EWS delete by ECU type
Postal immobiliser / EWS delete service for MS45.0 ECU hardware. This listing is selected by ECU family rather than vehicle model. General engine reference: M54; confirm MS45.0 from the ECU label.
This is a service on your ECU, not the purchase of a replacement unit. Please confirm the complete ECU label and requirements before ordering. A vehicle model or engine code alone is not enough to select the correct service.
How the postal service works
- Send a clear ECU-label photo if you need us to confirm the family, hardware and service suitability.
- Place your order after compatibility is confirmed.
- Package your ECU securely and include your order number, name, contact telephone number, engine/chassis details and any modifications.
- Send it to Digital Tuning Solutions, REF: ECU Services, Unit 7 Terrace Factory, Rossfield Road, Ellesmere Port, CH65 3BS, United Kingdom.
Contact us before sending an ECU from outside the UK. Use accurate customs information; import or other charges may apply. Delivery charges are shown at checkout.
