Air spring fault finding Customer Statement: -The front and/or rear suspension appears to have dropped Technical Background: -Bentley vehicles which are applicable to this TPI are fitted with air springs as part of the suspension system. Should air leak from the air spring dampers, this will cause the suspension to drop. However, the dropping of the suspension does not necessarily mean that the air spring is faulty. -The Measure section of this TPI describes how and where to check for air leaks on the front and rear air springs, the air supply unit, pipes, valve unit and air reservoirs. This includes potential air leak points on the air spring dampers and also the locations of an air leak that can be repaired without the need to replace an air spring damper. |
