Airbag control unit with part number A082M6576F

What does the airbag control unit A082M6576F do?

The control unit A082M6576F controls the restraint system (SRS) of Lotus. It processes the measured values of the crash sensors and decides within milliseconds which airbags and seatbelt pretensioners are triggered. After an accident, it stores crash data and locks itself.

The monitoring runs in the background, without you noticing anything. Sensors, cable connections and actuators are checked continuously, and a fault that is found makes the airbag warning light in the instrument cluster come on.

The unit decides on triggering within milliseconds, which is why uninterrupted monitoring is particularly important.

Why does the control unit A082M6576F fail?

Most often the cause is stored crash data, even if no airbag has deployed. With this control unit, deleting the crash data is often not possible; if you would like it deleted, contact Airbag24 briefly before sending the unit in, so that they can check the part number. Other causes come into consideration as well, such as corrosion at plug connections or voltage spikes.

A normal diagnostic tool leaves crash data in place. A simple read-out is therefore not sufficient in such cases.

The other causes at a glance:

• aged electronic components in the control unit
• cold solder joints on the circuit board
• moisture and corrosion at plug connections
• voltage spikes, for example from a weak battery or jump-starting

How can you tell that the A082M6576F is defective?

The airbag warning light in the instrument cluster stays on permanently or comes on again and again. In addition there is an error message, no connection between the diagnostic tool and the control unit, and a fault memory that cannot be cleared. Airbags and seatbelt pretensioners may then possibly fail to deploy in a real emergency.

Even a single lighting up is reason enough to have the system checked, because the display reports a fault in the restraint system.

A missing connection to the diagnostic tool is also a sign that justifies a check.

Which vehicles is the A082M6576F fitted in?

The control unit A082M6576F is fitted in these vehicles: Lotus Esprit S4 (1993-1996) and V8 (1996-2004).

Here follows the list of the vehicles recorded for this number in our data.

• Lotus Esprit S4 (1993-1996)
• Lotus Esprit V8 (1996-2004)

Two steps help with the assignment. Compare the number on the label of the unit with this page, and you will know that it is the correct unit. Have the fault memory read out beforehand; only this result shows whether the control unit is defective or whether a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers A082M6446F.

How does the repair of the A082M6576F work?

First have the fault memory read out and enclose the log with the unit. Then disconnect the battery and remove the control unit. Next, create the repair order online and send the unit off well packed. Processing at Airbag24 usually takes 3–4 working days.

Do keep to this order, because airbag systems are safety-relevant and the battery must be disconnected before removal.

At Airbag24, the unit first goes to the test bench. Defective components are replaced, and a function test concludes the work. You then receive your own unit back, now repaired.

If you would like the crash data deleted, contact Airbag24 briefly before sending the unit in.

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.

How does the control unit A082M6576F get to Airbag24?

The unit goes to Airbag24 either as a parcel, or it is collected by UPS for an extra charge. It is returned by UPS after the repair.

Pack the control unit shockproof and put the printed repair order in the parcel.
