Oh heck, I did that and now the Touareg won start. What do I do now?
• Use your VAG-COM to clear the “Crash Data” code from address 05 or 25. • Reset the yellow battery isolation switch under driver’s seat. This is switch is visible/accessible if you remove the carpeted “step” trim panel at the front of the seat (an operation requiring some dexterity, but no tools).
