Error 00907 on the instrument panel Ε koda Octavia A5 (2004–2013) is one of the most common problems faced by owners of this model. It indicates a malfunction in the system Tire Pressure Monitoring System (TPMS), but often its true causes lie deeper - from a banal sensor failure to serious problems with the wiring or control unit. In this article we will analyze in detail what the code means 00907 on Octavia A5 with 1.6 MPI, 1.8 TSI and 2.0 TDI engines, how to correctly diagnose the problem and what steps to take to eliminate it - from the simplest to the radical.

It is important to understand that ignoring this error can lead not only to false alarms of the pressure control system, but also to masking more serious malfunctions. For example, in some cases 00907 appears in parallel with errors CAN bus or comfort block (J393), which requires an integrated approach. We have collected the experience of car owners, manufacturer's manuals and recommendations of service centers to provide you with the most complete and structured information.

What does error 00907 mean on the Ε koda Octavia A5?

Code 00907 in the self-diagnosis system Octavia A5 stands for "Malfunction in the tire pressure sensor circuit" (Tire Pressure Monitoring System β€” TPMS). However, this general description is often misleading. In practice, the error may indicate:

  • πŸ”‹ TPMS sensor malfunction (physical damage, battery discharge or electronic failure).
  • πŸ”Œ Wiring problems between the sensor and the control unit (J502 β€” Gateway or J393 β€” BCM).
  • πŸ–₯️ Control unit failure (for example, after flashing or a power surge).
  • πŸš— Sensor incompatibility (if non-original or used components were installed).

It's interesting that on Octavia A5 with the system First generation TPMS (before facelift 2008) error 00907 often accompanied by a flashing tire pressure indicator on the dashboard. On models after 2009 (from Second generation TPMS) an additional message may be displayed "Check Tire Pressure", even if the pressure is normal.

According to service center statistics, in 60% of cases the problem is solved by replacing the sensor or reflashing it, in 25% - repair of wiring, and only in 15% intervention in the control unit is required. However, without an accurate diagnosis, these numbers mean little.

πŸ“Š How often do you get error 00907?
  • Constantly on
  • Periodically (once a week)
  • Rarely (once a month)
  • Only after washing or rain
  • Another option

Reasons for error 00907: from simple to complex

To effectively resolve an error, you need to understand its root cause. We have systematized all possible causes, ranking them by frequency of occurrence and complexity of elimination.

Reason Frequency of occurrence Difficulty in eliminating Approximate cost of repair (rubles)
TPMS Sensor Battery Low 40% Low 1,500–3,000 (sensor replacement)
Sensor damage (corrosion, mechanical stress) 25% Average 2 000–4 500
Broken or shorted wiring to the sensor 15% High 3,000–8,000 (depending on damage area)
Control unit firmware failure J502 or J393 10% Very high 5,000–15,000 (flashing or block replacement)
Incompatibility of sensors (for example, after changing wheels) 10% Low 1,000–2,500 (reprogramming)

Particular attention should be paid TPMS sensors. On Octavia A5 Two types of sensors were installed:

  • πŸ”΄ First generation (until 2008) - operate on the frequency 433 MHz, have a removable battery (type CR2032).
  • 🟒 Second generation (after 2008) - frequency 315 MHz, battery is soldered in, service life ~7–10 years.

If your car has sensors first generation, there is a high probability that the problem lies in a dead battery. For sensors second generation Failures are typical after changing wheels (for example, when switching to winter/summer tires), when the system does not recognize new identifiers.

⚠️ Attention: If the error 00907 appeared after visiting a tire shop, with a high degree of probability the problem is damage to the sensor when beading the wheel. Some service stations use non-specialized equipment, which can break the sensor housing.

Diagnosing error 00907: step-by-step instructions

Before you begin repairs, you need to pinpoint the source of the problem. This will require diagnostic scanner (for example, VCDS, OBDeleven or Launch X431) and a multimeter. Below is an action algorithm that will help narrow down the range of possible malfunctions.

