VW Eurovan Transmission reset procedure...

This was required after the "re-wiring" of my melted wiring harness going to the transmission.

Subject: Resetting the Eurovan Adaptive Transmission Sequencing

The Eurovan uses an electronically controlled transmission which sets shifting points based upon engine load and RPM information that is "learned"
from your specific driving habits. 

This information, which is stored in the transmission's electronic control unit, can sometimes become garbled and may need to be reset to the
default pattern,so that it will "re-learn" your driving style.

In order to perform this reset, do the following:

1. Turn on the ignition, without starting the engine.

2. Turn the ignition back to the off position.

3. Turn ignition on again without starting the engine and depress the accelerator all the way to the floor, holding the pedal there for a 
minimum of ten seconds.

4. Release the accelerator pedal and then start the engine in the regular manner.

5. Drive the vehicle making sure that the transmission shifts through all four gears.

  1. 4) "...then start the engine in the regular manner." Does that mean the ignition switch should again be turned off and then started "in the regular manner" or just started from the current 'on' position (does it matter)?

  2. I don't think it matters, but try both. If you are noticing weird shifting, EV has been in limp mode, or work has been performed, this doesn't hurt anything. Just resets.
