I feel there is a design flaw in the electrical front seats in the B5 chassis A4/S4 (1996-2001 A4 and 2000-2002 S4). I owned a 1998 Audi A4 and currently own a 2001 Audi S4. Both have been plagued with a front seat that rocks back and forth under acceleration and braking, the extent of which worsened dramatically over time. The problem was never fixed on my A4 with the Audi dealers I consulted telling me that the movement was "within" specs. Is it within spec to rock almost an inch? it seems like a serious safety concern since the greatest stresses would be during some kind of emergency braking manuever. Eventually my S4 had the seat-frame replaced as the movement got to where it apparently was "out of spec". I asked for what the guideline was and was not provided with a quantitative answer. I know many others with this same issue that have not had any satisfactory resolution, and I have little confidence that the issue will not rear it's head with my "fixed" seat, probably within the next year or two. This has not been an issue with other cars I have been in made my Honda, BMW, Mercedes and more so the "all seats do this" argument presented by Audi does not seem to hold much water. If the seat bracket and frame are wearing out of the manufacturer's tolerances within months of ownership, it seems like a faulty design which creates a possible and probable safety hazard for many people on the road. I urge you to work with Audi to improve their seat/design/parts for existing owners before any serious injuries to owners or passengers occur. Thank you. - andrew chang.
