Airbag control unit with part number 6R0959655L

What does the airbag control unit 6R0959655L do?

The airbag control unit 6R0959655L coordinates the SRS of Seat and Skoda: it reads the crash sensors, determines within milliseconds in an accident which airbags and seatbelt pretensioners are triggered, and monitors the system continuously.

Faults appear via the airbag warning light. After an accident, the unit stores crash data and locks itself. The monitoring serves to report deviations early.

Why does the control unit 6R0959655L fail?

Crash data stored in the unit after an accident is the most common cause, even if no airbag was triggered. A normal diagnostic tool cannot erase it. Other causes are aged electronics, cold solder joints, moisture and corrosion, and voltage spikes.

What matters for crash data is the storage, not the triggering of an airbag. Airbag24 takes care of erasing it during the repair.

Components age over time, solder joints can go cold, and moisture attacks plug connections. Voltage spikes occur, for example, with a weak battery or a jump-start.

How can you tell that the 6R0959655L is defective?

A defect shows itself through the airbag warning light in the instrument cluster, which lights up constantly or intermittently. An error message in the instrument cluster, a missing connection to the diagnostic tool, or a fault memory that cannot be cleared also indicate it.

These signs in detail:

• Airbag warning light lights up constantly or intermittently
• Error message in the instrument cluster
• The diagnostic tool finds no connection to the control unit
• The fault memory cannot be cleared

In an emergency, airbags and seatbelt pretensioners may then fail to trigger. Such a warning signal must therefore be taken seriously.

First compare the part number on the label of the removed unit with this page; this only shows that it is the right unit. Whether the control unit itself is defective is shown only by the fault memory, which you have read out beforehand, because a plug or a cable can also cause the fault.

For the same vehicles, we also repair control units with the part numbers 1C0 909 605 F, 1C0 909 605 K, 5WK43125, 5WK43131, 6C0 959 655 J, 6C0959655L.

How does the repair of the 6R0959655L work?

First have the fault memory read out and enclose the log, then disconnect the battery and remove the control unit. Afterwards, create a repair order online. Processing at Airbag24 usually takes 3–4 working days.

Then send the unit in well packed. At Airbag24 it is examined on the test bench, defective components are repaired, stored crash data is erased and a function test runs. After that, you receive your own unit back.

Our repairs come with 2 years' statutory liability for defects. 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.
