Airbag control unit with part number 992959655E

What does the airbag control unit 992959655E do?

The airbag control unit 992959655E runs the SRS restraint system in Audi, checks the crash sensors and determines, in a crash, the deployment of airbags and seatbelt pretensioners. It signals faults via the airbag warning light. After a crash, it stores crash data and locks itself.

In an emergency the unit reacts within fractions of a second, so it works without interruption while the vehicle is powered up.

The unit stores detected faults in the fault memory.

Why does the control unit 992959655E fail?

Causes with the 992959655E: stored crash data from an accident is the most common cause, even if no airbag has deployed. Aged components, moisture and voltage spikes are also possible. With this control unit, it is often not possible to erase the crash data; if you would like it erased, get in touch with Airbag24 briefly before sending the unit in.

Crash data remains in the control unit after an accident, even if the car keeps driving. A normal diagnostic tool cannot erase it.

Aged components, cold solder joints and moisture at the plug connectors can also cause the unit to fail.

Voltage spikes, for example from a weak battery or a jump start, also count among the triggers. Which cause applies in an individual case is only shown by the inspection.

How can you tell that the 992959655E is defective?

Signs at the 992959655E: a fault shows up as the warning light in the instrument cluster, which stays on permanently or intermittently. An error message in the instrument cluster may also appear. In an actual crash, the airbags and seatbelt pretensioners could possibly fail to deploy.

The warning light reveals a fault directly, so do not ignore it. Have the system checked promptly.

A lack of communication with the diagnostic tool is also a warning sign. If the fault memory stays full after an attempt to clear it, that too indicates a fault.
