Rubber plugs on frame below doors
Hello-
New owner of a W116 (300SD) with a question. I was working on my car yesterday and I noticed a series of what look like plugs running along the underside of the car, between the front and rear jackpoints. What's their function and are they supposed to be opened/drained from time to time? Mine are crumbling so I'll probably need to replace. There's also another plug on the inside of the front right fender, at the back of the fender that's missing (but in place on the left side). I notice I'm getting some wetness in the cabin, I assume that's the culprit? Thanks- Rob |

They are for draining paint during manufacturing.

floor pan drains
If the holes are directly in the floor these are drains in case of flooding , srping cleaning etc. If the holes are on actual frame these are refrence holes for frame tech to hang guages for frame repairs. Any drains in fenders are probally for drains from your cowl vent . Your cabin wettness could be anything from a leak in windshield to leak at firewall. Get friend flashlight and water hose out to detect were water is entering. Start a gentle flow of water at top of windshield and work slowely around while someone is inside close up searching for leak. After windshield check inside firewall inside engine compartment. Work this from one side to other. Also check drains from cowl vent area. ,and check drains from sunroof if u got 1 . Cowl vent drains and sunroof drains can be blasted with compressed air. Check inside sunroof are for these drains. If you don`t have a air compressor maybe a friendly shop near by would do this for u . Good luck and God bless P/s Auto body sealer for fire wall area and silcone sealer for small leaks in windshield.

thanks!
Thanks guys, this helps quite a bit. The wetness is in the front-right corner of the passenger wheel well...aka if you were a passenger in the car where your right foot would be. I left the car out in the rain last night and it seems to have gotten wetter; to me this suggests it's the windshield as I'd need some airflow from the moving car for water to get across anything in the firewall or inside fender... does that sound correct?
