The moment you release the brake from waiting at a traffic light, the car comes forward with a “thud”, or on the contrary, it does not move at all and moves one tempo behind……
There are many consultations about “creep not stable” at VW, especially in dry 7-speed DSG (DQ200) This is a common symptom.

It can be a precursor to a major failure, or it can also be caused by a simple control misalignment or dirt in the intake system.

In this article, we will summarize the causes and how to distinguish when creeps appear or do not appear in an easy-to-understand manner.

Common symptoms

  • The car does not start moving even when the brake is released.
  • The timing of movement varies from day to day
  • Weak ability to move forward
  • On the other hand, there are times when you suddenly step forward with a “goof”
  • Stop-start jerks
  • The start of movement is especially unstable on uphill slopes
  • It tends to get worse in the cold

There are four main causes.

  • DSG clutch control misalignment and wear (most common)
  • Idle instability due to dirt in the intake system and sensor deterioration
  • Weak ignition system does not produce low-speed torque
  • Unable to absorb shaking due to deterioration of the engine/transmission mount

Cause (1) 😀 SG clutch control misalignment and wear (most important point)

Common symptoms

  • Creep is weak
  • The time before it starts to move is varied
  • Shocked by the connection between D→R and R→D

Why does it happen?

VW’s dry 7-speed DSG (DQ200) is an “artificial creep” method that “artificially creates creep” while adjusting the
position of the half-clutch electronically.

Therefore,

  • Clutch wear
  • Temperature Compensation Deviation
  • Bias in learning values
  • Mechatronics operating errors.

If there is, the creep will not be stable.

Especially as wear progresses,

  • “Connection position” is misaligned
  • Half a crab time is longer
  • → Weakening/delaying the start of movement

This phenomenon is more likely to occur.

If left unattended?

  • Worsening jerk at start
  • Increased shock
  • It can eventually lead to problems that do not fit in gear

Cause (2): Idle is not stable due to dirt on the throttle and airflow

Symptoms

  • The rotation drops only the moment you release the brake.
  • Weak/slow start of movement
  • Torque at the start of the run varies

Why?

Creep uses “idle torque”,
so if the idle is unstable, the creep will also be unstable.

Especially

  • Dirt on the throttle valve
  • Reduced power of the airflow sensor

If there is, the torque put in by the ECU changes every time,

  • Coming out or not coming out
  • One day I come forward strongly

It leads to unstable movement.

Cause (3): Weak ignition system (plug coil)

Symptoms

  • Creep is weak only in the morning
  • There is a slight vibration
  • Difficult to produce low-speed torque

Why?

If the combustion is not stable, the idle torque will also be unstable.
If the ignition coil or plug is deteriorating,

  • The idol misfires slightly
  • No torque when cold
    → Weak creep

In a typical flow.

Cause (4): Deterioration of engine and mission mount

Symptoms

  • Large shaking at the start
  • Creep shock increases
  • A feeling of jerk remains.

Why?

The mount is responsible for absorbing vibrations.
When this place deteriorates,

  • Clutch connection directly to the car body
  • “Booming” and “booming” shaking occurred

Apart from weak or strong creep, it is a type of symptom that increases “unnatural shaking”.

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.

▶ Check monthly on Sompo

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

  • Warms up and heals → DSG temperature compensation or intake compensation problems
  • Weak only on hills → Clutch wear is suspected
  • It shakes only in the morning → Ignition system or mounting possibility
  • D→R switching with large shock → DSG control misalignment or mounting
  • Even more unstable with the air conditioner on → High possibility of the intake system

*Since it is difficult to judge, we recommend a factory inspection.

Is it okay to drive? (Urgency)

  • There are days when it doesn’t work completely: danger (DSG harbinger of serious trouble)
  • There are days when creep is weak and days when it is strong: medium (DSG control misalignment)
  • Large shaking or shock: medium (mounted or intake or DSG)
  • Heals after warming up: Low to medium (easy to improve with early inspection)

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

Creep is created by the idle torque of the engine and the clutch control of the DSG, so it will be unstable if there is a fault on both the engine side and the mission side.

If the strength of the movement varies depending on the day, or if it is weak only in the morning, an early inspection is recommended. In some cases, it appears as a precursor to a major breakdown, so be careful.

Even if the symptoms are similar, the causes vary from vehicle to vehicle.
Even if it is the same “creep instability”, there are various causes such as DSG control, air intake system, ignition system, mount, etc.
If you are unsure, do not overdo it and have it inspected at a maintenance shop.

Defect details by vehicle type

Frequently Asked Questions (FAQs)

Q1. Is it a breakdown that creep has weak and strong days?

It may be a harbinger of a breakdown. The start of movement may change depending on the temperature and conditions of the day, such as deviation in the learning value of the DSG clutch, wear, and dirt in the intake system. If there are days when you don’t move completely, it’s a red flag.

Q2. Is it normal for creeps to be weak only in winter mornings?

It is not uncommon for it to become slightly weaker, but if there are symptoms such as delayed movement or large shock, problems with the ignition system, intake system, and clutch control may be hidden. If it continues regardless of the season, we recommend checking it.

Q3. If you can run if you step on the accelerator even though there is no creep, is it okay to drive?

At least you can run, but it is not safe. If the creep does not appear, it is a state where the position of the half-cra is not grasped, and the DSG problem may be progressing. We recommend early diagnosis.

Q4. Is it possible to just clean the throttle or replace the airflo?

It is. In particular, creep defects with unstable idling are often improved by dirt in the intake system. However, if the cause is on the DSG side, it will not improve.

Q5. Is the jerking in D→R or R→D related to the creep problem?

Closely related. If the clutch actuation position is misaligned or the mount deteriorates, the front and rear connections will be disturbed, making it easy to creep instability and shock at the same time. Both are important signs of DSG inspection.
