Careful when buying used tail lights

First of all just wanted to say this post was excellent!

Has anyone come across a similar issue with their tail lights? It appears that the tail light I received has an issue with the sealing? Has anyone else had this and was able to fix?

Unfortunately, only solution is to return it to seller and ask for a new one.
I just hope it's not going to happen over time and that it was just a production issue they fixed.
Be sure to inspect them carefullly for an cracks of sealant.

Will do! I was able to get all the condensation out but I think I will just reorder this light and maybe sell to someone who is okay with just sealing it up themselves.

Cheers!

So, I finally gotten around to installing the LCI Tail lights; I've had them sitting in my house for about a year. No problems, everything went smoothly until I want to code. I had faults when I turn on the ignition which I ignored assuming they'd clear when the coding complete and most of them did however, two remain:

Collision Warning System inactive
Pedestrian Warning Malfunction

I've checked the coding and everything is correct but still, these two faults remain.

When I removed the OG tail lights, there were two (2) connectors going to each tail light, the 8 pin connector and a small 2 pin connector with two brown wires. In moving from the 8 pin to the 6 pin connector, I chose to remove the connector completely. I put some heat shrink on each of the two unused Brake wires and taped them back to the cable. I also wrapped the small connector in electrical tape and taped it to the cable. As both of those wires are brown, I suspect they are ground wires and I'm wondering if not having this cable connected is causing my problem?

One has nothing to do with the other, if you retrofitted the LCI taillights and coded it properly, there shouldn't be any related malfunctions, especially with the Drivers Assistant features, which run on a separate module, independent the lighting system.

In fact, the point of removing the warm/cold bulb checks, when the LED taillights are added is to avoid any errors.

After any coding session, the systems does a full reset and sometimes the Pedestrian Avoidance trigger a soft error but it is never permanent and usually clears itself after few seconds.

I suggestion you run diagnosis program or APP and try to see if it can pin point the exact related error codes(s). Then afterwards, maybe do another hard adaptions reset and see if the error(s) still lingers.

The extra [COLOR="DarkOrange"]brown[/COLOR] taillight wires are marked for ground but keep in mind, there are also three individual incandescent brake lights and specific wires for each light in the pre-LCI setup.

When you retrofit the LCI taillights, you discard two of them and since the LCI LEDs only require the use of one. So two of the extra wires are actually live brake wires that needs to be capped off, to avoid tripping a fuse.

Yes, you nailed it, the problem had nothing to do with the taillight retrofit.

Along with the tails, I installed the rear sound insulation and cleaned up/rerouted some other wiring. I accidentally disconnected the connector to the collision system switches in the lower left dash panel. I didn't actually disconnect it, it's was pretty loose and slipped out...I suspect the guys who installed my suspension broke the connector's locking mechanism. It's held in with tape now but I'll see about getting a new one from the stealer. All good, I'm pretty happy with everything. Thanks for the steer!
