It IS testing bad as the N.O. contact is NOT closing as it should no matter what voltage on relay coil is applied (Spec is 5 VDC).

Mechanical always fails before electrical

I am going to make a full diagnostic step-by-step on the 986 immobilizer soon, as i've really beat this thing up and it keeps working....mainly I feel it's unfair for local repair places to be charging owners 1100 to 1500 for a short operation to re-teach a new immobilizer. The part is only around $400 from porsche, so no repair in my opinion should be more than 500 dollars.

Good I am looking forward to this.
