Compatibility
Confirm your part matches one of the variants below before ordering. Not sure? Text us a photo and we'll verify.
Siemens DMEs
- MS41 — M52 inline six (E36 328i, E39 528i, Z3 2.8)
- MS42 — M52TU double-VANOS (E46 323i/328i, E39 528i, Z3)
- MS43 — M54 (E46 325i/330i, E39 525i/530i, E53 X5 3.0i, Z4 E85)
- MS45
- MS45.0
- MS45.1 — later M54 and N46 four-cylinder applications
Bosch ME variants
- ME 5.2 — M62 V8 (E38 740i, E39 540i)
- ME 7.2 — M62TU / N62 V8 (E39 540i, E38 740i, E53 X5 4.4i/4.6is, E65 745i)
- ME 9.2 — later N62 V8 (E60 545i/550i, E63/E64 645i/650i, E65/E66 750i)
M-Power DMEs
MSV / MSD families (later N52, N53, N54 units)
- MSV70 — N52 naturally aspirated inline six (E90/E91/E92 325i-330i, E60 525i/530i, E70 X5 3.0si, Z4 E85/E86)
- MSV80 / MSV81 — revised N52N (E90 LCI, E60 LCI, E83 X3, E89 Z4)
- MSD80 — N54 twin-turbo and N53 (E90/E92 335i, E60 535i, E82 135i, E71 X6 xDrive35i)
- MSD81 — later N54 / N53 hardware index
- These cars use CAS rather than EWS — the delete is done on the DME side, so the CAS can stay in the car or come out entirely
- Send the DME part number first: MSV/MSD units are verified individually before you ship
MINI (shared BMW DME architecture)
- EMS2 immobilizer delete — MINI Cooper and Cooper S, 2002-2006
- R50 hatch, R52 Convertible, R53 Cooper S supercharged (Tritec W10 / W11)
- Same bench workflow and the same $250 as the BMW units

Will This Fix My Problem?
Honest answer: here's exactly what this service fixes — and what it doesn't.
Fixes:
- EWS module failed, car no-start, dashboard "EWS" warning
- Used DME from another car — needs EWS sync removed to run
- Swapping engines and donor DME does not match recipient EWS
- EWS-related no-crank or crank-no-start
Won't fix:
- Mechanical engine failures unrelated to immobilizer
- Bad DME hardware (we program software, not repair the DME)
- CAS-equipped BMWs (2006+) — the CAS module itself is a different system: for a key, see our BMW CAS key programming service, and for a failed CAS or EWS3 module see our BMW CAS / EWS3 module clone. The DME-side immo-off on MSV70, MSV80/81 and MSD80/81 units IS done here.
- Does not clone your DME onto a donor with the immobilizer left intact — that is our BMW DME ECU clone service (ISN preserved, existing keys keep working)
- Does not adapt a used F-chassis DME to your CAS or FEM/BDC — that is our BMW F-series used-DME programming service
- Does not cover a dead, burnt, or no-comms DME that will not read at all — that is our ECU advanced recovery service
- Proof of ownership is required — immobilizer work is not done without it
EWS failed and a replacement EWS is hard to find?
BMW EWS modules are getting harder to source for older E36/E39/E46 cars. Instead of hunting a working EWS, ship the DME and we will permanently delete the EWS dependency in software. The car will start with any key in the ignition and no EWS module installed — a permanent fix that also makes the car much harder to steal-with-key-only.
Shipping Instructions
These details are also emailed to you the moment your payment clears.
We buy and email you a prepaid inbound label, so shipping it to us costs you nothing. Return shipping is selected and paid at checkout — Standard $29.95 (3–5 days), UPS 2-Day $54.95, or UPS overnight $94.95. Pull the DME from the engine bay (usually right side of the engine, two connectors), pack it padded, and ship.
