Mein Auto: 1997 540i
Rear Tailights only work when I hit them

Hey guys so I own a 97 540i auto and the tail lights will only turn on if I physically get out of the car and tap lightly on them. they do not light up just by flicking the switch. I noticed a slight fray in the passengers wiring but i taped it. all bulbs have been replaced aswell.

My LCM also recently just went as I have no left headlight and marker light stays on after car is off ( only driver side stays on). could this be the same issue as my tail lights are not working or is it more likely wiring issues?

Check your tail light assembly for corrosion.

as impacting the assembly causes them to light up, the LKM is applying power to them. as jim said. check the connections. also, was the frayed wire due to abrasion, or did it get pinched? the wire itself might have broken conductors.

... especially the connector from the harness.

Make sure your battery is properly vented; look for corrosion in the tire well.

noticed the wire is damaged at the connector. is it possible to cut and replace the wiring or do i have to follow the whole harness and replace it all?

fix the wire, dont replace the whole thing (solder and heatshrink, dont twist together or use a wire nut)

Wire harness failure is pretty common. I had to solder a few wires. Bluebee has an extensive thread on it.
