What you get

  • Your original CDI ECM's identity, immobilizer relationship, and calibration cloned onto the donor, where the original still reads
  • Donor part-number compatibility verified against your VIN and both module labels before you ship anything
  • Bench read and verification of both units before a single byte is written to the donor
  • Bench communication test on a stable, regulated power supply before the module goes back in the box
  • Clear install notes — what to expect at first key-on, and when a shop-side adaptation or relearn still applies
  • A straight answer up front if your original is too far gone to clone, with the recovery path explained instead of a surprise
  • Modules returned with tracking — return-shipping speed is your choice at checkout

Is there a sprinter / mercedes cdi ecm clone shop in Chicago I should use instead?
Most Chicago shops don't keep the bench equipment for sprinter / mercedes cdi ecm clone — they'd forward the module to a specialist anyway, which adds a markup and a middleman. Going direct to us is usually faster and cheaper. Cross-region north — about 2 days each way.
Does Illinois vehicle inspection or emissions testing affect this service?
Illinois requires emissions testing in the Chicago and Metro-East St. Louis areas; downstate counties are exempt. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all Illinois and federal requirements.
Why won't a used Sprinter engine computer just work when I plug it in?
Because the engine ECM is paired to the van's EIS/SKREEM/WSP through drive authorization. A donor unit still carries the identity of the van it came out of, so your engine turns over normally but never fires and the scan tool may report an immobilizer or drive-authorization fault. Cloning copies your original's identity, immobilizer relationship, and calibration onto the donor so it behaves exactly like the module that left.
Which controllers and engines does this actually cover?
The Bosch CDI diesel families: CR3.42 on 2003–2006 Dodge, Freightliner, and Mercedes Sprinter T1N 2.7L (OM647 / OM612); CR3.43 on 2005–2006 Mercedes E320 CDI (OM648) and related passenger diesels; earlier CR2.x on 2002–2003 Sprinter 2.7L; and related CDI controllers across OM611, OM612, OM613, OM642, OM646, OM647, and OM648. That spans Sprinter T1N and NCV3/W906, E-Class W211, ML W163/W164, R-Class W251, GL X164, S-Class, and the Jeep Grand Cherokee 3.0 CRD.
