When turning back in the parking lot or moving forward from back, there may be a big shock with a “bang” at D→R (R→D).
It is a symptom that is often consulted at VW regardless of TSI/TDI, and multiple factors are involved, such as DSG control, engine mount, mission mount, and idle instability.
If it is mild, it is a habit of driving, but if left unattended, it may lead to clutch wear and mount damage.
In this article, we will organize the causes of shocks when switching in an easy-to-understand manner.

Common symptoms
- There is a shock when switching between D→R and R→D.
- Easy to jerky at low speeds
- The car body shakes when shifting even when stopped.
- High vibration at idle
- Creeps can suddenly become stronger
- I feel a lot of shock on slopes and backwards
There are four main causes.
- Clutch control disturbances in DSG (common in dry DQ200)
- Deterioration of engine and transmission mounts (lack of vibration absorption)
- Idling instability (rotation drop, compensation disturbance)
- Drive system rattle (drive shafts, bushings)
Cause (1) 😀 SG clutch control disturbance (most common)
When does it happen?
- Shakes greatly when starting→stopping→ turning back
- Sudden connection when switching between R→D
- Creep is inconsistent
Why do I have that symptom?
The dry 7-speed DSG (DQ200) is
a mission that adjusts the clutch connection method by “electric control”.
If this is off,
- The clutch engages abruptly when switching
- The control timing of the 1st gear/reverse gear is disturbed
- It is felt as shift shock
In particular, it is easy to lose learning values when driving mainly in the city and driving short distances.
If left unattended?
- The shock is even greater
- Faster clutch wear
- It can lead to the worst mechatronics problem.
Cause (2): Deterioration of engine and transmission mount (insufficient absorption of shaking)
When does it happen?
- The car body shakes at the same time as the shift lever is operated.
- Shock is also great when starting and stopping
- Idling bubbles
Why do I have that symptom?
The mount is a part that absorbs the vibration of the engine and transmission.
When deteriorated,
- The shaking is directly transmitted to the car body
- Even a small deviation in control can have a big impact
- The shock of D/R switching becomes stronger
In particular, if there is a lot of shaking during the D/R switching during a stop, the mount is suspicious.
If left unattended?
- Burden on other mounts
- Risk of damage on the mission side
- Stop/start shock worsens
Cause (3): Idling instability (drop in rotation speed and disturbance of compensation)
When does it happen?
- The moment you put it in D, the car body moves sharply.
- Idle rotation goes up and down
- Symptoms worsen with air conditioner on
Why do I have that symptom?
During the stop, the DSG, throttle and idle control are working at the same time.
Therefore, if the rotation is not stable…
- Correction does not keep up when switching between D→R (R→D)
- Torque comes out suddenly
- The car body shakes violently
Throttle dirt, airflow error, and auxiliary load are also greatly affected.
If left unattended?
- Developed into jerky driving
- Knocking feeling just before stopping
Cause (4): Drive system rattle (drive shaft, bush joint),
When does it happen?
- Every time you switch, you can hear a “thud” and “thud” sound.
- There is a rattle in the front and back when starting
- Often accompanied by extraneous noises at low speeds
Why do I have that symptom?
When the joints and bushings of the drive system deteriorate,
- Torque reversal when switching to D→R causes rattling
- The back and forth shaking is amplified
- Feel as a shock to the car body
In particular, the rattle on the lower arm bush and driveshaft inner side is likely to match the symptoms.
If left unattended?
- The rattle gets bigger
- Increased noise while driving
- Progression to drive system trouble
Points that can be checked in DIY
- D→R with high shaking → DSG control mount
- Bubbling even during outages → Mount deterioration
- The car body moves even though the pedal is not stepped on → Idle control
- “Clicking” sound when switching → Bush shaft system
- Creep too strong/too weak → DSG control
*It is difficult to judge on your own, so if you feel any abnormalities, we recommend that you have a diagnosis at the factory.
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.
Is it okay to drive? (Urgency)
- Light shock only: Drivable
- Big impact: medium (check early)
- Abnormal noise and large rattle: high (to the maintenance shop)
- DSG warning light on: Very high (no driving, recommended for towing)
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
There are a wide range of causes of large shocks in D→R (R→D), such as disturbed DSG control, mount deterioration, poor idle control, and drive system rattling.
If left unattended, it can lead to clutch wear and drive system problems, so if you feel a strong impact, it is safe to check it as soon as possible.
Even if the symptoms are similar, the causes vary from vehicle to vehicle.
Even if it is the same shock, the cause is different, such as the transmission mount and drivetrain.
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.
Trends by vehicle model and common breakdown cases among other owners are summarized on the following page.
Frequently Asked Questions (FAQs)
Q1. Is it normal to be lightly banged with D→R (R→D)?
A. If it shakes slightly, it is often a movement unique to DSG. However, if the impact is clearly strong or worse than before, DSG control disturbance or mount deterioration is suspected.
Q2. Will the shock improve if I reset the learning value of DSG?
A. If it is caused by a disalignment of control, it is often improved. However, if it is caused by clutch wear or mount deterioration, it will not improve, so diagnosis is necessary first.
Q3. Can I determine if the mount is deteriorating by myself?
A. It is difficult to make a complete judgment, but typical signs such as “large idling vibration during stopping” or “the car body shakes just by shifting” are typical signs.
Q4. Is it dangerous to drive like this?
A. It is possible to drive with a mild shock, but if there is a strong impact, abnormal noise, or rattle, the burden on the clutch and drive system will increase, and the risk of failure will increase. Early inspection is safe.
Q5. How much does it cost to repair?
A. There is a wide range depending on the content, but DSG training value reset is 5,000 to 15,000 yen, mount replacement is 20,000 to 50,000 yen, and bushing and shaft-related are about 10,000 to 50,000 yen.
