Diagnostic trouble codes for the Skoda Octavia (fault codes with descriptions). The condition of the car plays a key role for the owner. Normal operation of airbags, climate control, ESP and EPC systems is the key to safe movement in your own car. Today, we will tell you how to diagnose your Skoda Octavia yourself, as well as about adapters and computer programs that will help you decipher the data.
All three generations of the Skoda Octavia on the market – the A5, A7 and Tour – are high-tech cars, literally stuffed with all kinds of electronics. Airbags, climate sensors, EPC, ESP systems, 1.6 BGQ 1.8 electronic engine management systems are the norm rather than the exception.
How to check the fault codes on the Tour and all subsequent generations of the Skoda Octavia? How to find out if the climate control, airbags, EPC and ESP systems are working correctly?
For such an operation there is a diagnostic connector controlled by the programme.
This means that if you have a laptop at hand, you can check systems such as airbags, climate control, EPC system and BFQ engine electronics and other markings using the software and adapter, which are available free of charge in most specialist electronics shops.
There are currently only two adapters on the market that read data from the EPC and other electronics. They connect to the OBD connector, located at the bottom of the torpedo above the driver’s left foot, and work through a computer program on both BFQ and more powerful engines.
The VAG-COM wired adapter works with a connector and serves as a diagnostic tool.
A program installed on a laptop or netbook communicates with an adapter connected via a connector and reads fault codes. Next to the code is its interpretation. This makes it easy to find out which of the Skoda Octavia’s systems is faulty.
Another model of diagnostic adapter that works through a computer program is VAS 5054a.
This adapter also works through communication via the diagnostic connector on the Skoda Octavia Tour, A5 and the latest generation Liftback.
The only difference is the more powerful functionality of the computer program and the ability to recognise a greater number of faults received from the connector.

Key moment
The fault codes table read from the Skoda Octavia Tour and newer generations has a similar structure. In the left column is the code itself, and in the right is its full identification. As a rule, the system automatically generates a decryption for each individual block, but if this does not happen, you should refer to the reference data.
Thus, the malfunction of the airbags at Skoda has the cipher P0326. However, on the Tour in this case, the corresponding light on the dashboard will light up. She warns that the pillow sensor system requires intervention.
The same applies to the ESP system, whose work is directly related to the work of both the front and rear suspension. In the event of a failure of any of the suspension elements, the system will certainly fail and produce the value P0335. Often, such a malfunction of the ESP system is accompanied by malfunctions of the ESC system, which is also responsible for the stability of the Tour on the road and the stabilization of course stability.
The ESC system malfunction has the P0343 cipher on the tour. At the same time, the ESC error will be displayed on the on-board computer, which will need to be detected using the equipment, erased and replaced the faulty unit.
In addition to the ESC system, on the 1.6 BFQ engine blocks there may be an error in the EPC sensor, which is responsible for the electronic brake pedal. The failure of the EPC and ESC systems can be blamed on the soured or outgoing contacts of the electronic unit itself, as well as the use of low-quality fuel for refueling Skoda Octavia.
In addition to such BFQ systems, the engine electronics of the Tour can often fail. The table shows that separate values exist for the skips of all four cylinders, electric chains of the fuel pump, spark plugs and systems for regulating the quality of the fuel mixture.
Climate control system error on BFQ is P0501. Climate control sensor does not produce errors on the dashboard, and this fault can only be seen through more detailed diagnostics.
