Thanks for first ideas.

@Stl-986

Sounds like the key/dme/immobilizer aren't matched up

This was my first idea also.
To check this, I removed the transponder from the key.
Then immobilizer throws error "wrong key or key not matched" and cant be cleared
When puting transponder back into the key, error is gone, respectively can be cleared.
So I hope this should be OK, but not fur sure of course.

1 thing would be to find someone close to you that you can take the combo from your car and put in theirs to see if it still starts, or do the opposite.

Would be a great idea if I had someone with the same car nearby.
But unfortunately I haven't.

Not sure how you (or if you had someone do it) "cloned" things over. This isn't a simple thing to do with these cars.

That's my daily business. ;-)
Not for Porsche´s, but for VAG group (VW, Audi, Seat and Skoda) and you're right, Porsche seems to be a little different.
I have all the tools (and 20 years experience) to extract and read/write the memorychips of most ECU's.

@thstone

Are you sure that the ECU, immobilizer, and the key fob transmitter are all programmed with the same code?

Not 100% for sure, but because no error is stored in immobilizer (except I remove the transponder from the key) I think (hope) this should be OK.

Any other ideas ?
