I'm taking my car in for an alignment and doing some research on various new racks looks like they are now including a steering angle reset as the new "last step" of the whole process. I know this is possible to do with VAG-COM, but is it 100% necessary. My dealership says it is only necessary if the light comes on and there is a problem with the sensor itself. I've also heard that not resetting it can cause the steering wheel to be off center, as it is now. Give me some opinions please. Thanks!
