On the very rare occasion you may need to remove the SAM, ensure that you take added care as damage of the SAM could result in a very costly bill. The SAM is the central control system and you can't run the car without it.

Never work on the SAM with the battery connected. As a starting point, disconnect the battery starting with the ground connection as follows:

Leave the car for at least 10 minutes to allow any residual charge to drain out of the electronics. The SAM is located within the left hand foot well. If your car is right hand drive then this is the passenger foot well. If it is a left hand drive then the SAM is under the steering wheel.

There is a release handle located as follows. Pull this and allow the SAM to drop at the front.

Push the top of the SAM upwards. You will feel it unclip from the hinged bracket.

You can now lower the SAM to reveal the connectors on the rear.

Now that the battery is disconnected, start unplugging the connectors from the back of the SAM. All of them have a little latch that needs pressing before you can pull the connector free.

If you have heated seats or a sliding roof then you will have a fuse carrier on the side of the SAM. To remove these, push the retaining tab back as shown and pull the fuse carrier free.

As you get to the connectors with several wires attached (at the furthest end), you need to swing down the grey arm before the connector comes free. The following sequence shows what you are trying to do.

The SAM should now only be attached with the big supply cable. The red blanking cover simply pulls off.

This revealed the 10mm securing nut which needs to be undone.

The SAM is now free to be removed from the car.
