Which partner module we need from your car
- 2011-2012 F-chassis: your CAS module
- 2013+ F-chassis: your FEM or BDC module
- At least one working key, every time
- The used donor DME itself
- The ISN is read from YOUR module and written to the donor — the donor is never simply "coded" blind
Clone path instead — when your original still reads
- If your ORIGINAL DME still powers up and reads, cloning is usually the cheaper, simpler job at $250 — see our BMW DME ECU clone service
- Cloning copies your original DME data (ISN, VIN, calibration, adaptations) onto the donor, so the CAS or FEM/BDC never has to come out of the car
- This $399 service exists for the opposite case: the original is dead, missing, or unreadable, so the ISN has to come from the CAS / FEM/BDC side instead
- Not sure which you need? Send the VIN plus photos of both DME labels and we route you before you ship anything
Will This Fix My Problem?
Honest answer: here's exactly what this service fixes — and what it doesn't.
Fixes:
- Used DME installed from eBay/salvage — engine cranks but won't start
- Donor DME ISN doesn't match your CAS/FEM/BDC
- P1614 / P1570 codes after a DME swap
- Failed engine — want to swap to a known-good used DME and have it work
- BMW dealer wants $800+ to program a used DME
Won't fix:
- Pre-CAS E-chassis cars (E36/E39/E46/E53/early E60) — see our EWS Delete service
- CAS4/CAS4+ ISN issues unrelated to a DME swap — see CAS Key Programming
- New DME from BMW (those come pre-coded by the dealer)
- M-DCT transmission ISN faults (separate service)
- Not the cheapest route when your ORIGINAL DME still reads — cloning it onto the donor is $250 and leaves the CAS/FEM/BDC in the car. See our BMW DME ECU clone service (MS41-MS45, ME7.2/ME9, MSV70/80/90, MSD80/81/85/87, MEVD17.2.x, MG1CS003, plus MINI)
- A failed CAS1/CAS2/CAS3/CAS3+ or EWS3 module itself — that is our BMW CAS / EWS3 module clone service
- A dead, burnt, or no-comms donor that will not respond on the bench — that is our ECU advanced recovery service
- Proof of ownership is required, since reading an ISN is immobilizer work
Before you order
You diagnose, we service the module.
We don't have your car and we don't diagnose it. Order once you or your mechanic have confirmed this module is the cause. If the work is completed and the car still has the same symptom because of another fault, the work is still done — a bench re-test under warranty is free.
A clone copies what is in your module.
We transfer the data as we read it. If another shop or tool already worked on the module — an unfinished clone, a tune, a delete — that data can come across too. Tell us before you ship.
What "plug-and-play" means.
No dealer programming should be needed when your original data is intact, the donor matches your module (same type, hardware and software family) and the rest of the car works. It isn't a promise that the car will start or run.
Why we need BOTH the DME and the CAS/FEM/BDC
The MEVD172 DME family stores an ISN (Individual Serial Number) that must match the ISN stored in the vehicle's CAS (pre-2013) or FEM/BDC (2013+). On an F-chassis BMW, we can't just write any ISN to the DME — we have to READ your specific CAS/FEM/BDC's stored ISN first, then write it to the donor DME. That's why we need both modules shipped together. After we're done, both modules go back to you and reinstall plug-and-play. There is one case where you do NOT need to pull the CAS/FEM/BDC at all: if your original DME still powers up and reads, we can clone it straight onto the donor — ISN, VIN, calibration and adaptations included — for $250 under our BMW DME ECU clone service, and only the two DMEs travel. This $399 service is the answer when the original is dead, missing, or unreadable and the ISN has to come from the vehicle side instead.
