Error code 128 appears on the display of the instrument cluster of the Opel Insignia mk2 when the front bonnet is open. To remove the code, switch off the instrument cluster, close the bonnet, and turn the instrument cluster back on. If the error code continues to appear, there is a decoding issue with the control unit.

You will need to visit a workshop for a computer diagnosis to reset the code completely and reprogram the control unit if necessary. The cost for reprogramming is around £300.

How to Remove the Rear Seat of a Hyundai Tucson?

To remove the rear seat of a Hyundai Tucson, follow these steps. Start by moving the front seats to their most forward position to gain space. Next, locate the release lever on the underside of the rear seat, near the floor. Press this lever down while pulling the seat upwards to unlock it from the anchor pins. Once unlocked, tilt the seat upwards and forwards to remove it from its position. Repeat this process for both sides of the rear seat. Be careful of any electrical cables or components that may be connected to the seat during removal. Once the rear seat is removed, the disassembly is complete.
