Some newer BMW models have a flaw where the sunroof seal shrinks and leaves a gap where water and debris can enter the drain channels and clog the drain tubes. A clogged sunroof drain can lead to thousands of dollars in damage when the water seeps into the car.
The TPU Gap Filler offers a temporary or permanent solution to fill the gap left by the shrinking sunroof gasket and offers the following benefits:
- Prevents large debris and dust from entering the sunroof drain system
- Prevents large amounts of water from entering the sunroof drain system
- Eliminates wind noise left by the gap
- Fills the gap to avoid visual eyesore.
The TPU Gap Filler is 3D printed using shore hardness of 95A. TPU is UV and weather resistant.

Installation
Avoid removing the seal from the sunroof as it may be hard to re-install correctly. Instead, you can do the following:
- Chose the right size Gap Filler - Slightly longer is better
- Push the whole seal back with your fingers, it'll move along the track. Spraying a small amount of silicone lubricant can help.
- Insert the Gap Filler on the glass. Use a plastic trim tool
- Pull seal back onto the Gap Filler until it sits flush.
