Most of the door sills on the mid 2000 BMW models are subject to the rubber trim rotting and disintegrating. The rest of the part is still in good shape and replacements are getting expensive, particularly for the M and M Sport models.
I decided to see how well I could repair it with some self adhesive rubber trim. Here’s what I did:
1.Removed the trim panels using a plastic pry tool. There are 6 clips per panel.
2. Removed the loose rubber trim from the entire surrounding sill
3. Used a guitar pick to scrape away remaining trim from the panel
4. Clean mating surface with 90% ipa
5. Installed trim on lower part carefully following the curve and applying pressure
6. Apply trim to the upper part mitering where the 2 pieces meet
7. Used a toothpick to apply CA glue to the miters of the upper and lower and any areas of the curve that were sticking up
8. Clean the underneath of the door sill and reinstall
I’m pretty satisfied with the results. Total cost is under $9 vs around $250 for replacement sills.
