How to use CGDI BMW to read/ write BMW N13/N20 and N55 ISN

How to use CGDI prog BMW MSV80 to read/ write BMW N13, N20 and N55 ISN without unsoldering?
Here share a real story from a customer. Hope can help you out.

Background:

A customer lost his all BMW car keys. He let a locksmith program a new key to his car. The locksmith made a small incision in the engine to program new keys. But the locksmith forgot to seal the incision when he finished all the work.

The car owner washed his car and caused water get into the DME. He asked BMW dealer whether the car has warranty when repaired outside. The BMW dealer told him cannot. Finally, the car owner changed a new ECU in the BMW store, but the BMW dealer didn’t find the incision so that compensated 30,000 RMB to the car owner.
So! Is there a fast and safe method to read BMW ISN without unsoldering or punching?
Of course! Here I’d like to share the method with wiring harness.
It’s very easy to use, only need to unplug the port from the car and connect the harness with DME.
