I have a 2011 328i and when I got inside yesterday (after it rained) I noticed the carpet near the footrest and around that area was wet. It's only on the drivers side that there's water leaking. The cowl drains under the hood on each side are cleaned. I tried spraying water with a hose around the area to see where the leak was but I couldn't pinpoint the leak. There's no water stains on the headliner or anywhere else. Anyone have an idea where this leak could be from?
