## NHTSA's summary

Air spring fault finding. Customer statement / workshop findings: The front and/or rear suspension appears to have dropped. Technical background: The list of Bentley vehicles below are fitted with air springs as part of the suspension system. Should air leak from the air springs, this will cause the suspension to drop. However, the dropping of the suspension does not necessarily mean that the air spring is faulty. TheMeasure section of this TPI describes how and where to check for air leaks on the front and rear air springs, the air pump compressor, pipes, valve unit and air reservoirs. This includes potential air leak points on the air springs and also the locations of an air leak that can be repaired without the need to replace an air spring. These checks should be carried out in conjunction with the Elsapro procedure Air suspension: To check with the use of the special tool Air suspension leak tester VAS 751 001 shown in the image below as item \( 1\). Refer to Elsapro, Repair Group 43, Air suspension To check.
