Even if a Volkswagen’s strange noises sound similar, the cause can vary greatly depending on when the noise occurs
. Is it a rattle only while idling, a rattle at low speeds, or
a whistling sound at high speeds?
Narrowing down the noise by situation will help you identify the cause much faster.
In this article, we’ve categorized the most common VW noises that people report by situation. You can quickly find the cause and estimate repair costs by searching for the condition that best describes your symptoms,
such as “air conditioning on,” “when decelerating,” “the moment you turn the steering wheel,” or “when going over a bump .”
Abnormal noises are often an early sign, so
early detection can help prevent the problem from getting worse.

Noise while idling
The main noises that only come from the belts, plastic parts, and engine mounts when the car is stopped.
- Idling × Belt area × Rattling noise
- Idling × Interior/plastic parts × Vibration noise
- Idling × Engine mount × Rattling noise
Abnormal noise when starting
At the moment when the vehicle starts moving from a stop, it is likely to be the engine mount or the heat shield.
- When starting × Engine mount × Rattle noise
- Accelerator pedal × Engine/heat shield × Rattle noise (in many cases, this occurs immediately after starting)
Abnormal noise when driving at low speeds
This is the speed range where initial symptoms of suspension problems are most likely to appear.
- Low speed × suspension × creaking noise
- Low speed × suspension × tapping noise
- Low speed × suspension × rattling noise
- Low speed × suspension link × rattle noise
Abnormal noise when driving at high speed
Typical symptoms include wind noise and deterioration of hub bearings.
- High speed driving × Wind/Moor × Whistling noise
- High-speed driving × Interior trim/component resonance × Vibration noise
- High speed driving × Hub bearing × Rumbling noise
Abnormal noise when turning
Centrifugal force exposes “looseness in the suspension and deterioration of the bushings.”
Abnormal noise when driving straight
Snaking and initial rattle in the suspension.
Abnormal noise when stepping on the accelerator or accelerating
Be careful of the whining sound from the intake system and turbo.
- During acceleration × Turbo/intake system × Whinny sound
- Accelerator pedal press × turbo/fan × whirring sound
- Accelerator pedal press × Engine/heat shield × Rattle noise
Abnormal noise when decelerating or braking
Brake-related noises typically include squealing and grinding.
- When decelerating × Brake × Squeaking noise
- Braking × Pads/Rotors × Squeaking noise
- Braking × Pads/calipers × Grinding noise
- When decelerating × Brake/bearing × Grinding noise
Abnormal noise when air conditioner is on
Typical examples include problems with the blower motor and flaps.
- Rattling noise when turning on the air conditioner
- Hissing noise when air conditioner is on
- Air conditioner ON × Blower fan × Rumbling noise
- Air conditioner ON × Blower/flap × whistling noise
- Air conditioner ON × Blower motor × Rattling noise
- Air conditioner ON × Blower fan × flapping noise
Abnormal noise when operating the steering wheel
There is a lot of noise around the hydraulic pump, EPS and belts.
Abnormal noise when going over bumps
The cause is shock, bushing and interior resonance.
Abnormal noise after passing through a puddle
There is a lot of temporary slipping noise from wet belt brakes.
Sound after engine is stopped
Most of the time it’s the sound of catalyst heat shrinkage. This is usually normal.
- After engine stop × Catalyst/exhaust system × Clanging noise
- After engine is stopped × Heat shrinkage × Squeaking noise
General road noise while driving
The hissing and rumbling sounds are caused by the tires, road surface, and bearings.
The next step in abnormal noise diagnosis
If you are aware of any strange noises, reading the following in order will help you find the cause as quickly as possible.
- Summary by body part (this page)
- Details page for the relevant sound quality
- Individual symptom articles (e.g., slow speed x rattling / fast speed x whistling)

Details of defects by vehicle type
Even if the “way” of the malfunction is similar, “which model has the most common problems” differs slightly depending on the model.

Frequently Asked Questions (FAQ)
Q1. Even if the sound is the same, does the “situation” that causes it change the cause that much?
Yes. When it comes to abnormal noises, the clue is often “when it occurs” rather than “which part it is.” For example, the cause can vary greatly depending on the situation; for example, if the noise only occurs at high speeds, it could be the wind or bearings, while if it only occurs over bumps, it could be the shock or bushings.
Q2. If there is an abnormal noise but the car can still be driven, is it okay to leave it for a while?
Even if the car can still be driven, problems with the suspension, brakes, and turbo can deteriorate quickly, and if left unattended, repair costs can skyrocket. We recommend having it inspected early, especially if you hear a “grrr” or “whining” sound.
Q3. Are there any tips for finding the source of the noise yourself?
The key is to observe the situation as closely as possible. Diagnosis will be smoother if you note down reproducible situations such as “speed,” “accelerator on/off,” “presence or absence of bumps,” and “air conditioner on/off.”
Q4. Should I have my car inspected at a dealership or a specialist shop?
If you want genuine parts and peace of mind, a dealership is the best choice. If you want to keep costs down and have your car inspected by someone familiar with import cars, a VW specialist shop is the best choice. If the problem is minor, a general shop can handle it.
Q5. If an abnormal noise occurs in multiple situations, which items should I refer to? We
recommend that you first check the “situation that is easiest to reproduce,” and then check the surrounding items based on that possible cause. There are cases where multiple areas are deteriorated at the same time, so if it is difficult to determine the cause, it is best to have the vehicle inspected.
