    UPDATE:
    Tried procedure 3 full sequences... (3 times of 3 times each...) and still there... and wont even try to crank.....

    saw a earlier post if there is no keylock symbol on dash then ECM is bad... but I do have the keylock symbol......

    so no luck so far!!!!!!

    going to check all the fuses and starter wiring.. but still has the darn p0633 code....

    Stupid question but ....Did the dealer put the correct vin in the ECM ?? For some reason it sounds like the modules
    are communicated with each other.

    I still think its the security relearn thing. I dunno if that backyard procedure actually works though.

    It does, I did it on my car. Post 71 in my aps TT Install thread has a link to how I did it. It's a bitch and it has to be exact. If I remember right I made sure every thing was off and reached through the drivers side window to make sure nothing else electrical happens on the car

    We did it exactly like your posting..... but still no go... may try again...
    but what does the phrase in the instruction mean "the procedure will not learn the immobilzer prerelease password or the challenge/response data".... how does it get to do those things?... anything special have to be done?..... hmmmmm

    do you know is there a way to check with HP tuners if the VIN number was put in correctly????.... or do I need a dealer to do that?.... my dealer seems to not be able to do anything with the ECM alone... they need it in the car.....

    I wonder if I can get a loaner or something from someone like Vector to see if it is a ECM issue or some other wiring issue.... I will call them in the morning... trying to move the car back to the dealer is a real pita....
