Where did you get that procedure from? It's quite a bit different to the one we've been using for many years.Can VCDS see it in the module list?
1. Key on (without starting it).
2. Hold gas pedal down to floor for 10 sec.
3. While holding gas, turn key off.
4. Let off of gas pedal.
5. Key on (do not start) for 5 min (for throttle readaptation). Touch nothing.
6. Start vehicle while touching nothing.
Right, but the Transmission is clearly in LIMP mode and I am getting a TCM communication error off the computer.That seems more like the gearshift switches are not being activated correctly.
Taking it in tomorrow to have them hook it up to their computers and try to figure it out. I just pulled back the carpet on the drivers side and checked all of the splices. Everything looks good with no water damage at all. So the harness looks solid on the drivers side. The TCMs (Transmission and T-Case) are both dry and look great. Replaced the stepper motor. Can't imagine what the problem is. I was working on the headlights right before this happened. Any possibility that something in the headlight harness might have caused this problem? I know that its a long shot but you never know...As I said, see if the module checks in with VCDS.
If the transmission is in limp mode, then replacing the module will do nothing.
Also did you remove connections and clean? I never seen a module just "burn out" unless contacted water.
I wish I could go to your mechanic, I have the exact same problem.Go the car back and we are back in business!!! They went through the harness and apparently replaced a couple dozen pins in the harness. Mainly in the cowl with the ECU and also under the shifter on the tranny tunnel. Car is back to normal and now I can tackle the rest of the issues.
