ŠKODA Yeti trunk button: secrets of control and repair

ŠKODA Yeti is a compact crossover that is valued for its practicality and reliability, but even its owners sometimes encounter problems related to trunk release button. Either it stops responding to pressure, or the trunk opens spontaneously, or the button simply “falls through” without any result. In this article we will analyze all the nuances: from the location of the button to diagnosing faults and eliminating them.

Feature Yeti — a unique luggage compartment control system, which depends on the year of manufacture and configuration. For example, in models before 2014, the button is often integrated into the driver’s door lock, and in restyled versions (2014–2017) it was moved under the trunk handle. We will tell you how to find the button in your modification, what signals indicate its malfunction and what to do if the trunk stops opening.

Where is the trunk button located? ŠKODA Yeti?

The location of the button depends on the generation and equipment of the car. B Yeti the first generation (2009–2013) and the restyled version (2014–2017) have key differences:

• 🔑 Before 2014: The trunk release button is most often built into driver door lock (turn the key to the left or press the key fob button). Additionally, there may be a mechanical latch under the rear bumper.
• 🚗 Facelift 2014–2017: the button has been moved under trunk handle (on the right under the gas tank flap) or on key remote control (button with an image of an open trunk).
• 🔧 Inside: in some configurations the button is duplicated on dashboard (next to the headlight dimmer) or on driver's armrest.

If you can't find the button, check operating instructions for your modification. For example, in Yeti Outdoor (2011–2017) often installed an additional button in the trunk - it is located on the inside of the lid, next to the lock.

How to open the trunk if the button does not work?

If The trunk button stopped responding, don't panic - there are several alternative ways:

1. Mechanical method: There is a hidden latch under the rear bumper (usually on the right). Pull it up and the trunk will open. In some models, the latch is hidden under a plastic plug.
2. Through the salon: Fold down the rear seats (the lever next to the headrest) and access the trunk lock from the inside. Pull the cable or press the lock lever.
3. Keychain: If the button on the key fob works, use it. If not, check the battery in the key (type CR2032).
4. Emergency cable: some modifications have an emergency cable (orange) under the rear seat. Pull it and the trunk will unlock.

If none of the methods work, the problem may be electric lock or fuse. Check the fuse F35 (10A) in the block under the steering wheel - it is responsible for the central locking circuit.

What to do if the trunk opens but does not close?

If the trunk opens but does not lock in the closed position, check:

- Microswitch in the lock (may be dirty or broken).

- Drive cable — it could come off or tear.

- Trunk lid hinges - if they sag, the lock will not fit into the groove.

Temporary solution: close the trunk using a rope, securing it to the hooks in the luggage compartment.

Common problems with the trunk button

Trunk button on ŠKODA Yeti may fail for several reasons. Here are the most common:

Malfunction	Reason	Solution
The button does not respond to pressing	Contact oxidation, wire breakage, microswitch malfunction	Disassemble the button, clean the contacts, check the integrity of the wiring
The trunk opens spontaneously	Short circuit in the circuit, control unit malfunction	Checking fuses, ECU diagnostics, replacing damaged wires
The button “fails” with no effect	Worn spring or broken button mechanism	Replacing a button or its mechanism (article no. 5E0 827 051 C)
The trunk can only be opened with the key	Malfunction of the electric drive or central locking unit	Drive diagnostics, relay testing J393

Important: if the trunk opens spontaneously, do not ignore the problem - this may lead to battery drain or property theft. Most often to blame comfort block (J393), which is responsible for controlling the central locking. It is better to entrust its diagnosis to specialists with equipment for reading errors (for example, VCDS).

How to disassemble and repair the trunk button?

If you decide to repair the button yourself, follow these instructions. Before starting work disconnect the battery (by removing the negative terminal) to avoid short circuit.

Step 1. Removing the button:

• 🔧 Remove the plastic trim of the trunk handle (it is secured with latches or screws Torx T20).
• 🔌 Disconnect the button's power connector (gently pull the latch).
• 🛠️ Unscrew the screws securing the button (usually 2 pieces) and remove it.

Step 2. Diagnostics and repair:

• 🔍 Check contacts for oxidation (clean with alcohol or WD-40).
• 📶 Test the circuit between the button contacts with a multimeter (when pressed, the resistance should drop to 0 Ohm).
• 🔄 If the button is mechanically broken, replace it with a new one (original article number - 5E0 827 051 C, analogues - 1K0 827 051).

Step 3. Reassembly:

• 🔩 Install a new button or reassemble the old one in reverse order.
• 🔌 Connect the connector and check the operation of the button before installing the cover.
• 🔧 Secure the cover and check the tightness (water should not enter the mechanism).

Problems with the electric trunk lock

If the button is working, but the trunk does not open, the problem may lie in electric lock. On ŠKODA Yeti it is located inside the trunk lid and consists of a motor, gearbox and cable.

Symptoms of a drive failure:

• 🔊 Clicks when you press the button, but the trunk does not open.
• 🔄 The lock works partially (the lid opens slightly, but does not lock).
• 🔋 The drive only works when pressed again.

For diagnostics:

1. Remove the trunk lid trim (it is attached to plastic clips).
2. Find the drive (black block with a connector) and check its operation when the button is pressed.
3. If the motor does not rotate, check the voltage at the connector (should be 12V when pressed).

If the drive is faulty, it can be replaced (original article number - 5E0 827 851, analogue - 1K0 827 851). The cost of a new drive is from 3,000 to 5,000 rubles. An alternative is repair (cleaning gears, replacing motor brushes).

What to do if the trunk does not close?

If the trunk ŠKODA Yeti opened but does not close, the reasons may be as follows:

• 🔐 The lock does not lock: Check to see if any debris or ice has gotten into the mechanism (especially in winter). Lubricate the lock WD-40.
• 🔗 The cable has slipped: In the lock drive, the cable could fall out of the groove. Disassemble the mechanism and install it in place.
• 🔋 Microswitch faulty: if the lock does not “feel” the closed position, replace the switch (part number 1K0 905 847).
• 🚪 The hinges sank: Over time, the hinges of the trunk lid sag and the lock does not fit into the groove. Adjust them or replace the bushings.

Temporary solution: close the trunk using a rope, securing it to the hooks in the luggage compartment. But don’t put off repairs—long-term use with a faulty lock can lead to damage to the hinges or electronics.

⚠️ Attention: If the trunk does not close due to a broken cable, do not try to close it by force - this may break the plastic lock mechanism. It is better to temporarily secure the lid with a rope and contact service.

Prevention of malfunctions of the trunk button and lock
