Airbag control unit with part number A132M0208F

What does the airbag control unit A132M0208F do?

The airbag control unit A132M0208F coordinates the restraint system (SRS) of Lotus. From the signals of the crash sensors, it calculates within milliseconds which airbags and seatbelt pretensioners to trigger in an accident, and monitors the entire system continuously.

The unit shows detected faults via the airbag warning light in the instrument cluster. This tells the driver that the restraint technology is no longer fully ready.

After an accident, the control unit creates crash data and locks itself. You will find more on the causes of a failure in the following section.

Why does the control unit A132M0208F fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed. With this control unit, this data often cannot be deleted; if you wish, contact Airbag24 briefly before sending the unit in. Other causes are aged components, cold solder joints, moisture and corrosion, and voltage spikes.

A conventional diagnostic tool cannot remove this data. Whether or not the airbag has deployed makes no difference.

In detail, the following points may apply:

• electronic components that age over time
• solder joints that are cold or cracked
• moisture and corrosion in the plug
• voltage spikes, for example from a weak battery or jump-starting

How can you tell that the A132M0208F is defective?

A defect shows through signs that the unit reports itself or that become apparent during a read-out. In a real emergency, airbags and seatbelt pretensioners could then possibly fail to deploy.

The signs in detail:

• airbag warning light in the instrument cluster that stays on permanently or only intermittently
• error message in the instrument cluster
• no connection from the diagnostic tool to the control unit
• fault memory that cannot be cleared

Which vehicles is the A132M0208F fitted in?

The control unit A132M0208F is fitted in these vehicles: Lotus Evora (2009-2021). The list serves as a guide; the removed unit with its part number remains decisive.

These are the vehicles assigned to this part number:

• Lotus Evora (2009-2021)

Before removal, the following is important. First, have the fault memory read out, because only this result shows whether the control unit itself is defective or whether a plug or cable is the cause. Second, compare the part number on the label of the removed unit with this page; this only ensures that it is the correct unit.

For the same vehicles, we also repair control units with the part numbers B132M6067F, B132M6206F.

How does the repair of the A132M0208F work?

First have the fault memory read out and enclose the log, then disconnect the battery and remove the control unit. Next, create a repair order online and send the unit in well packed. At Airbag24, the checking, repairing and testing usually takes 3–4 working days.

At the Airbag24 test bench, the unit is first examined; defective components are then replaced, and a function test concludes the work. Only after that is it returned to you. If you want the crash data removed, discuss this with Airbag24 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 A132M0208F get to Airbag24?

Either you send the unit as a parcel, or you book a UPS collection for an extra charge. The return after the repair is likewise made by UPS.

The printed repair order belongs in the parcel. Make sure to pack the control unit shockproof.
