Finding out noises from your car frequently is never reassuring, so hearing noises on your Audi A2 suspensions when you go over a speed bump can be worrying. This symptom may be a sign of a insignificant issue as well as a warning of a much larger repair to come. Whatever the case, it is important to check the cause and take the necessary actions to eliminate the issue, it is with this intention in mind that we wanted to write this document to help you see more clearly. We will first see the possible reasons 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 A2
Check Audi A2 suspension
If you experience a suspension noise when you pass a speed bump on your Audi A2, and it is categorized by a “clack” or cracking, it is highly plausible that your suspension block is the cause of it. Indeed, it may be the suspension cups, which, when they are dead, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small bumps that compress the suspensions. To examine if this is the issue that worries you, take a dented road and focus on the noise coming from your front axle as you circulate over holes. If it is indeed the cups, think of changing them as soon as possible or you may ruin other parts and have to make more important repairs.
Check the cardan shaft
If you are here because you have looked for for “Audi A2 suspension noise” and the suspension is not the cause of your problem, it may be that the cardan shaft is responsible. Indeed, when the cardan bellows get out of date and the dirt/dust accumulates inside them their action is degraded and it is possible to experience a noise when they are in torsion. To examine 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 make a turn at low speed. If it cracks in these two situations you should consider replacing it or them. If you have the feeling that this noise is more like a a loud noise on Audi A2, don’t hesitate to read this document.
Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Audi A2 passes over a speed bumps, it is imaginable that the hinges or the stabilizer bar are responsible. Simply like the gimbals, the steering part is mobilized when you change direction. If this is your situation, the components that may have been broken 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 examine it, position it under the automobile and apply twists on each of its elements to examine that there is no particular play on one of them, they are expected to resist you quite strongly over their entire travel. Remember to take your vehicle to your mechanic or swap them if they are involved.

Check the stabilizer bar
If, on the other hand, you have a noise that is more like a squeak when you go over a speed bump with your Audi A2, it is plausible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause uncommon friction which can generate this squeaking noise. Bear in mind to examine by passing under your automobile the condition of the paint on your bar which will show if there is friction. Second plausible explanation, it may be your stabilizer bar silentblocks that are dried out and cause noise, in which case take them out from the cradle and grease them, this should resolve the issue.
Check engine silentblocks
Finally, last case that we can examine together, it is the engine silentblocks, in fact, these silentblocks process as pads/shock absorbers between the engine and the cradle of the car, a evident weakness of these will make a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise shows up when you pass a speed bumps or any holes with your Audi A2. To replace them go to your auto technician.
Other speed bump noise Audi A2
If, despite all its assumptions, you still can’t find the source of the noise your Audi A2 makes when you pass a speed bump, we advise you to consult this content on a loud noise on Audi A2 or to visit your mechanic in order to carry an in-depth check on your Audi A2 and identify this issue.
