Method for filling a multi-chamber profile with foam, body and motor vehicle

A method for filling a multi-chamber profile with foam, comprising the steps of:

• providing the multi-chamber profile which is a completely closed hollow chamber profile with at least two chambers, wherein an inner wall is disposed between two chambers of the at least two chambers which are arranged directly on each other and wherein the inner wall separates the two chambers from each other;
• drilling or milling a bore in an outer wall of a first one of the two chambers of the completely closed hollow chamber profile to form a foam inlet and, at a same time as the drilling or milling of the bore in the outer wall, drilling or milling through the bore in the outer wall a through bore in the inner wall, wherein the through bore connects the two chambers;
• introducing a flowable foam material via the foam inlet into the first one of the two chambers such that the foam material is distributed within the first one of the two chambers and is introduced via the through bore into a second one of the two chambers;
• and
• after the introducing, closing the bore in the outer wall of the completely closed hollow chamber profile.
