B pillar drains

Post by dazthephot »

Hi, can anyone share a pic of the B pillar drains? I’m chasing the source of water in the boot still.
There’s too much water for it to be the 3rd brake light and the aerial grommet is new. The left side is proper topped up and so is the battery tray. So annoying.
Thanks.

Look behind the hood hinge point on each side you will see a metal well capped with a rubber trim around the edge, the drain hole in inside this, a tube runs down and exits at the bottom of the sill just in front of the rear wheel.

Best poke some wire down the drain hole to see if they are blocked, if you pour a small amount of water in from the top you should saee it drain out under the sill outlet.

Thank you very much. I did wonder if it was there, now I know.
