AMUS says Audi's problems are all hydraulics related. So it's like a Newey car from the early 2000s
Those responsible have so far been relatively tight-lipped when asked about the cause of the problems. According to information from auto motor und sport, it was mainly defects and leaks in the vicinity of the hydraulics that caused the high failure rate. With the new cars, the system has become much more complicated. For example, the front wing adjustment is now also connected to the hydraulics.
