When the boot/trunk is shut you dont know its missing its there to stop the bumper flexing and add additional fixing clips its the only removable piece of plastic behind the bumper below the boot so you will know what I am talking about.ĥ. I ordered a new one but left this piece off the car until it arrives so I can still drive the car. Remove the screws holding the piece of long plastic (about length of the boot under the boot behind the bumper) you have the option to cut this down with a hacksaw or use a grinder eg put a curve on it so the new bumper fits over it (we are talking 2-3cm of plastic to cut off it) or order a new one for the 2007 model. If you do remove the frame surround there are 3 really easy to see screws on top then one hidden one in the corner which you can unscrew and remove once the bumper is removed.Ĥ.
I have ordered the frame surrounds but it looks like they will need paiting so unlike me, better to get it done with the bumper at the same time! Look at the pics and see if its something you dont mind (the small gap) its all water tight so its purely costmetic issue. The downside to doing this is you wil see a bit of a gap in the top left and right hand corners when the new lights are fitted, but it still looks 100% better than the old lights! So its your choice. Frame surrounds: You have a choice, the old frame surrounds for the lights (these are the painted pieces of plastic that sit above the lights) it will work to an extent if you cut of the small lugs that stick down where the old light fits into. You then tug hard on lip nearest the wheel arch and it all comes away. Bumper Removal: The bumper removal is pretty straight forward, 5x 9mm bolts underneath, then 3 press in studs in each wheelarch which pull out with pointed nose pliers. Remove old tail lights by undoing 3 nuts behind each light clusters, unplug the 1 cable and it should then pop out.Ģ. Soldering Iron (of you can use those horrble press splice connections)ġ. I will be avoiding buying the expensive light control module needed to run the facelift lights by doing a bit of simple electronics!

Navcoder lcm how to#
Hi All, I have been lurking round these forums for quite a few years so thought I would do a how to on updating the rear lights from 2004 to 2007 model. NavCoder can change the coding for you.**** EDIT 2020, Fixed the images, note there is a better way to reprogram the LCM with NCS Expert so steps 5 onwards can be done by reprogramming to remove the T effect. If the lamp failure is not detected, then fit a different relay with a lower current draw.ĭid you fit a PAL or NTSC camera? If PAL, you'll need to change the coding on the Video Module (default = NTSC) You can test by having a relay connected and removing one reverse lamp bulb - see if the lamp failure is detected :-) Relay current draw is not enough to upset the lamp check circuitry. The tie-down hooks have a small plastic cover on top of the bolt, lift the cover off with eg a jewelers screwdriver. You'll have to unbolt the floor tie-down hooks to lift the floor panel. Much easier than working inside the tailgate.
The video module is located under the floor panel, right behind the rear seats, so the wire from the loom to the video module only needs to be about 1 m long. Note that the reverse lamsp are not active when towing (with the original BMW trailer module), if you want reverse camera active in this situation, use the LCM RFSI signal to activate the relay (5V low current relay required) E39 Touring has the following reverse light wires: Remove the rear seat base and RH rear seat squab to access the wiring loom, then you can pick out the reverse light wire and tap into it. That's the pillar just behind the rear seat. Ive also read confusingly that the reverse signal polls for bulb failure and would connecting a relay upset this or possible cause video signal dropoutsĮ39 Touring Tailgate wiring loom runs down the right hand side C-pillar from roof to floor. Other option is to fit the relay inside the tailgate itself next to camera and extent the video module reverse ground trigger pin17 back into the tailgate and relayĪnyone with any wiring circuits that show access to the reverse light signal 12v+ DOH,Is there anywhere in the RH rear of car (video module corner) that I could tap into the reverse signal,cant find where the tailgate light wires go once they enter the roof space above the rear roof speakers but suspect they dont return to the rear of the car.

After viewing many reverse camera install retrofit diagrams Ive fitted an aftermarket reverse camera to an e39 wagon but have suddenly realised when going to fit the relay for 12v+ reverse wiring trigger that the reverse lights are actually in the tailgate.
