Volkswagen have brought out a new diverter valve to replace the standard diaphram type with a piston type. The diaphram type has had many revisions since it was released but still suffers from failure, the new piston type should stop all these failures and is being fitted standard to all the VAG 2.0 TFSI/TSI engines from January 2009.
The unit can be retrofitted to any of the 2.0 TFSI and TSI engines from VAG, this includes all Audi 2.0T and all Volkswagen EOS, Golf V, Jetta V and Passat B6 2.0T engines.
