Even under stock boost pressure, the rubber diaphragm in the original 2.0T diverter valve can fail. When the seal fails, the boost escapes past the turbo, which significantly reduces performance.
After many revisions the entire unit was redesigned, eventually resulting in the Revision D diverter valve, which utilizes a piston in place of the rubber diaphragm.
This mechanical design that is more durable and is a great upgrade for all stock or modified 2.0T FSI & TSI engines.
