Critical Compatibility & Programming Notice:
  • ✅ This TCU is for vehicles originally equipped with **factory telematics** (look for “ConnectedDrive” in iDrive).
  • ⚠️ Programming & Coding Required! The module must be:
    • Paired to your vehicle’s VIN
    • Activated via dealer or professional tool (e.g., ISTA, E-SYS, Autel)
    • Linked to your BMW account for remote features
  • Match your original part number exactly. Even small suffix differences (e.g., -CA vs -CB) may affect compatibility.
  • If unsure, send your VIN + photo of current TCU label before ordering.
⚠️ Condition & Limitations:
  • This is a pre-owned unit—tested for power-on and basic communication only.
  • May not support newer ConnectedDrive services if original carrier network (e.g., AT&T 3G) has been sunset.
  • No warranty on functionality after installation—professional verification recommended.
