What you get

  • Your original MED9 ECU's identity, immobilizer data, coding, and learned adaptations cloned onto your donor — immobilizer preserved, existing keys keep working
  • Or, on the immo-off path, the immobilizer requirement removed from the module so it runs on a standalone, orphaned, or swapped platform
  • Donor part-number compatibility verified against your VIN and both ECU labels BEFORE you buy or ship anything
  • A full bench read and verify pass of both units before a single byte is written
  • Checksum-correct write with a powered communication test on a stable, regulated bench supply before return
  • Plain install notes — what happens at first key-on, and which adaptations relearn on their own
  • Modules returned with tracking, at the return-shipping speed you select and pay for at checkout

Is there a vw/audi med9 ecu clone / immo-off shop in Sioux Falls I should use instead?
Most Sioux Falls shops don't keep the bench equipment for vw/audi med9 ecu clone / immo-off — 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 2-3 days each way.
Does South Dakota vehicle inspection or emissions testing affect this service?
South Dakota has no statewide periodic vehicle safety or emissions inspection program. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all South Dakota and federal requirements.
What is a MED9 ECU and which cars use it?
MED9 is the Bosch direct-injection engine controller VW Group used from roughly 2004 to 2010, sitting between the older ME7 and the newer MED17. You will find MED9.1, MED9.1.1, and MED9.5.10 on the VW Golf Mk5 and GTI 2.0 FSI / TFSI, Jetta Mk5, Passat B6, Eos, and Scirocco, and on the Audi A3 8P, A4 B7, A6 C6, and TT Mk2, plus the Škoda Octavia II and SEAT Leon Mk2 cousins. The variant is printed on the ECU label.
Why won't a used MED9 ECU just work when I plug it in?
Because the immobilizer relationship is stored inside the ECU and still belongs to the donor car. When you install it, the module and your car's immobilizer system fail to agree, so the engine cranks and cranks without firing — often with an immobilizer warning or a stored P1570. Cloning copies your original's identity onto the donor so the mismatch never happens; immo-off removes the requirement entirely on builds with no key system left to satisfy.
