My apologies for the delayed response. The car comes without any "roof" liner in the boot interior. Bare metal as pictured is what you should expect.

start by saying sorry for stealing this pics but i had to bridge a wire to get my boot open, then when i started to investigate i found a broken wire. the wire is on the left hand side inside the black rubber sleeve, i trimmed back the wire and re soldered a new piece of wire. total cost of an headache lol.

Outstanding guide Snoodini!
Thanks for the excellent pictures and step by step guide. I've got the same problem too with my 2008 S40 2.4i sedan...started out with an intermitent trunk (boot) light, now my trunk automatically unlatches when I start the car and the license plate lights are now out. All associated with numerous wires breaking in the trunk harness.
Looks like I can't ignore it much longer...thanks for the information! |

Updating on this thread to thank user for posting this guide
I followed the instructions for my 2004 S40 - a wire inside the plastic boot had snapped and was easily repaired and has worked fine for 2 years. My wife's 2010 S40 had the 'boot open light' warning and I traced it to the exact same area - she had a couple of badly frayed wires in the same plastic harness. However, I really had to 'pull down' on the plastic boot to expose the wires and effect a repair. I was frightened that if I'd pulled any firmer I may have snapped the whole loom, so I ended up cutting open the plastic boot entirely to access the wires. I've carried out the repair and the boot opens and closes fine now - but now I will need a new loom and plastic boot. My query is this: On the attached photo the loom goes into the main body of the car - where does it go from there? I can see from the guide where the wires appear to be connected to on the boot side - but where do they go internally? Homer |

Thanks Wooders! The US version of the Volvo S40 has the interior emergency boot release pull handle. Good thing too...my wiring has deteriorated to the point where the boot won't open using the exterior boot release handle and the infamous "Trunk Open" error on the dash display.
I've got the new wiring harness sitting in the kitchen...will install it this weekend! |

Earlier this summer, I had this same issue on my '09 S80, and I ended up brining it to the dealership for repair. However, this trunk release problem has now occurred on our '11 S40, so I ordered the part based on this post, and I will be making the replacement once it arrives. One question - does anyone know which fuse controls the trunk release? This was something that needed to be replaced as part of the repair on my S80, so I anticipate the same for the S40. Unfortunately, I can't find the fuse number for the trunk release within the owners manual for our S40. Any assistance would be greatly appreciated.

Thanks a million for this guide, both of mu number plate lights went out. After some search I found this fantastic guide which is a much needed help. I replaced the boot lid wiring harnesss and both lights are now working.

Excellent Guide
I have replaced my wiring harness using this guide, I could not open the boot so i had to go through the back seat, removed the carpet trim from inside and manage to connect the new harness without removing the three 10mm bolts and opened the boot.
Without this guide i would of taken this to my local garage for repair. I have attached pictures of the damaged harness. IMG_0305.JPG IMG_0306.JPG |
