I went to a recommended Porsche tech center and I got the younger tech (no one else was there when I arrived). I don't know if I learned as much as I could have otherwise.

I bought a 2.7 (2001 year) and have been working through several little problems, but one of the big remaining problems is both speedometers, the odometer and the spoiler do not work.

The young tech hooked it up to his "better than Durametric" scanner and reset the codes but told me they would probably come back.

I asked him how to find the speedometer problem and he said it would cost him more money (time) to find it than I would pay him. He then told me (rightly) that I still needed to fix it.

He said it could be the speed sensors (but he didn't seem to know which one feeds the speedos (or maybe I don't understand and all of them feed the speedos).

He said it could be the ABS controller (but said it was expensive) (My gut tells me this is the problem as I checked continuity on the sensors.)

He said there was also an indication of a "Can Bus" error even the Air Conditioner not getting info to/from the Can Bus.

He said it could be the entire instrument cluster (everything else seems to be working properly).

On the way home the Check Engine Light did come back on like he predicted.

He was a nice guy and helpful (to a point) so I don't want to sound too sour about still leaving me with a lingering question. ( I drove it almost 1.5 hours to get this figured out but came home with it still there.)

Any ideas or recommendations are welcome!!!
