BMW 330d E91 - what are the purpose of these? - carnut1980

What are the purpose of these yellow ribbons? There are two, one by each bootlid hinge. The thin metal strip is severed in each one. They are about 2 inches long. They don't seem to do anything. They are damaged

Would they be affecting my remote locking, as my keys are good, but they don't work on the remote locking

remote locking now sorted. It wasn't the amp, it was a broken wire in the black rubber loom by the bootlid hinge! soldered back together, now all is fine!
