Hello
I removed one of the bungs this morning. It doesn't appear to be a drain of any type just a rubber bung & they definitely look like factory holes as they're very neat. Not sure if it's a good idea to leave the bung out, so perhaps water can get out (but then I suppose water could also get in too
)
I'm still not quite sure how water is supposed to drain from the sills if these aren't drain holes ??
Oh & a top tip if you take a bung out yourself, don't stick your little finger in the hole to see what's in there. I had an anxious minute when I couldn't get my damned finger out again
, so don't do that yourself
!)
Cheers
Dave
