The situation when Skoda Superb II Refusing to open your trunk is one of the most common problems faced by owners of this popular sedan and liftback. Mechanical wear, electronic failures or trivial battery discharge can paralyze access to the cargo compartment at the most inopportune moment.
You do not need to call a tow truck or contact a dealership immediately, as most problems are solved on their own. Understanding the principles of the electric lock and knowing the location of the emergency levers allow you to quickly return the car to working condition without unnecessary costs.
The main reasons for failure of the electric drive
Most often the problem lies in electrical circuitThe one in charge of the castle. If you press a button on the key or on the trunk lid, and in response you hear only a click or silence, then the signal does not reach the trunk. actuator Or he's not getting any food.
First check battery. Even if the engine starts normally, the voltage may not be enough to trigger the powerful motor of the trunk lock. In the winter season, this happens especially often due to a decrease in battery capacity.
Another common reason is fuse blown. In the electric circuit of the car for the operation of the trunk lock, a separate fuse is responsible, which can fail due to a short circuit or a voltage surge. Checking the fuse block should be the first step in diagnosis.
It is also worth paying attention to mechanical wear The castle itself. Over time, the gears inside the mechanism may be erased and the contacts oxidized, which will lead to a complete failure of the device, even if the electrician is working.
How to find and replace the luggage lock
To access the safety locks in Skoda Superb 2 You need to open the driver's door and remove the side plastic lining on the end of the dashboard. Inside you will find a block with lids of different colors, where each fuse is signed or numbered.
You need to find the fuse responsible for lock-keeping. This is usually a 10A or 15A item located in the area designated by the trunk symbol. Use a special plastic brace to remove the element.
If the fuse is burned out, it must be replaced with a new one with the same nominal value. Do not use "bugs" or elements with a large current of operation, as this can lead to fire wiring.
After the replacement, check the operation of the lock. If the problem remains, then the malfunction is deeper - perhaps it is in the wiring or the mechanism itself.
- Low battery
- Fuse burned out
- Broken mechanism
- The button doesn't work
Emergency trunk opening from the passenger compartment
If the electrician is completely out of order and the trunk is closed, there is a proven way to open it from the car interior. V Skoda Superb The second generation provides mechanical unlocking for such emergencies.
Remove the back seat by tilting the back forward. In the compartment between the cabin and the trunk you will see a hatch that needs to be opened. Inside is the cock-openerwhich mechanically removes the lock latch.
Pull this lever and the trunk lid will open. This will allow you to get inside and take out the necessary things. However, remember that the lock may need repair after that, as the mechanism may have jammed.
It is important to note that this method only works if the lock mechanism itself is not jammed mechanically. If the lever moves freely and the trunk does not open, the problem may be in the cable or traction.
βοΈ Actions in case of emergency opening
Diagnostics and replacement of the luggage lock
If the fuses are intact and the battery is charged, the problem is most likely to lie in the very lock-lock. It is a complex node that combines mechanics, electric motor and position sensors.
For diagnosis, it is necessary to remove the skin of the trunk lid. This will take time and care, as plastic clips can be fragile. Use a special spatula or flat screwdriver, putting elements around the perimeter.
After removing the skin, check it out. power connector castle. Oxidation of contacts or a fracture of wires in a tourniquet is a common problem. If the contacts are clean, call the multimeter voltage when you press the button.
If the voltage comes, but the motor does not turn, the lock must be replaced. Repairing it inside rarely makes sense, as the cost of a new mechanism is often comparable to the cost of repair.
What to do if you do not have access to the lock?
If you canβt remove the trunk skin due to a jammed mechanism, try to gently lift the trunk lid with a mounting blade through the seal to access the fasteners.
Checking of wiring and harness in hinges
One of the most insidious problems Skoda Superb 2 is a break of wires in the corrugated, connecting the body and the trunk lid. From constant openings and closings, the wires are broken, and the contact disappears.
You need to carefully inspect the rubber corrugated in the area of the hinges. Break it and check the integrity of each wire. Pay special attention to the wires going to the opening button and the lock sensor.
If you find a fracture, clean the ends of the wires and connect them with soldering or high-quality twisting with subsequent thermal shrinkage insulation. Simply gluing the tape is unreliable, as the vibration will again break the contact.
After restoring the wiring, be sure to fix the corrugated corrugated in a new position so that it does not stretch when the trunk is working. This will prolong the life of new compounds.
| Component | Symptoms of failure | Solution |
|---|---|---|
| fuse | Complete lack of response to the button | Replacement with a similar denomination |
| Battery | Dim lights, relay clicks | Recharging or replacing the battery |
| Lock mechanism | You hear the sound of the engine, but no movement. | Replacement of the entire lock node |
| Wiring (corrugated) | Periodic activation | Salting of broken wires |
β οΈ Attention: Before starting work on removing the trunk skin, be sure to turn off the battery's minus terminal to avoid short circuits when disconnecting the connectors.
Adjustment of the lock and the response part
Sometimes the trunk does not open because of a breakdown, but because of offsets The answer to the lock or the mechanism itself. If the cover is sagged, the latch may jam in the closed position.
Relax the bolts of the mounting of the response part and try to move it up or down a little. Close the trunk and check if it is too tight or too easy to close.
Also check the condition seal. If it is deformed or dried, it can create excessive resistance to prevent opening. Treat the seal with silicone lubricant.
Proper adjustment will ensure smooth operation of the mechanism and prolong the service life of all components of the locking system.
Before removing the lock, be sure to mark its current position relative to the body with a marker so that when installing a new mechanism, it does not take a long time to select the position.
Software failures and resetting settings
In rare cases, the problem can be programmatic. The comfort control unit can "hang" and not send commands to lock. In this case, a complete reset of electronics will help.
Turn off the battery for 15-20 minutes. This will allow all capacitors to discharge and control units to restart. After connecting the battery, check the operation of the lock.
If the reset does not help, it may be necessary. Diagnostics through OBDII. The scanner will show errors in the comfort unit, which may indicate a malfunction of the lock position sensors.
Sometimes it helps to flash the control unit, but this is a task for a specialized service, as it requires the availability of licensed software.
The most common reason for failure is not the breakage of the lock itself, but the breakage of wires in the trunk corrugated lid due to vibration.
β οΈ Attention: When resetting the battery settings, the clock, radio settings and the position of the glasses can be lost. Write them down before the power goes out.
Preventing trunk lock problems
To avoid a recurrence of the situation, regularly carry out preventive work. Clean the lock mechanism of dirt and dust using compressed air or a soft brush.
Make sure to lubricate the moving parts of the castle and the response part. silicone grease Or litol. Avoid using thick oils that can thicken in the cold.
Check the condition of the corrugated wiring at least once a year, especially if you live in a harsh climate. Early detection of cracks in the insulation will save you from serious problems.
Keep an eye on the battery and check its density and voltage regularly, especially before the onset of the winter season.
When to turn to professionals
If you have tried all methods of self-repair, and the trunk still does not open, it is better to contact specialists. Modern cars require sophisticated diagnostic equipment.
You will be given full service. computer diagnosticsCheck the power and ground circuits, and determine the exact malfunction of the mechanism. This will save you time and money on unnecessary parts purchases.
Also, specialists will be able to replace the lock with minimal risk of damage to the skin and paintwork, which is difficult to do at home without experience.
Do not delay repairs for long, as an open trunk can lead to theft of things or moisture getting inside the cabin.
β οΈ Attention: If you are planning to replace the lock yourself, buy an original part or a quality analogue in advance, as cheap Chinese copies often do not have the proper reliability.
FAQ: Frequently asked questions