Connect a scanner and read errors from the block J502 (Gateway) and J393 (BCM)

Check for additional errors using CAN bus (for example, U112100 - connection loss)

Measure the wiring resistance from the TPMS sensor to the control unit (standard: 0.5–1.5 Ohm)

Check the voltage at the sensor contacts (should be ~12V when the ignition is on)

Reset errors and check if they appear again after restarting the engine-->

Step 1. Reading errors with the scanner

Connect the diagnostic cable to the connector OBD-II (located under the steering wheel, to the left of the brake pedal). In the program VCDS select:

Select β†’ 19-CAN Gateway β†’ Fault Codes (DTCs)

If in addition 00907 there are type errors U112100 or U012100, this indicates problems with CAN bus. In this case, you first need to eliminate the connection breaks.

Step 2: Check TPMS Sensors

Each sensor has a unique ID, which can be considered a scanner. To do this:

Select β†’ 65-Tire Pressure β†’ Advanced Identification β†’ Start Search

If one or more sensors are not detected, the problem lies with them. It is also worth visually inspecting the sensors for corrosion or mechanical damage (especially after wheel trim).

Step 3: Check the Wiring

For this you will need a multimeter. Disconnect the TPMS sensor connector (located on the inside of the wheel, next to the valve) and measure:

  • πŸ”‹ Voltage between contacts +12V and GND (should be ~12V when ignition is on).
  • πŸ”Œ Resistance between the sensor contact and the control unit (norm: up to 1.5 Ohm).
⚠️ Attention: On Octavia A5 with engines 2.0 TDI (CBAB) and 1.8 TSI (CDAB) control unit J393 Particularly sensitive to power surges. If, when checking with a multimeter, the voltage at the sensor exceeds 14.5V, this may indicate a malfunction of the generator or relay regulator.
πŸ’‘

If you do not have a diagnostic scanner, you can try to reset the error manually: hold down the button SET/RESET on the steering column switch (right) for 10 seconds with the ignition on. This will only work if the problem was temporary (eg communication failure).

How to resolve error 00907: from simple to radical methods

Depending on the cause of the malfunction, ways to resolve the error 00907 can range from basic to requiring specialist intervention. We will analyze all possible options, starting with the simplest.

1. Reset the error and reboot the system

B 30% of cases the error appears due to a temporary failure in the control unit. To exclude this option:

  1. Connect the scanner and clear the error 00907.
  2. Disconnect the battery for 10–15 minutes (by removing the terminal "βˆ’").
  3. Reconnect the battery and start the engine.
  4. Do a 5-10 km test drive while watching the instrument panel.

If the error does not appear again, the problem was temporary. Otherwise, continue to the next step.

2. Replace the battery or TPMS sensor

If the sensor first generation (with a removable battery), you can try replacing the battery:

  • πŸ”§ Carefully disassemble the sensor housing (usually it is twisted or held on by latches).
  • πŸ”‹ Replace the battery with a new one (CR2032 or similar).
  • πŸ”„ Reprogram the sensor via the scanner (in the menu 65-Tire Pressure β†’ Adaptations).

For sensors second generation It is not possible to replace the battery - you will need to purchase a new sensor (original article number: 5K0 907 273 for front wheels, 5K0 907 274 for the rear). Average cost: 2 000–3 500 β‚½ per piece.

3. Wiring repair

If the diagnostics show an open or short circuit, you will need:

  1. Remove the wheel and inspect the wiring harness leading to the sensor.
  2. If damage is detected, clean and solder the wires, insulating them with heat shrink.
  3. Check the integrity of the shielding braid (damage to it may cause interference).

On Octavia A5 most often the wires in the area fray right rear wheel (due to the close location to the suspension elements).

4. Reflashing the control unit

If the error is accompanied by other codes CAN bus (for example, U012100), the unit's firmware may need to be updated J502 or J393. This is a complex procedure that is best left to specialists. Average cost: 5 000–10 000 β‚½.

