Automotive Electrical System — Replacement Actuators, Sensors, Valves and Motors for Mercedes-Benz and BMW
The electrical system covers the body and safety electronics that lock the doors, monitor wheel speed and operate cabin and wiper functions. VOLLSUN supplies replacement electrical components for Mercedes-Benz and BMW applications, matched to the original equipment references.
The VOLLSUN electrical range is organised into two groups:
- **Door Lock Actuators** (7 references) — front and rear door lock actuators, including V18501 (OE 51217148475), V18513 (OE 51217202143) and V18515 (OE 51227202147).
- **Sensors, Valves & Motors** (9 references) — ABS and wheel speed sensors, heater control valves and wiper motors, including V69004 (OE 2049052905), V21502 (OE 64116910544) and V21517 (OE 61617200510).
Each listing states the VOLLSUN SKU, the listed OE reference and the recorded vehicle applications. Electrical parts are position- and platform-specific: for door locks confirm the door and side, and for ABS sensors confirm the axle position, against the removed component. After fitting a sensor, follow the vehicle diagnostic procedure; this page does not cover diagnostics or coding.
For braking electronics, see Brake Wear Sensors under Automotive Brake System. For other systems, browse Automotive Chassis System or Automotive Cooling System.
Frequently asked questions
- How do I choose front or rear, left or right? Compare the OE number and the position recorded on the removed unit; the listing states the application.
- Will the fault code clear after fitting? Follow the vehicle diagnostic procedure; this page does not cover diagnostics or coding.
- Do the photographs confirm fitment? No. Images support identification only and do not establish compatibility.
- How do I request supply information? Use the inquiry form with SKU, OE, quantity and destination for availability, price and packaging.
