Diagnostic Trouble Codes for Skoda Octavia cars (error codes with descriptions)

For the owner, the condition of the car plays a key role. 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 and how to diagnose Skoda Octavia on your own, as well as about adapters and computer programs that will help decipher the data.

All three Skoda Octavia generations on the market – the A5, A7 and Tour – are high-tech cars, literally stuffed with various electronics. Airbags, climate sensors, EPC, ESP systems, 1.6 BGQ 1.8 electronic engine control units are the norm rather than the exception.

How to check the error codes on the Tour and all subsequent generations of Skoda Octavia? How to find out if the climate control system, airbags, EPC and ESP systems work correctly?

For such an operation, there is a diagnostic connector that is controlled by the program.

That is, having a laptop on hand, systems such as airbags, climate control, EPC system and BFQ engine electronics and other markings can be checked using the software and adapter, which is freely available in most specialized electronics stores.

At the moment, there are only two adapters on the market that read data about EPC and other electronics. They connect to the OBD connector, the location of which is indicated 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.

Wired adapter VAG-COM works with a connector and serves as diagnostic equipment.

A program installed on a laptop or netbook communicates with an adapter connected via a connector and reads error codes. Next to the code is its interpretation. You can easily find out which of the systems on the Skoda Octavia is out of order.

Another model of the 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 of liftback.

The only difference is the more powerful functionality of the computer program and the ability to recognize 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.

Skoda Octavia Fault Codes list

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.

Summing up

Timely diagnostics of faults on the Skoda Octavia A5, Tour and a newer generation – the key to long-term and trouble-free service car. If you regularly check all the nodes and systems, you can avoid unexpected breakdowns and extend the life of your car several times.
