Mercedes-Benz Airbag Module Reset — $75 flat
Mercedes-Benz calls it the Restraint Systems Control Unit (SRS control unit). After a deployment it locks its crash data — the light stays on and no scan tool clears it. We reset your original module on the bench, 24–48 hours, plug-and-play on return.
Mercedes-Benz dealer: new SRS control unit typically $350–$1,200 + programming + the wait for the part
Auto Module Lab: $75 flat — your original module, already matched to your Mercedes-Benz
What we reset on a Mercedes-Benz
Mercedes restraint control units latch the crash event and XENTRY will not release it. The bench reset clears your original unit — the path that avoids both the new-part price and the variant-coding step a replacement needs.
Where it lives: under the center console / on the transmission tunnel. Disconnect the battery, wait 10+ minutes, photograph the connectors, unbolt and ship just the module.

Mercedes-Benz reset questions
Is a reset safe? Will the airbags still work?
A reset returns the module to its pre-crash state — the same state it shipped in before the deployment. It does not alter the deployment logic. After reinstalling, the system self-tests on every key cycle exactly as designed. If we find internal damage that a reset can't make right, we tell you and refund instead of shipping back a module we wouldn't put in our own car.
Why not just buy a used SRS control unit?
Used Mercedes-Benz modules usually carry the donor car's coding — and on many platforms they're VIN-married, so the car rejects them or needs dealer programming. Your original module is already matched to your vehicle; clearing it keeps everything plug-and-play.
How much does the dealer charge instead?
A new module is typically $350–$1,200 in parts depending on the Mercedes-Benz model, plus installation and programming labor. Our bench reset of your original is a flat $75, with 24–48 hour bench turnaround.
Where is the SRS control unit on my Mercedes-Benz?
Typically under the center console / on the transmission tunnel. Disconnect the battery and wait 10+ minutes before unplugging it, photograph the connectors, and ship just the module — see the packing instructions in your confirmation email.
