Serpentine Belt for Audi A4: PVC Coated Fabric
This serpentine belt for the Audi A4 is specified around pvc coated fabric, which decides how it behaves in service far more than the part name does. We build to a written specification — base material, dimensions, finish and packing — and hold that specification on file so every reorder reproduces the approved piece.
The usual reason a programme changes supplier is not unit price. It is premature wear on the first batch, or inconsistent hardness between lots. Both are specification problems, and both are preventable.
