Golf/GTI VI :: B Pillar Creaks Noise And Rattles

On my 2 door GTI, I had 2 rattles. One was coming from the door latch mechanism, and the other was coming from the black plastic b pillar trim. I picked up a can of "Blaster" silicon spray from Home Depot and sprayed just a little bit into the latching mechanism (on the door side). So far this has completely eliminated the knocking noise that I would hear in the door when driving over bumps.

On my drive afterwards, I kept hearing the infamous noise from the b-pillar trim, which seems to be a result of heat expansion when going from cold temp.... how the piece would sit there creaking when the car wasn't even moving. Anyways, I sprayed some of the silicon lube onto a q-tip and applied it to the edge of the plastic b-pillar trim that runs along the inside edge of the door. I guess I put enough on the q-tip to get it inside the edge of the plastic where it touches the metal of the door.

So far, my car is quiet as a mouse. It feels so good to have my car sound like the day I drove it off the lot!

Disclaimer: It could be a coincidence and perhaps the b-pillar had finally warmed up to a temp where it stopped creaking on its own, but it DID stop creaking as soon as I drove off after applying the lube. I'll post back if anything changes.
