Description
Need help finding your ECU or reading its label? Use our BMW ECU location guide.
Check the ECU before choosing a service
Send us the complete ECU-label photo, engine and chassis details, gearbox type and the fault or work required. Engine / system reference: M67 V8 master / slave system.
This is a compatibility enquiry, not a paid EWS delete service. We will confirm whether immobiliser removal is applicable, whether we support your exact hardware and what the work will cost before you order or send anything. No EWS-delete availability is promised for an unverified ECU variant.
Bosch master / slave references: 0281001843, 0281001844.
Master / slave assignment and service suitability must be checked individually. These are not M57 DDE 4.0 units.
Send your ECU details 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.
- M67D39: E38. 740d V8 with master/slave ECU system.
Compatibility enquiry. Confirm both labels and the required work; do not assume one M57 service covers a V8 ECU pair.
