Hello, after I have been made aware by PN that a survey is wanted, which should bring a little clarity, how many % of the A3 drivers really have problems with their chassis, I have taken this up. In the survey multiple answers are possible. In this thread only to be coordinated, you can add comments as a thread, which contain more detailed information. For example: Type (Ambition, Ambiente, Attraction, S-Line) Month/year construction Engine Generally satisfied with the FW: (Yes, No) Vehicle hops: (Yes, No) Vehicle gets in vertical resonance (hopped): (Yes, No) If resonance, then at approx. km/h: (Speed) Driving comfort overall: (Unacceptable, Go so, Moderately satisfied, Satisfied, Very satisfied) Everything should be kept as short as possible so that this thread only serves as information. You can still discuss this in the thread: My A3 hops. If you want to change or supplement the survey, please PN to me. Greetings Jürgen
