Mercedes diesel IMMO Off — frequently asked questions

Can you turn off the immobilizer on a Mercedes diesel ECU?

Yes. Karman Auto performs IMMO Off on every Mercedes diesel ECU built from 1996 through current — Bosch EDC15, EDC16, EDC17, MD1CP002, Delphi CRD2/CRD3. OM611, OM612, OM613, OM642, OM651, OM656, plus Sprinter and Vito. We have been doing bench-level Mercedes diesel work since 1999 — 27 years, longer than any active US Mercedes diesel IMMO service. BBB A+ accredited.

What does Mercedes diesel ECU IMMO Off actually do?

We modify the ECU’s flash to bypass the immobilizer handshake with the EIS/EZS ignition module. After IMMO Off, the ECU starts and runs without needing the EIS or any key pairing — perfect for used-ECU swaps, project cars, or vehicles where the EIS is also failed. We do this bench-level so no dealer XENTRY step is required.

Is the Mercedes diesel IMMO Off process permanent?

Yes. The IMMO Off is written into the ECU flash permanently. The ECU stays IMMO-disabled until you flash it again with a different file. The car runs forever in IMMO Off state — no warning lights, no time bombs. 27 years of writing diesel IMMO Off flashes means we have refined this to be invisible.

How long does Mercedes diesel ECU IMMO Off take?

Typical bench turnaround is 24-48 hours from when we receive the ECU. We ship back USPS Priority the same day work is complete. Most customers see the IMMO Off ECU back in 5-7 days door to door. 27 years of refining this exact process.

Do I need to send the keys with my Mercedes diesel ECU for IMMO Off?

No. We do not need any keys. The whole point of IMMO Off is to bypass the immobilizer handshake entirely — there is no key data being read, written, or paired. Send only the ECU. 27 years of doing this work bench-only.

Will my Mercedes diesel start without the EIS or original keys after IMMO Off?

Yes. That is exactly what IMMO Off enables. After our work the ECU no longer waits for an EIS handshake to start. You can run the car with a generic ignition switch, a button start swap, a stolen-recovered vehicle missing the EIS, or a used ECU where the original key pairing is unknown.

Does Mercedes diesel IMMO Off require XENTRY, DAS, or SCN coding?

No. The whole point of bench IMMO Off is bypassing all dealer programming. Conventional immobilizer programming requires Mercedes XENTRY plus SCN online coding — dealer-only and slow. Karman Auto IMMO Off bypasses both. Install the ECU and the car starts.

Which Mercedes diesel platforms support IMMO Off?

We support every Mercedes diesel ECU platform: Bosch EDC15 (Sprinter T1N, early CDI), EDC16 (OM611/OM612/OM613/OM642), EDC17 (OM651, OM642 update, OM656), MD1CP002 (newest BlueTEC), Delphi CRD2/CRD3 (Sprinter NCV3).

Will IMMO Off affect the engine running quality, emissions, or DPF function?

No. IMMO Off modifies only the immobilizer handshake portion of the ECU flash. Fuel maps, timing, boost, AdBlue/DEF, EGR, and DPF logic stay untouched. The car drives, idles, and meets emissions exactly as it did before. 27 years of writing IMMO Off without touching engine calibration.

Can I send a used Mercedes diesel ECU for IMMO Off?

Yes — and this is one of the most common uses for our service. Buy a used ECU from a salvage yard, send it to us for IMMO Off, install it in your car. The ECU starts without needing to match your EIS or keys. 27 years of helping customers recover from no-start situations with used ECUs.

Will the odometer reading change after Mercedes diesel IMMO Off?

No. We modify only the immobilizer flash section. Mileage data stays untouched. Karman Auto does not roll back or alter mileage under any circumstance — same policy since 1999.

Is Mercedes diesel ECU IMMO Off legal?

In the United States, IMMO Off is legal for off-road vehicles, project cars, racing applications, and pre-1996 on-road vehicles. For post-1996 on-road use, IMMO Off may not comply with anti-theft requirements in some states — consult local regulations. We have operated under BBB A+ accreditation for 17 years.
