GENERAL SERVICE BULLETIN Various Vehicles - Turbocharged Engines - Normal Turbocharger Sounds And Turbocharger Repairs	24-7023 14 March 2024
This bulletin supersedes 20-7092. Reason for update: revise the vehicle model years affected   Summary To assist with determining when turbocharger repairs are necessary, follow the Service Information.   Service Information Turbocharged engines may make a variety of sounds although the turbocharger is functioning properly. Some examples of normal turbocharger noises that do not indicate a durability concern include, but are not limited to: • Rattle noise at idle or during light load conditions • Whine noise that will track with engine speed • Whoosh noise on acceleration • Noise with wastegate actuation (creak, squawk) Axial or radial play in the turbo shaft is normal unless there is evidence of compressor wheel contact with the compressor housing. Do not compare turbocharger noises to other vehicles as part tolerances, engine calibrations, and other factors can cause sound characteristics to vary between otherwise similar vehicles. It is very rare for a turbo to have a problem without setting a DTC. Diagnostics should only be performed for turbocharger noise concerns if other symptoms are present in addition to the noise. The turbo should only be replaced if the pinpoint test for a DTC directs to replace the turbo or there is visible damage to the compressor wheel from compressor housing contact. Refer to applicable WSM and/or PC/ED Manual diagnostic routines when DTCs or additional symptoms are present.   © 2024 Ford Motor Company All rights reserved.
