What you get

  • Your original Simos ECU's identity, immobilizer data, coding, and learned adaptations cloned onto your donor — immobilizer fully 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 ECU labels BEFORE you ship or buy 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 whether any relearn or adaptation applies at the car
  • Modules returned with tracking, at the return-shipping speed you select and pay for at checkout

Is there a vw/audi simos ecu clone / immo-off shop in Seattle I should use instead?

Does Washington vehicle inspection or emissions testing affect this service?
Washington discontinued its emissions testing program in 2020 and has no statewide periodic safety inspection. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all Washington and federal requirements.
What is a Simos ECU, and how do I know I have one?
Simos is the Continental (formerly Siemens VDO) petrol engine-control family VW Group ran alongside Bosch from roughly 2000 through 2020. The family name and part number are printed on the ECU label — you will see something like Simos 8.5 or Simos 18.1 on the sticker or etched into the housing. Send us a photo of that label plus your VIN and we confirm the exact generation and the service path before you ship or buy a donor.
Why won't a used Simos 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 the vehicle's immobilizer system fail to agree, so the engine cranks and cranks without ever firing — often with an immobilizer-active 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 that have no key system to satisfy.
