EWS delete by ECU type

Postal immobiliser / EWS delete service for MS40.1 ECU hardware. This listing is selected by ECU family rather than vehicle model. General engine reference: M50B20.

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

1. Send a clear ECU-label photo if you need us to confirm the family, hardware and service suitability.
2. Place your order after compatibility is confirmed.
3. Package your ECU securely and include your order number, name, contact telephone number, engine/chassis details and any modifications.
4. 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.

ECU identification

We need the full manufacturer part number and a clear photograph of the label. No complete verified part-number list has been supplied for this family yet; contact us if you are unsure. Hardware condition and programming version can affect the work available.

Check compatibility with Digital Tuning Solutions or call 01244 710374.

Original engine and chassis applications

Search ECU services by part number, engine and chassis.

Use this as an identification guide for the applications below. Market, build date, gearbox and ECU version still need to match; engine conversions must be checked against the installed hardware.

• M50B20TU: E34, E36. VANOS 2.0-litre applications; confirm the Siemens label. Existing conversions may use different hardware.

Check MS40.1 on the ECU. Do not select a Bosch M50 unit by engine capacity alone.

Find the ECU and read its label before ordering.
