“The car jumps forward when stopping → starting”,
“It shakes when decelerating”
, “The shock is big at D→R”,
“The creep is unstable and I’m afraid of starting”
This “jerky feeling in the low speed range” is one of the most common problems experienced by VW owners.
In particular, it is often said that the dry 7-speed DSG (DQ200) and wet 6-speed DSG (DQ250) are prone to low-speed shocks due to their structure.
But in reality,
it is difficult to isolate the cause because multiple elements such as accelerator, brake, engine, transmission, mount, suspension, and tires
are involved.
In this article, we organize the causes of shock when starting or stopping, and organize it as an “intermediate hub” that naturally leads to individual articles for each symptom.

The main cause of “jerking” when starting
(1) DSG Low Speed Control Disturbance (DQ200 / DQ250)
The most common is the disturbance of control in the low-speed region of the DSG.
In particular, the dry 7-speed is susceptible to heat and wear.
- It comes out with a jerk at the start
- The start of the step is delayed by one tempo and suddenly connects
- Shocked by D→R
It is easy to get symptoms.

(2) Clutch wear and oil pressure fluctuations
Clutch wear and hydraulic fluctuations in the mechatron directly affect the “connection” of
the start.
- Creep weakens
- The connection just before start is unstable
- Shock is strong only in the morning
If so, check it out.

(3) Disturbance of breathing and fuel conditioning on the engine side
If there is a faulty ignition system or sensor, the starting torque will not come out cleanly, and
the car will shake → “breathe suddenly”.

(4) Brake control and pad drag
If you jerk only between deceleration and stop,
it is often caused by the movement of the brake system.
- The pad drags lightly
- Stop just before stopping
- Jerking only on downhill
This is the symptom.

(5) Deterioration of engine mounts and mission mounts
When the mount deteriorates, the body cannot absorb the vibration of the engine and transmission, and
it is transmitted as a “front and rear shock”.
- Swaying back and forth when starting
- Shock occurs when the accelerator is turned on/off.
- Vibration is stronger than usual
If so, it is doubtful.

(6) Combination of misalignment + accelerator/brake shake
If you start or stop with a problem with a system that does not run straight,
you may feel a slight “rattling” shock.
- Jerking on bumps and ruts on the road surface
- Especially shaking just before stopping & immediately after starting
If so, check the undercarriage.
(7) Strong engine braking control (common in TDI)
The engine brakes unique to diesel cars are too effective,
and there are cases where they jerk when decelerating downhill.

(8) “Cold phenomena” that only appear in the morning
When the temperature is low, the ATF (DSG oil) and grease are hard and
difficult to control, so the shock is strong.
- I only get nervous in the morning
- It heals when the temperature rises
- Noticeable in winter
The main cause of “jerking” when decelerating
(1) Unstable movement of brake pads and calipers.
The jerking sensation during deceleration is often caused by brake problems,
such as sticking of the caliper and dragging of the pads.
(2) DSG downshift shock
In the D range, the shift shock of 2→1 and 3→2 is large, and
it is a case where it becomes a strong “click” just before stopping.

Driving availability and danger level
Almost all low-speed shocks are classified as “I can run, but I am uncomfortable and anxious”, but if left untreated,
it can progress to major problems.
- Worsening clutch wear
- Accelerated deterioration of bush mounts.
- Mechatronic hydraulic instability
- Heat generation due to brake dragging
- Increased shock of D→R → burden on the mission side
In particular, “D→R and bang” is not a symptom that can be left unattended.
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.

Points you can check for yourself
● Tire Pressure & Wear
It is very common as a cause of vibration and shaking.
●Brake smell
If there is dragging, it may smell burnt.
●Difference between cold and warm weather
Bad only in the morning → Suspicious mission oil viscosity and clutch control.
●Does the symptom change depending on the gear position?
The shock of the D→R is likely to be on the DSG side.
Approximate repair cost
- DSG Learning Value Reset: 5,000 to 15,000 yen
- Clutch adjustment and inspection: 10,000 to 30,000 yen
- Engine/Mission Mount Replacement: 20,000 to 60,000 yen
- Brake maintenance (cleaning to OH): 5,000 to 40,000 yen
- Pad and rotor replacement: 20,000 to 60,000 yen
If there are multiple causes, the costs may overlap.

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.
Trends by vehicle model and common breakdown cases among other owners are summarized on the following page.
Frequently Asked Questions (FAQs)
Q1. Is it okay to leave the symptoms of jerky at start?
A1. It is often not directly related to the inability to drive, but if clutch wear, mechatron instability, and mount deterioration progress, the repair cost will increase. In particular, strong shocks of D→R are recommended to be inspected as soon as possible.
Q2. Is the shock only in the morning a malfunction?
A2. When it is cold, DSG oil and grease are hard and the control is not calm, so symptoms are more likely to occur. However, there may be hidden deterioration of the clutch and mount, which worsens when it cools down, so it is recommended to inspect it if it becomes more frequent.
Q3. How can I tell if the jerky start is caused by the engine or the mission?
A3. If the accelerator is slow to respond or the rotation drops for a moment, it is likely to be on the engine side, and if there is a strong impact only at the moment of connection with D→R. Also, if you snap just before stopping, the brake system is also suspected.
Q4. Is there any improvement in the learning value reset?
A4. If it is a slight control disorder, there are cases where the starting connection can be improved by resetting the learning value of the DSG. However, if the root cause is clutch wear or mechanical malfunction, it is temporary even if it is improved.
Q5. How much should I pay for repairs?
A5. For light adjustments, it is about 5,000 to 15,000 yen, and if you need to replace parts such as clutches and mounts, it is about 20,000 to 60,000 yen. In many cases, there are multiple overlapping causes, so it is reliable to estimate after inspection.
