DME Repair & Return Service – MOSFET Failure Repair
This is a repair and return service for your existing DME.
By purchasing this service, you agree to send us your DME for repair—this is not a sale of a new or replacement unit.
Service Details:
We repair DMEs suffering from MOSFET-related failures that trigger the following fault codes:
* 30BA – DME Digital Motor Electronics, Internal Failure
30BB – DME Digital Motor Electronics, Internal Failure
29CD – Cylinder 1 Misfire
29CE – Cylinder 2 Misfire
29CF – Cylinder 3 Misfire
29D0 – Cylinder 4 Misfire
29D1 – Cylinder 5 Misfire
29D2 – Cylinder 6 Misfire
29CC – Misfire Multiple Cylinders
During the repair, all six MOSFETs will be replaced.
This service addresses only the above-listed fault codes and may not resolve unrelated DME issues.
After Repair:
No reprogramming is required—your DME will be plug-and-play.
Clear all stored fault codes before use.
Inspect ignition coils and fuel injectors before reinstalling the DME, as faulty components can cause repeat failure.
THIS IS NOT A PART FOR SALE. IT IS A REPAIR SERVICE