In rare cases, the control unit fails completely. In this case, it will need to be replaced (price of a new one: 15 000–25 000 β‚½, used: 8 000–12 000 β‚½).

πŸ’‘

Before replacing the control unit, be sure to check the voltage in the on-board network. If it exceeds 14.5V, first eliminate the cause of the overvoltage (most often the generator relay regulator is to blame).

Frequently asked questions and misconceptions about error 00907

Around the error 00907 There are many myths circulating. Let's look at the most common of them.

Myth 1: "The error only appears in winter due to low tire pressure."

πŸ”Ή Reality: TPMS system on Octavia A5 takes into account temperature fluctuations and corrects readings automatically. If the error appears at low temperatures, the problem is most likely in low sensor battery (lithium cells lose capacity in the cold).

Myth 2: "You can simply disable TPMS in settings and the error will go away."

πŸ”Ή Reality: On Octavia A5 it is impossible to disable TPMS programmatically - the system is integrated into CAN bus. The only way to β€œremove” the error is to physically disconnect the sensors, but this will lead to a constant light on the malfunction indicator.

Myth 3: "Error 00907 does not affect the operation of the car, you can continue driving."

πŸ”Ή Reality: The error itself does not block the car's systems, but it can mask more serious problems, for example:

  • πŸ”₯ Short circuit in wiring, which over time can lead to fire.
  • πŸ–₯️ Failures in the control unit, due to which later errors may appear on other systems (for example, ABS or ESP).
Why does error 00907 often appear after washing?

The cause is usually water getting into the TPMS sensor connector or contact corrosion. The sensors on the rear wheels are especially vulnerable due to their close location to the arches. To avoid the problem, after washing it is recommended to blow out the connectors with compressed air or treat them WD-40 (not a lot!).

Is it possible to drive with error 00907 if the tire pressure is normal?

Short-term - yes, but it is not recommended to postpone repairs for a long time. The error may indicate problems with the wiring or control unit, which will worsen over time. For example, a broken wire can lead to a short circuit, and a fault in J393 - to non-working power windows or central locking.

How much does it cost to replace the TPMS sensor on an Octavia A5?

The cost depends on the type of sensor and installation location:

  • πŸ”§ Original sensor (new): 2 000–3 500 β‚½ per piece.
  • πŸ”§ Analogue (for example, ATE or Huf): 1 200–2 500 β‚½.
  • πŸ”§ Replacement + programming in the service: 500–1 500 β‚½ per wheel.

Tip: When replacing sensors on all four wheels, you can save money by purchasing a kit (for example, TRW or Schrader).

Can I reflash TPMS sensors myself?

Theoretically yes, but for this you need a diagnostic scanner with support for adaptations (for example, VCDS or ODIS). Algorithm:

  1. Connect the scanner and select the block 65-Tire Pressure.
  2. Go to Adaptation β†’ Channel 01.
  3. Enter new ID sensors (indicated on their body).
  4. Save your settings and take it for a test drive.

⚠️ Important: If entered incorrectly ID the system may lock up and require a reset via Dealer Mode.

Why does error 00907 only appear on one wheel?

This is a typical sign malfunction of a specific sensor or wiring damage to him. Most often it suffers:

  • πŸ”„ Right rear wheel - due to chafing of wires on suspension elements.
  • πŸ”„ Left front wheel β€” due to moisture getting into the connector (close to the windshield).

Recommendation: Start by visually inspecting the sensor and checking the wiring resistance with a multimeter.

What other errors may appear along with 00907?

Frequent "companions" 00907:

  • U012100 β€” loss of communication with the control unit J393.
  • C102700 - malfunction of the ABS sensor (may be associated with a break CAN buses).
  • B10CD04 β€” failure in the comfort system (central locking, power windows).

If together with 00907 other errors are displayed, first fix the problems with CAN bus or food.
