Hi all

Hope everyone safe under current circumstances.

I have the e350 cdi coupe on a 65 plate and have rain water trapped inside. From research it turns out the water gets trapped in the sills and to drain this , plastic drain plugs under the car need to be removed which are located next to the cars jacking points.

ive done this a few times but to be honest it’s becoming a pain to keep draining each time we have rain by having to remove the plugs each time. If I was to permanently remove the plugs would there be any issues ?

If it helps, the car doesn’t have a pano roof so no danger of any water getting in via this

thanks all
