Volkswagen T-Roc 2nd generation airbag control unit repair

What is a Volkswagen T-Roc 2nd generation airbag control unit?

The airbag control unit is the central control unit of the restraint system (SRS) in the Volkswagen T-Roc 2nd generation. It evaluates the signals from the crash sensors. In an accident, it decides within milliseconds which airbags and seatbelt pretensioners deploy.

The unit works in the background. It monitors the system continuously. If it detects a fault, it reports it via the airbag warning light.

The control unit is fitted in the Volkswagen T-Roc 2nd generation (since 2025). After an accident, it stores crash data and locks itself.

Why is the Volkswagen T-Roc 2nd generation airbag control unit defective?

The most common cause is crash data stored after an accident, even if no airbag deployed. A standard diagnostic tool cannot delete it. Other causes include aged electronic components, cold solder joints, moisture and corrosion on connectors, and voltage spikes.

Crash data is created when the control unit registers an impact. An airbag does not have to fire for this. The entry stays in the unit. A standard diagnostic tool does not delete it. As long as it is stored, the airbag warning light stays on, and the system is considered not ready for use.

Electronics age even without an accident. Solder joints lose contact. Moisture makes connectors corrode. Voltage spikes damage components, for example with a weak battery or when jump-starting.

Typical signs: The airbag warning light stays on permanently. The fault memory cannot be cleared. The diagnostic tool cannot establish a connection.

Common error codes for Volkswagen T-Roc 2nd generation airbag control unit repair

The error codes indicate internal control unit faults, power supply faults, faults in the airbag firing circuits and stored crash data. They narrow down which area of the system the fault is in.

These codes occur on this vehicle. They help you and the workshop narrow down the search for the cause.

• 65535 → Internal memory fault in the control unit
• B2013 → Data record missing in the replacement control unit
• 00595 → Crash data stored, impact detected
• 01226 → Crash data stored, driver airbag
• 00532 → Supply voltage outside the permissible range
• 00588 → Driver airbag firing circuit: resistance out of range or short circuit
• 00589 → Front passenger airbag firing circuit: resistance too high
• 01217 → Side airbag firing circuit, driver side: circuit fault

A diagnostic tool reads out the codes. A code alone does not reliably show that the control unit is defective. Connectors, wiring or an airbag module can also be the cause. Only the inspection will clarify it.

What part numbers are available for the Volkswagen T-Roc 2nd generation airbag control unit repair?

The part number is printed on the label of the control unit. It determines the exact version, because within a model series there are different numbers depending on equipment and year of manufacture. For the Volkswagen T-Roc 2nd generation, there is no list of known numbers yet.

Therefore, read the number directly from the label of your unit. Enter it in the repair order. This is how we match your unit to the correct version. Make sure you copy the number completely and legibly.

The number only ensures that it is the right unit. Whether it is defective is shown only by reading out the fault memory or by the inspection.

The route to repair is short. First have the fault memory read out. Then disconnect the battery and remove the control unit. Create a repair order online and send in the unit. Processing at Airbag24 usually takes 3–4 working days and covers testing, repairing and checking, not shipping.

The repaired control unit comes back with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.
