Thank you mate sorry for the slow reply’s So I removed the frm module checked it out appears fine removed checked and reinstalled every single fuse in the junction box electrics all appear fine I check the DDE last week that seemed fine as well as all the connectors so I’m stumped I guess I will have to check all my ground connections and and the fuel pump module I’m still needing to scan the car again to check if there are any new codes 

Thank you so much for your reply mate I haven’t checked any fuses I’m a bit clueless when it comes to electrical issues but I will 100% give all the fuses a look at I removed the DDE and all the male pins on the DDE and the plug connectors looks I do remember the ista saying no communication to the JBE as well I forgot to take a picture of it, it also mention no communication to the frm and check the fuses and terminal 15 but I don’t know what that is 😂

yes the car does turn over

I was driving down the road and the car decided it no longer wanted to run I have the scan tool software rac told me it needs a new fuel pump in the tank but im not so sure after seeing the codes has anyone experienced this before 

Thank you mate you’ve been super helpful 

Also I have these two cables left over one that runs along the main electrics and another that just comes from under the boot that trails into the battery tray area 

Would you know if these two cables are for the original electric plug next to the tow bar 

Thank you so much mate you’ve helped loads I don’t know anything about bmw so the links and everything your telling me is extremely helpful so thank you mate

Thank you for the fast reply greydog I went out this morning and removed the mess it looks like at some point the original wiring for the trailer electrics have failed and the previous owner has failed at installing a kit I’ve removed all the bodged electrics and used electrical tape on any exposed wires So it’s all completely safe and somewhat original now it also looks as if the rear parking sensors have failed as there’s a few more wires coming from the rear bumper up into the area where the battery tray is I’ve just taped up the wires just so they don’t get damaged and placed them to one side but does anyone know if I need to keep the wiring box that’s in the picture below please

Hi I’m new to owning a bmw 320d the other day I was looking in the boot for my wheel locking nut after a week of owning the car I remove the cover for the battery (unaware what it was at the time) to discover a mess of wires and I need help I believe the previous owner has tried to install a trailer wiring harness and failed horribly now I have to fix this dangerous mess can anyone locate me in the correct direction please as to what might be for what I know it’s a long shot but I’m hoping there’s a knowledgeable person that see this and can point me in the right direction thanks
