Discovering noises from your car regularly is never reassuring, so listening noises on your Audi Tt suspensions when you pass a speed bump can be stressing. This sign 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 source and take the necessary actions to eliminate the issue, it is with this objective in mind that we wanted to write this article 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 Tt
Check Audi Tt suspension
If you experience a suspension noise when you pass a speed bump on your Audi Tt, and it is categorized by a “clack” or cracking, it is highly plausible 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 In fact, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small bumps that compress the suspensions. To verify if this is the issue that worries 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 swapping them quickly or you may ruin other parts and have to make more important maintenance.
Check the cardan shaft
If you are here because you have researched for “Audi Tt 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 amasses inside them their working is degraded and it is possible to experience a sound when they are in torsion. To verify 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 circumstances you should consider replacing it or them. If you have the feeling that this noise is more like a a loud noise on Audi Tt, don’t hesitate to refer to this article.
Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Audi Tt passes over a speed bumps, it is imaginable that the hinges or the stabilizer bar are responsible. Just like the gimbals, the steering part is mobilized when you adjust direction. If this is the case, the parts 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 causes of your noises, to verify it, place it under the automobile and apply twists on each of its elements to verify that there is no special play on one of them, they are supposed to endure you quite strongly over their entire travel. Remember to take your vehicle to your mechanic or change 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 pass a speed bump with your Audi Tt, it is plausible that it is the stabilizer bar itself that is concerned. In fact, abnormal/pronounced wear of the latter can cause unusual friction which can cause this squeaking noise. Remember to verify by going 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 remove them from the cradle and grease them, this should solve the issue.
Check engine silentblocks
Finally, last case that we can verify together, it is the engine silentblocks, in fact, these silentblocks operate as pads/shock absorbers between the engine and the cradle of the car, a noticable fatigue of these will generate a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise occurs when you pass a speed bumps or any holes with your Audi Tt. To replace them go to your auto mechanic.
Other speed bump noise Audi Tt
If, even though all its assumptions, you still can’t uncover the origin of the noise your Audi Tt makes when you pass a speed bump, we recommend you to consult this content on a loud noise on Audi Tt or to visit your mechanic in order to carry an in-depth check on your Audi Tt and find this issue.
