W123/300td: Water collecting in spare tire well - Sources?
 

Hello - I'm geting water collecting in the spare tire well after heavy rain - any ideas as to likely sources - Where does the sunroof drain at the rear & how - I can't see any drainage holes underneath & I'm suspecting it's leaking internally & ending up in the spare wheel well.

most likely
 

from the rear window gasket. it can be replaced or caulked with (i use black silicone). some here dont like silicone, but i have had good luck with it for about 15 years so far.

sometimes i have found even a new gasket needs caulking.

Tom - do you mean the tailgate window or the rear side windows?
