That means **battery disconnected**, careful sequencing, and respect for every clip and connector hiding behind the headliner. while you’re in there—bundle the rest of the crash repairs (**seat-belt pretensioners** and **airbag control module reset**) in a single pass through **MyAirbags**. Two important truths up front: 1. **Curtain airbags are not repaired**—they’re replaced with new OEM units. 2. **MyAirbags does repair/reset** the *supporting* SRS components (seat belts & the airbag control module), which is why this removal is often done alongside an **SRS module reset** and **belt rebuild**. **Need crash-data cleared or locked belts rebuilt? [Start an Airbag Module Reset](https://www.myairbags.com/repair-reset-srs-airbag-control-module/?utm_medium=organic_social&utm_source=blog&utm_campaign=blog_post_series&utm_content=https://www.myairbags.com/repair-reset-srs-airbag-control-module/M3-roofairbags-CTA1)** # Safety first (non-negotiable) - **Disconnect the battery** and wait several minutes before touching any SRS connector. - **Never probe SRS connectors** with power connected. - **Do not ship live airbags.** Replace curtain airbags locally with OEM parts; ship only belts/modules for service.   # Tools you’ll actually use (from the video walkthrough) - Torx: **T15, T25, T30** - **Drill/driver** with Torx bits (optional, speeds things up) - **Clip remover** / plastic trim tools - **Needle-nose pliers** (two help) - **Pick tool** - **Flathead** screwdriver - Painter’s tape & labeled bags for hardware # Step-by-step: remove headliner & curtain airbag (G80 M3 shown) # 1) Drop the center overhead light - Pry down the **center light’s outer panel** with a clip tool; it’s held by small clips. - Remove **two T15 screws** under the cover. - At each corner of the light are **horizontal retaining clips**—push in and pull the assembly down. - Unplug the **four wiring connectors** (press each lock tab, pull straight out). ### 2) Remove both sun visors & related pieces - **Unclip the cosmetic covers** to expose the inner fasteners. - Use a flathead/clip tool in the **inner slot**; pull the visor down slightly. - Release the **metal clip set**: with a flathead/pick, squeeze both sides toward the middle, wiggle the visor arm free. - For the other anchor, push the hidden **retaining clip** down and remove. - Unplug the **visor electrical connector** and set the visor aside. - Pop out nearby **overhead light/microphone** modules the same way (clip tool, then unplug). ### 3) Remove the grab handles (front & rear) - Pop the **decor caps**: insert an angled tool into the slot, twist gently, pry the cover off. - Inside, use a thin flathead + needle-nose to compress the **silver spring clips** from both sides toward center; wiggle one end of the handle free, then the other. Repeat for rear handles. ### 4) Free the front and rear pillar trims - Front: pop the **“AIRBAG” emblem** with a clip tool; remove the hidden **T25** bolt. - Ease the **door weatherstrip** back to release the trim claws; rock/wiggle the A-pillar cover rearward until it unhooks. - Rear: similar move—peel the weatherstrip slightly, insert hands/clip tool from the top, tug the C-pillar trim free. Set both aside. ### 5) Drop the headliner carefully - At the **rear**, release **two headliner clips** with a firm downward tug. - At the **front**, release the remaining clips. - Around the **sunroof opening**, work evenly—there are clips along all four sides. - Support the headliner as it lowers so it doesn’t crease; rest it on protected seats. ### 6) Expose & release the curtain airbag - Unplug the **airbag connector** (lift lock, then pull straight out). - Along the roof edge are ~**six retaining clips** securing the curtain’s fabric tabs. - Best technique: two needle-nose pliers or a pliers + pick—compress the inner walls of the clip and wiggle out the tab without tearing the fabric. - Remove the **four T30 bolts** holding the inflator/module to the body. - Lift away the **curtain airbag**—it’s now free. > Notes: > > - Keep every bolt/clip bagged by step (e.g., “Step 6—T30 inflator bolts”). > - If the curtain has deployed, expect talc/residue—cover the interior and vacuum gently after removal. > - Replacement is the reverse with a new OEM curtain; torque to BMW spec (check your TIS). # Clean curtain removal, bundled SRS services A 2021 M3 arrived with a **driver-side curtain deployment** after a side swipe. The tech followed the sequence above to drop the liner without creases, removed the curtain, and—while open—pulled **two locked pretensioners** and the **SRS control module**. The curtain was replaced new (dealer part); belts and module went to **MyAirbags**. The belts were rebuilt with OEM-grade components, the **module crash-data reset** came back next day, and the car reassembled with no warning lights. One interior tear-down, all SRS faults resolved.

