Post-Reset Requirements
After module reset and reinstallation:
- Clear any remaining DTCs using manufacturer scan tool

- Verify all sensors and components communicate correctly
- Road test to confirm airbag light remains off
- Some vehicles may require steering angle sensor calibration
Frequently Asked Questions
Is this service compatible with all Porsche vehicles?
This service is specific to the 99761821705 module. Porsche uses different module part numbers across their range, so it's essential to verify your exact part number matches before ordering.
What if my module has a different revision code?
Minor revision codes (like -M1, -M2, -A, -B suffixes) are usually compatible. Send us a photo of your module label if you're unsure - we can confirm compatibility before you order.
How do I know if crash data is my problem?
If your airbag light came on after a collision (even minor) and won't clear with a scan tool, crash data is likely stored. A diagnostic scan showing B1015, B1000 codes often indicates crash data presence.
Do you offer mobile service in my area?
No, this is a postal service only. However, many customers find it more convenient than mobile services - you can remove the module yourself (usually 4-6 bolts) and have it back within 1-2 days via Royal Mail.
