Boot Lid Electronics Fail (no lights or central locking)

Post by Wavey Dynamicist » Mon Aug 15, 2022 9:39 am

Hi all,

Had a strange problem recently in which the boot lid electronics have failed which means no night lights, rear fog lights, number plate lights, central locking or boot interior light and the associated warnings.

My first reaction is fuse but i've not managed to confirm that yet and judging by some research that might not be the case and could be more so a wiring issue.

Any of you here had any experience of this? What was the fix?

Thanks,

If it's just the boot I'd check the cable that goes from the body through the tubing and into the bootlid. I had a similar thing with my drivers door, the main power to the control box had broken after being opened and closed so many times. Was a pretty simple fix, just added a new 5cm bit of wire to replace the broken section
