Listening noises from your automobile often is never comforting, so discovering noises on your Audi A1 suspensions when you go over a speed bump can be disturbing. This symptom may be a sign of a insignificant trouble as well as a warning of a much larger repair to come. Whatever the case, it is necessary to check the source and take the necessary actions to solve the trouble, it is with this objective in mind that we wanted to write this content to help you see more clearly. We will first see the possible explanations for a crack when the speed bump passes, then, what can be the cause of a squeaking noise when a speed bump is being passed and finally what to do if you have another noise when a speed bump is passed.
Suspension cracking noise Audi A1
Check Audi A1 suspension
If you notice a suspension noise when you pass a speed bump on your Audi A1, and it is characterized by a “clack” or cracking, it is highly possible that your suspension block is the cause of it. In fact, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its job during small bumps that compress the suspensions. To check if this is the trouble that concerns you, take a dented road and pay attention to the noise coming from your front axle as you drive over holes. If it is indeed the cups, think of replacing them fairly quickly or you may affect other parts and have to make more important maintenance.
Check the cardan shaft
If you are here because you have researched for “Audi A1 suspension noise” and the suspension is not the cause of your problem, it may be that the cardan shaft is responsible. In fact, when the cardan bellows get old and the dirt/dust builds up inside them their operation is deteriorated and it is possible to experience a sound when they are in torsion. To check this, you can try both types of torsion, first vertical with suspension compressions on the speed bump passages, and horizontal when you are going to turn at low speed. If it cracks in these two conditions you should consider changing it or them. If you have the feeling that this noise is more like a a loud noise on Audi A1, don’t hesitate to check out this content.
Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Audi A1 passes over a speed bumps, it is imaginable that the hinges or the stabilizer bar are responsible. Exactly like the gimbals, the steering part is mobilized when you modify direction. If this is the case, the components that may have been damaged by regular wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the origins of your noises, to check it, position it under the car and apply twists on each of its elements to check that there is no particular play on one of them, they are meant to resist you quite strongly over their entire travel. Remember to take your Audi A1 to your mechanic or replace them if they are involved.

Check the stabilizer bar
If, however, you have a noise that is more like a squeak when you go over a speed bump with your Audi A1, it is possible that it is the stabilizer bar itself that is concerned. In fact, abnormal/pronounced wear of the latter can cause uncommon friction which can create this squeaking noise. Remember to check by passing under your car the condition of the paint on your bar which will show if there is friction. Second possible explanation, it may be your stabilizer bar silentblocks that are dry and bring on noise, in which case take them out from the cradle and grease them, this should solve the trouble.
Check engine silentblocks
Finally, last case that we can check together, it is the engine silentblocks, actually, these silentblocks work as pads/shock absorbers between the engine and the cradle of the automobile, a obvious weakness of these will create a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise appears when you pass a speed bumps or any holes with your Audi A1. To change them go to your auto technician.
Other speed bump noise Audi A1
If, despite all its assumptions, you still can’t find the origin of the noise your Audi A1 makes when you pass a speed bump, we recommend you to consult this content on a loud noise on Audi A1 or to visit your mechanic in order to carry an in-depth check on your Audi A1 and identify this trouble.
