’ve driven and has only popped up after a few thousand km’s.

    Any tips? Go back to the dealer or perfectly normal?
    Thanks!

    Get it checked out. Could just be a loose-ish mount for whatever controller/regulator applies the brakes electronically, when it’s not human-foot powered. My Mazda made a slight noise from under the dash area when it actuated the brakes via radar cruise. Not to the level you’re describing though.
