The moment you start from waiting for a traffic light, a strong vibration comes out——。
You will be anxious if you just step on the accelerator lightly but the car body shakes or the step becomes unstable.
At VW, multiple factors such as DSG clutch control, engine mount deterioration, ignition system weakness, and intake control disturbance often cause “strong vibration only when starting” due to the overlap of multiple factors.
If left unattended, it can lead to clutch wear, stalling, and worsening of low-speed jerking, so be careful.
In this article, we will explain in an easy-to-understand manner the causes of vibration during starting and how to identify it.

Common symptoms
- The body shakes only at the moment of starting.
- One tempo delay until the car comes forward
- Creep is weak and shakes greatly the moment you step on it.
- Strong vibration when starting on a slope
- There is also a shock when switching between D→R/R→D
- It often occurs in conjunction with low-speed jerks
There are four main causes.
- DSG clutch control disturbance (common in dry DQ200)
- Deterioration of engine and mission mounts
- Weakness of the ignition system and signs of misfire (plug coil)
- Torque disturbance due to dirt in the intake control (throttle airflow)
Cause (1) 😀 SG clutch control disturbance (most common)
When does it happen?
- Boom and vibration when starting
- Creep is weak and the start of stepping is jerky
- The moment the car comes out, it shakes with a “thud”
Why do I have that symptom?
The dry 7-speed DSG (DQ200) has
a structure that increases vibration during starting when the “control value” of the clutch connection is misaligned.
Specifically:
- The point of the half cra is misaligned
- Clutch engages abruptly when starting
- The holding of the first gear becomes unstable
In particular, if you only drive in traffic jams and short distances, the learning value is likely to go crazy.
If left unattended?
- Worsening of launch shock
- Progression of clutch wear
- Some cases lead to mechatronics disorders
Cause (2): Deterioration of engine and transmission mount (lack of vibration absorption)
When does it happen?
- Shakes back and forth a lot when starting
- Strong shock when switching between D/R
- Idling also bubbles
Why do I have that symptom?
When the mount (rubber part) weakens,
the movement of the engine and transmission is directly transmitted to the car body.
The torque change at the start causes a large shaking,
so the vibration is suddenly felt strongly.
If left unattended?
- Worsening of forward and backward shaking
- Increased burden on other mounts
- Further increased shock at launch
Cause (3): Weak ignition system or misfire (plug/coil)
When does it happen?
- Just the start shakes
- Slow-speed acceleration becomes a motif
- Boom every time you start at a traffic light
Why do I have that symptom?
If the ignition energy is weakened due to the deterioration of the plug coil,
it is easy to misfire at low rpm and low load.
When starting, the rotation is low and the load is large,
so even a slight misfire can be felt as a large vibration.
If left unattended?
- Check engine light on
- Poor acceleration and deterioration of fuel economy
- Risk of stalling due to sudden misfire
Cause (4): Disturbance of intake control (throttle and airflow dirt)
When does it happen?
- Torque at the beginning of the step comes out suddenly/does not come out
- Idling is not stable
- Starting is disrupted when the air conditioner is turned on
Why do I have that symptom?
If the throttle valve and MAF (air flow) are dirty,
the ECU cannot accurately compensate for the air intake volume, and the output at the start will be different.
- It doesn’t respond when you step on it
- After that
, the torque suddenly comes out→ which is felt as shaking and vibration.
If left unattended?
- Worsening breathing and stagnation
- Increased slow-speed jerking
So there are three options
In such a case, there are three realistic options for VW owners:
(1) First, a mechanic who is strong in diagnosis and estimation of
imported cars will identify the cause and propose the minimum necessary.
▶ Find a VW repair shop (buv.LABO)
(2) Foreign car specialty for appraisal
maintenance history and external parts plus assessment before high-cost repairs.
▶ Free appraisal with foreign car baton
(3) “New car at a fixed price” to avoid repair cost risk Relieve
yourself from breakdown stress with a monthly fee including vehicle inspection, tax, and maintenance.
One point
Even if you think it’s okay because you can run, you’re actually holding a bomb that you don’t know when it will explode.
The sooner you move, the less cost and damage you will have.
Points that can be checked in DIY
- Symptoms change when the air conditioner is turned on/off → Intake and control system
- It shakes back and forth only when starting → mount system
- Weak/abrupt creep → DSG control
- Unstable idling during stopping → Ignition and intake
- D/R switching to “bang” → mount or DSG control
*The final decision is made at the maintenance shop.
Is it okay to drive? (Urgency)
- Light vibration only: runnable
- It shakes loudly every time: medium (check early)
- Abnormal noise and shock: High (to the maintenance plant)
- Suspected misfire/warning light on: Very high (no driving)
When a driving problem occurs, it may be necessary to tow the truck depending on the situation.
In these cases, it may be covered by road assistance or riders of automobile insurance, so it is safe to lightly review the contents of your current contract.
If you may not have a proper understanding of the coverage, you can use a comparison service to check the coverage details and premiums of multiple companies at once. Since you can get a complete picture in a short time, many people use it for repairs and inspections.

Conclusion
Symptoms of strong vibration during starting are a point where multiple factors tend to overlap, such as DSG control disturbances, mount deterioration, ignition system weakness, and intake control dirt.
Especially immediately after starting, the load of the car changes greatly, and even the slightest discomfort is felt as a large shaking. Even if you have mild symptoms, you can rest assured that you will have an early inspection.
Even if the symptoms are similar, the causes vary from vehicle to vehicle.
Even if the vibration is the same, the causes are varied, such as the transmission, ignition system, mount, and air intake.
If you are unsure, it is safe to have it inspected at a maintenance shop without overdoing it.
Defect details by vehicle type
Although the “way of getting out” the defect is similar, “which model has many problems” is slightly different for each car model.

Frequently Asked Questions (FAQs)
Q1. Is it a major failure to vibrate only when starting?
A. When starting, the load is concentrated on the car, so small problems are likely to occur. The causes range from minor control misalignment to mount deterioration and misfire, and cannot be said to be a “major failure” in general. However, it is easy to get worse if left untreated, so we recommend early inspection.
Q2. Is it possible to fix it just by resetting the learning value of DSG?
A. In the DQ200, many of the starting shocks are due to deviations in the control values, so there are cases where the learning value reset can be improved. However, if clutch wear or mechatronics are progressing, the effect is weak and fundamental repairs may be required.
Q3. Can I determine if the engine mount is deteriorating?
A. It is difficult to judge based on shaking alone while driving, but symptoms such as a “bang” when switching to D/R and trembling even when stopped are typical signs of mount deterioration. Accurate judgment must be checked after lifting.
Q4. Is there a relationship between shaking when starting and jerking at low speeds?
A. There is a relationship. DSG control disturbances, intake dirt, and weak ignition systems tend to cause vibration and low-speed jerks at the same time, so if they occur simultaneously, they are often the same cause.
Q5. Is there a guideline for whether it is okay to run like this?
A. You can drive with a slight shaking, but you should avoid driving if there is a “big shaking every time”, “abnormal noise”, “stalling”, “warning light on”, etc. In particular, misfires and clutch system abnormalities deteriorate quickly, so early inspection is safe.
