Skoda Epiq 1 airbag control unit repair

What is a Skoda Epiq 1 airbag control unit?

The airbag control unit in the Skoda Epiq 1 is the central controller of the restraint system (SRS). It reads the signals from the crash sensors and, in an accident, decides within milliseconds which airbags and seatbelt pretensioners deploy. It also monitors the system constantly and indicates faults with the airbag warning light.

The Skoda Epiq 1 (since 2026) is fitted with this unit from the factory. It works together with the sensors and the airbag modules. The sensors supply measured values. The control unit evaluates them and enables ignition.

It runs a self-test at every start. If it detects a fault or implausible values, the warning light comes on. After an accident, the unit stores crash data and locks itself.

Why is the Skoda Epiq 1 airbag control unit defective?

Most often the cause is crash data stored after an accident, even if no airbag deployed. Ageing electronic components, cold solder joints, moisture and corrosion on connectors may also be responsible, as may voltage spikes from a weak battery or jump-starting.

A normal diagnostic tool cannot remove stored crash data. The control unit therefore keeps reporting as locked, even if the damage to the vehicle was repaired long ago.

A typical sign is an airbag warning light that stays on permanently. Other indications: the fault memory cannot be cleared, or the diagnostic tool cannot establish a connection. With ageing components and damp connectors, the light often comes on only intermittently at first and then goes out again.

Common error codes for Skoda Epiq 1 airbag control unit repair

The codes of this vehicle report internal faults of the control unit, stored crash data, missing communication, faults in the supply voltage and problems in the firing circuits.

These error codes are known in connection with the airbag control unit of this vehicle:

• 65535 → Internal fault in the airbag control unit
• 00595 → Crash data stored, airbags and seatbelt pretensioners deployed
• 01214 → Crash data stored for seatbelt pretensioner
• 01226 → Crash data stored, driver-side side airbag
• 01321 → No signal from the airbag control unit
• U0151 → Communication with the airbag control unit lost
• 00532 → Supply voltage outside the permissible range
• 00588 → Driver airbag firing circuit: short circuit or resistance out of tolerance

A diagnostic tool reads out the error codes. However, a single code does not prove that the control unit is defective. Connectors, wiring or an airbag module may also be the cause. Only testing shows where the fault lies.

What part numbers are available for the Skoda Epiq 1 airbag control unit repair?

You will find the part number on the label of the control unit. It determines the exact version, because depending on equipment and year of manufacture the numbers differ within a model series.

Airbag24 currently has no part numbers on file for this vehicle. Please read the number from the label yourself and enter it in the repair order. This lets us assign your unit correctly. Whether it is defective is only determined by reading out the fault memory or by testing.

The process is straightforward. 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. Checking, repairing and testing usually take 3–4 working days at Airbag24. 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.