Any deployed or faulted curtain must be **replaced with an OEM unit** and installed to factory torque/position. What *is* serviceable are the components that commonly trigger the SRS light after a crash: - **Seat-belt pretensioners/webbing** — MyAirbags rebuilds pretensioners and can reweb belts with OEM-grade materials. - **Airbag control module** — MyAirbags **resets crash data** so you keep your original coding and configuration. Bundling these services during the same headliner drop saves time, shipping, and a second teardown. # Reinstall checklist (reverse order, but smarter) - **Mock-fit the new curtain**: clip tabs loosely first, then install **T30 bolts** and torque to spec; finish clipping the tabs evenly. - **Harness routing**: follow the original path and retainers; confirm no wire is pinched behind the headliner edge. - **Headliner up**: seat sunroof-edge clips evenly, then front, then rear. - **Pillar trims**: hook the feet, align, then push until the claws snap; reinstall weatherstrip lip. - **Grab handles & visors**: compress spring clips fully—listen for a solid “click”; don’t forget visor plugs. - **Overhead light**: plug all four connectors, seat the horizontal clips, reinstall **T15** screws and cover. - **Battery reconnect & scan**: after belts/module are back in, reconnect the battery, scan the SRS for codes, road-test for rattles.   # DIY owner, pro finish  A DIY M3 owner removed both curtains after a garage mishap triggered one side. He followed the photo-every-step approach, labeled all hardware, and avoided a cracked headliner by supporting it on towels. A dealer supplied both new curtains; **MyAirbags** handled two pretensioners and the **module reset**. Reassembly passed the SRS check on the first scan. The owner later said the biggest wins were “**two teardowns avoided**” and “**no broken clips**.” FAQs **Can MyAirbags repair my curtain airbag?** No. **Curtain airbags are replaced**, not repaired. MyAirbags repairs **seat belts** and **resets airbag modules** (crash-data), which are typically needed after a deployment. **Is battery disconnect really necessary?** Yes. Always disconnect and wait before touching SRS connectors/components. **What about shipping airbags?** Do **not** ship live airbags. Replace locally with OEM parts. You *can* ship seat belts and modules to MyAirbags (follow their packing/ground-shipping guidance). **How long are belt/module services?** Turnaround is typically fast once received; check MyAirbags’ service pages for current timelines. **Do I need coding after an airbag module reset?** In most cases, **no**—resetting and reinstalling your original module preserves vehicle coding. # Do it once safely, cleanly, and with the right division of labor A curtain airbag job lives or dies on **sequence**: battery off, lights/visors/handles/pillars, then headliner, *then* the airbag. Replace the curtain with a new OEM part; that’s the only safe path. But don’t miss the chance to **close the loop** on the rest of the SRS story while you’re in there: rebuild **locked pretensioners** and **reset the module** so the light stays off for the right reasons. That’s where **MyAirbags** shines—repair-and-return on belts and modules, OEM-grade results, and a workflow that lets you button up the interior **once** and get back to enjoying the car. **Ready to wrap this up?[Start your MyAirbags Module Reset.](https://www.myairbags.com/repair-reset-srs-airbag-control-module/?utm_medium=organic_social&utm_source=blog&utm_campaign=blog_post_series&utm_content=https://www.myairbags.com/repair-reset-srs-airbag-control-module/M3-roofairbags-CTA3)** Previous Post ###### [Seat Belt Locked After a Crash?
