Yeah then failing that you will have to disconnect the immobiliser.

And bridge the immobilsed circuit, which is usually the starter motor circuit in the steering column (thickish black wire with red stripe.)

Once I tried to start my car just and as I did the immobiliser re-armed and it wouldn't start. All the electrics had cut out and I had to disconnect and reconnect the battery. It was fine after that.

When you said everything comes on, does the dash light turns on too?

If it doesn't, then yes, its the immobiliser.

Is yours a tiptronic?

If yes, try with N, instead of P.


Else, it might be the starter motor.


PS: I had all these issues, and fixed them up, one by one. Except the P and N issue.
