Modern VAG vehicles are equipped with sophisticated electronic systems that control every movement. When a yellow or red light light lights up on the dashboard, the owner becomes concerned about the safety and cost of repairs. Mistake. 00907 on cars Skoda It is often the subject of disputes between car owners and craftsmen, as it indicates a serious malfunction in the brake system.
This fault code is not an accidental sensor failure, but indicates problems with the control of the hydraulic unit or electromagnetic valves. Ignoring such a signal can lead to loss of anti-lock system functions, which is critical in difficult weather conditions. It is important to understand that the car with such an error retains basic braking capabilities, but loses stabilization systems.
The essence of the malfunction and decoding the code
Code 00907 In diagnostic scanners, it is often abbreviated as “ABS/ESP valve control circuit” or “Electromagnetic valve failure 1 (N110)”. Depending on the version of the control unit firmware and the car model, the wording may differ slightly, but the essence remains unchanged - the electronic module cannot correctly control one of the hydraulic valves.
The Anti-lock Braking System (ABS) uses a set of solenoids to redistribute brake pressure between the wheels during emergency braking. If the control unit detects a circuit break, short circuit or resistance deviation in the control circuit, it records the error. 00907 And it shuts down the system. This is a protective mechanism that prevents uncontrolled brake operation.
For owners Skoda Octavia, Skoda Superb or Skoda Karoq This means that when you try to reset the error, the system will return it again after several ignition cycles, if the physical cause is not eliminated. Diagnosis requires a careful approach to the electric part of the car.
The main reasons for the failure
The most common cause of 00907 error is physical damage to the wiring leading to the ABS block. Vibration, temperature changes and aggressive road surface environment over time destroy the insulation of the wires, which leads to a break or a closure on the mass.
The second common problem lies in the hydraulic control unit itself. Electromagnetic valves inside the module can stick or burn due to dirt entering the brake fluid or natural wear of the coils. In such cases, it is not just a mistake reset, but a complex repair or replacement of the unit.
Sometimes the problem arises due to the incorrect operation of the electronics control unit (ABS controller). This happens less often, but it is impossible to exclude the option of failure of power chips or control drivers. This is especially true for cars with a mileage of more than 150 thousand kilometers.
- 🔌 Breaking or closing the wires in the tourniquet going to the ABS module.
- ⚙️ Failure of electromagnetic valve N110 inside the hydraulic unit.
- 💧 Getting moisture into connectors or oxidation of contacts on the shoe.
- 🔋 Voltage surges in the onboard network, which damaged the electronics of the unit.
Diagnostics of the electrical circuit
The first step in fixing the 00907 error is to thoroughly check the electrical circuit. You need to remove the connector from the ABS unit and visually inspect the contacts for oxidation, dirt or traces of overheating. Even the slightest disruption of contact can cause a valve control error.
Use a multimeter to measure resistance on the contacts responsible for the N110 valve. The resistance must be within the range specified by the manufacturer (usually 2 to 6 ohms). If the instrument shows “infinity” (break) or zero (closing), the problem is precisely in the wiring or the valve itself.
Don’t forget to check the integrity of the wires along the entire length of the tourniquet. Sometimes the break occurs inside the isolation, and visually it is imperceptible. Call the circuit from the block connector to the connector coming from the engine control unit or safety unit.
☑️ Circuit Checklist
⚠️ Warning: Do not try to start the engine or drive a car with a faulty ABS system unless you are sure of the serviceability of the base brakes. Error 00907 can cause the wheels to lock during emergency braking.
Repair of hydraulic module and valves
If the electrical circuit is in good working order but the error persists, the problem is most likely within the hydraulic module itself. Electromagnetic valves in ABS VAG units are often corroded by moisture ingress through seals or by the use of poor-quality brake fluid.
Repairing such a unit requires specialized equipment and skills. In some cases, only the valve coil can be replaced if the design allows it to be dismantled. However, most often a complete replacement of the hydraulic unit or its professional repair with the replacement of all solenoids is required.
It is important to note that replacing an ABS block often requires adaptation and coding in a service. Simply putting a new iron unit is not enough, it must be paired with the immobilizer and other vehicle systems through a diagnostic interface.
