About EWS / CAS files

EWS and CAS dumps cover BMW and Mini immobilizer and car access modules. They are used for key programming, synchronising a replacement EWS or CAS unit with the engine ECU, repairing a module that no longer accepts keys, and recovering units after a failed programming attempt. Each dump is listed by module part number and processor type so you can match it exactly. Write it with a bench programmer, then finish the key work with a BMW key programmer. Secure payment and instant download; request any part number not listed.

EWS / CAS files: frequently asked questions

Can I sync a used CAS or EWS module with my car?
Yes. Write the dump that matches your module part number, then align the module to the DME/DDE with a BMW key programmer or the dealer tool. Dumps are supplied as read from working units and include the key data structure required for synchronisation.
How do I know that a file matches my ECU?
Compare the hardware number and software number printed on the ECU label (or read by your tool) with the numbers in the product title and attributes. They must match exactly; a different software version is a different file. If you are not sure, send us the numbers and a photo of the label before buying.
How is the file delivered?
Immediately after payment the file appears in your account under Downloads and a link is sent by e-mail. The file stays in your account, so you can download it again later. Files are delivered as ZIP archives containing the read exactly as it came from the unit.
The file I need is not listed. Can you supply it?
Yes. Use the file request form or e-mail us the vehicle, ECU model, hardware and software numbers. Most requests are sourced within a few hours, and the file is then added to the shop for you to purchase and download.
