BMW MSD80 & MSD81 30BA 30BB MOSFET Upgrade / Repair

We specialize in repairing MSD80 and MSD81 units using original MSD81 MOSFETs for the highest quality and reliability. This service specifically addresses MOSFET failure and does not repair other non-MOSFET-related misfire issues. During the repair process, all six MOSFETs are replaced to ensure optimal performance, even if only some are faulty. If the MOSFETs do not need to be replaced, we will notify you.

MOSFET failure is commonly associated with the following DTC codes:

• 30BA / 30BB: Internal Fault
• 29D0 / 29D1 / 29D2: Cylinder Misfire
• 29CC / 29CD / 29CE / 29CF: Cylinder Misfire Codes