Can I drive with a faulty valve?
Technically, the car will continue to brake, as the hydraulics work mechanically. However, the ABS and ESP systems will be completely disabled. This means that when braking on a slippery road, the wheels will be blocked, and the car can go into a skid without the possibility of stabilization.
- 🛠️ Replacement of the N110 electromagnetic valve with a similar new one.
- 🧹 Complete cleaning of contacts and contact groups from oxides.
- 🔄 Replacement of the entire ABS module with subsequent adaptation.
Procedure for error resetting and adaptation
After eliminating the physical cause of the malfunction, it is necessary to remove the error code from the memory of the control unit. This can be done with a professional diagnostic scanner, such as VAS-PC, VCDS or multi-brand level scanners Launch and Autel.
Go to the section "Block 03 - Brake Electronics" (03-Brake Electronics). Select the function “Erase Error Codes” (Clear DTCs). If the cause is eliminated, the error will not return after restarting the engine and a small mileage.
In some cases, especially after the unit or sensors have been replaced, an adaptation procedure is required. This may include calibrating the steering angle sensor, adjusting the brake pressure and testing the valves. Missing this stage can cause the system to work incorrectly.
Pay attention to the sequence of actions in the diagnostic equipment menu. An incorrect reset can result in a system lock. Always make sure that all system parameters are normal before resetting.

- Wiring problem
- Hydraulic unit
- No problem
Table of common ABS errors on Skoda
To better navigate the problems of the braking system, it is useful to know what errors occur most often. The 00907 error is not the only one that can occur in the ABS system. Below is a table with the main fault codes and their brief characteristics.
| Error code | Description | Probable Cause | Difficulty of repair |
|---|---|---|---|
| 00907 | Valve control circuit 1 (N110) | Wiring break or burnt valve | Average |
| 00908 | Valve control circuit 2 (N111) | Damage to the harness or valve coil | Average |
| 00287 | Wheel speed sensor (right rear) | Dirt, wire break or sensor failure | Low |
| 01276 | ABS pump does not work | The pump motor or safety lock has burned | High |
⚠️ Note: If the error returns instantly after replacing the sensor or wiring, check the ABS unit for internal short circuits. The problem is often with the controller, not with the external elements.
Prevention and operating tips
To avoid recurrence of error 00907, it is necessary to regularly maintain the braking system. Use only the quality brake fluid recommended by the manufacturer and change it every two years or 40,000 kilometers.
When washing a car, avoid direct contact of powerful water jets in the connectors of the ABS unit, usually located in the underhood space or in the area of wheel arches. Moisture that gets into contact is the main enemy of electronics.
Keep an eye on the safety locks. If the fuse responsible for the ABS system has burned out, do not replace it with a more powerful one. This can cause the wiring or the control unit itself to burn.
Before the winter season, be sure to check the condition of the ABS connectors and clean them of oxides. Low temperatures and reagents accelerate the corrosion of the contacts, which can lead to the occurrence of 00907 error at the most inopportune time.
If you are planning a long-distance trip, make sure that all security systems are in good working order. Error 00907 can come on suddenly and you won’t be able to find a service quickly on the way.
Regular replacement of brake fluid and protection of connectors from moisture are the best ways to prevent failure of ABS valves and occurrence of error 00907.
When to turn to professionals
In some cases, self-repair can make things worse. If you do not have the skills to work with a multimeter or diagnostic equipment, it is better to entrust the work to specialists. Incorrect actions can lead to failure of the entire ABS unit, the cost of replacing which is much higher.
Contact a specialized service if the error is accompanied by strange sounds when the ABS pump is running or if not only the ABS lamp, but also the ESP indicator is burning. This may indicate a complex mechanical problem inside the hydraulic unit.
Professional assistance is also needed if the control unit is required. Modern cars Skoda Often require software updates to fix software bugs that cause false positives.
- 🔧 Lack of specialized diagnostic equipment.
- 📉 Complicated mechanical damage to the hydraulic unit.
- 💻 The need to reflash or encode new nodes.
⚠️ Warning: Never attempt to solder wires in an ABS harness without using quality insulation and shielding. Vibration and moisture can destroy the soldering site, which will lead to a new chain break.
