Initial publication
Customer states:
 There are rattling noises at 1000 – 2000 rpm from the underbody. They are more audible in the rear of the
vehicle.
Workshop findings:
 The rattling noise from the fuel lines can be duplicated.
 The fuel supply line (between fuel pump and connector in the area of the inner sill) is detached at the fuel tank.
Technical Background
The TT fuel supply lines can vibrate against the fuel tank in certain cases. This phenomenon occurs when the two
fuel lines begin to resonate between 1000-2000 engine rpm and rattle against one another or the tank.
Production Solution
