MSD80 Mosfet Repair

The MSD80 DME is known for MOSFET failures that cause no-start conditions, misfires, and injector or ignition faults. Rather than replacing the entire unit, we perform component-level repair targeting the failed MOSFET(s) directly. This restores full DME function at a fraction of the cost of a replacement unit. Compatible with the N54 engine platform found in the 135i, 335i, 535i, and Z4.
