Autodata helps one garage get to the bottom of why their customer’s Audi A5 was making a metallic noise from the front wheels when manoeuvring and parking.
The problem
“A customer’s 2017 Audi A5 Sportback is in for a service and the owner has reported a metallic noise from the front wheels whilst manoeuvring or parking. We have heard the metallic noise and we suspected it was originating from the front brake pads due to them being very low. After replacing the front brake pads and road testing the car the metallic noise is still apparent. Are you aware of other Audi owners who may have reported this type of metallic noise before?”
What does Autodata recommend?
Yes, this fault has been reported to us by A5 Sportback owners with late model year vehicles. The metallic noise is due to movement between the front wheel bearing housing and the front hub carrier. Remove the front wheel bearing housing from the hub carrier, but do not remove the wheel hub from the front wheel bearing. Thoroughly clean all corrosion from the front wheel bearing housing and apply a light coating of Optimolpaste, available from Audi parts department, to the mating surfaces of the front wheel bearing housing and hub carrier. Refit the front wheel bearing housing to the hub carrier. Repeat the procedure for the opposite side and road test the vehicle to ensure the noise has been eliminated.
