61.35 6944840 / 61356944840 / 6944840 / 57762110 Body Control Module BCM BMW X3.
This Body Control Module (BCM / Basic Module 5 / GM5, etc.) bearing part numbers 61.35-6-944-840, 61356944840, 6944840, and 57762110 is an OEM electronic module used in BMW vehicles (notably X3, 3 Series, etc.). The BCM controls and monitors multiple body and comfort functions such as lighting circuits, central locking, interior convenience systems, indicator/hazard warning, footwell control, and certain CAN bus message routing.
When replacing or sourcing a BCM, it is critical to match not just the part number but also hardware (HW) and software (SW) versions, coding, and configuration. Many replacement modules must be coded, adapted, or programmed to the vehicle to correctly integrate with existing wiring, features, and key / chassis data. Modules may be supplied in used / refurbished condition and should be tested for functionality before shipping.
| Vehicle / Application | Notes / Model Years | OEM Part Numbers / Identifiers | Remarks / Cautions |
|---|---|---|---|
| BMW X3 (E83 generation) | ~2004–2010 | 61.35-6-944-840 / 61356944840 / 6944840 | Common BCM part used on X3 models. Many listings for “BCM 6944840” specify X3. |
| BMW 3 Series / E46 / related | ~1999–2006 | 61356944840 / 61-35-6-944-840 | The same BCM hardware is often used across 3 Series / X3 cross-applications. For example, eBay listings advertise BCM 6944840 for 3 Series / X3. |
| Other BMW models | — | 57762110 | Might be internal or alternate identifier / variant; check compatibility carefully |
Important Considerations:
Even when the BCM has the correct part number, the internal software version, feature coding (e.g. ambient lighting, convenience features), or region variant (e.g. Europe / US / Asia) may differ and require correct adaptation.
The module must be coded / programmed to your car’s VIN and car feature set using BMW coding tools (e.g. ISTA, NCS, Winkfp).
Always verify pinout / connector type, and request photos or pin configuration from the supplier.
Used or refurbished modules should be tested for electrical continuity and signals before installation.
Retain your old module if possible to back up coding data for reference.
