Finding out noises from your auto regularly is never reassuring, so hearing noises on your Audi E-Tron suspensions when you go over a speed bump can be stressful. This sign may be a sign of a minor trouble as well as a warning of a much larger repair to come. Whatever the case, it is important to check the origin and take the necessary actions to solve the trouble, 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 causes 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 E-Tron
Check Audi E-Tron suspension
If you experience a suspension noise when you pass a speed bump on your Audi E-Tron, and it is characterized by a “clack” or cracking, it is highly plausible that your suspension block is the origin of it. Indeed, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small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 trouble 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 replacing them quickly or you may affect other parts and have to make more important repairs.
Check the cardan shaft
If you are here because you have searched for “Audi E-Tron 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 old and the dirt/dust accumulates inside them their action 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 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 E-Tron, don’t hesitate to refer to this article.
Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Audi E-Tron passes over a speed bumps, it is possible that the hinges or the stabilizer bar are responsible. Simply like the gimbals, the steering part is mobilized when you adjust direction. If this is the situation, the components that may have been affected by normal wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the origins of your noises, to verify it, put it under the vehicle and apply twists on each of its components to verify that there is no particular play on one of them, they are expected to resist you quite strongly over their entire travel. Please remember to take your vehicle to your technician or change them if they are involved.

Check the stabilizer bar
If, alternatively, you have a noise that is more like a squeak when you go over a speed bump with your Audi E-Tron, it is plausible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause abnormal friction which can generate this squeaking noise. Please remember to verify by going under your vehicle the condition of the paint on your bar which will indicate if there is friction. Second plausible explanation, it may be your stabilizer bar silentblocks that are dry and create noise, in which case take them off from the cradle and grease them, this should fix the trouble.
Check engine silentblocks
Finally, last point that we can verify together, it is the engine silentblocks, in fact, these silentblocks act as pads/shock absorbers between the engine and the cradle of the auto, a noticable fatigue of these will make 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 E-Tron. To change them go to your auto technician.
Other speed bump noise Audi E-Tron
If, even though all its assumptions, you still can’t locate the origin of the noise your Audi E-Tron makes when you pass a speed bump, we recommend you to refer to this content on a loud noise on Audi E-Tron or to visit your technician in order to carry an in-depth check on your Audi E-Tron and discover this trouble.
