Ask in Honda, not VW

Best use the Honda forum, a description like weird knock needs more illumination. Where is the knock coming from left right side, engine compartment, trunk, when you turn left or right, going over a hill, bump, when you first start your car or after a bit.

Hint, if it is knowcking when you first get in the car and it is from the trunk area, then open the trunk and let the squirrels out.
