Genuine BMW factory high-performance master engine management DME computer unit. If your V10 M-car has suffered an internal electrical processor short circuit, permanently drops communication with diagnostic scanners, or triggers unresolvable internal RAM/ROM check faults, this original Siemens VDO replacement controller will restore your powertrain line.

The unit (Part No: 7 841 201 / Siemens Model: 5WK93911 / Designation: DME MS S65 / Index: 10) is in excellent used condition with a perfectly flat, clean aluminum structural heat dissipation housing casing, pristine factory perimeter sealing, and zero bent or oxidized terminal pins inside both main high-density wiring block bulkheads.

Fitment note: Sourced from an original factory S85 V10 configuration. Please cross-reference your specific original part number (7841201) to confirm a direct component matchup.

⚠️ Important Installer Note: Like all modern BMW high-performance engine computers, this DME is strictly locked down with individual vehicle Rolling ISN security synchronization codes. It will require professional bench-cloning (transferring data from your old unit to this one) or a complete CAS-Immobilizer alignment to match your original car keys and pair with the chassis configuration before the engine will crank.

Warranty: 1 month warranty covering core hardware processor stability, sensor supply voltage rails, and main CAN-bus transceiver communications.
