How do Mercedes Benz EIS Mail-in Repairs Work?

The ECU Pro offers a convenient mail-in Mercedes-Benz Electronic Ignition Switch (EIS) repair service. Simply remove the unit from your vehicle and mail it to our facility along with your ECU and key, after which we will conduct diagnostics, perform repairs, or replace your unit as necessary.

To get your Mercedes-Benz EIS repaired, tested, or replaced, follow these easy steps:

  1. Mail your current EIS, ECU and KEY to our repair center.
  2. We will conduct a comprehensive diagnostic test on your EIS and provide you with a detailed report.
  3. Based on the diagnostics, we will suggest a repair or replacement. You can then decide on the course of action you prefer.

Our mail-in repair services are designed to be 100% plug-and-play, meaning that once you receive your repaired unit, you can simply reinsert it without any additional coding or programming required.
