The CTS Turbo recirculating diverter valve (DV – diverter valve) kit is intended for Audi B9 vehicles with a 2.0T engine manufactured between 2017 and 2020.
The valve is made from machined T6061 aluminium and features a fully serviceable piston design. It is compatible with all original electronics, does not trigger the engine warning light and allows direct installation without extending the wiring.
The kit replaces the original plastic valve, which can suffer from diaphragm damage, cracked plastic or electrical faults. The piston design ensures a long service life, easy installation, serviceability and a more pronounced sound. The compact dimensions, which are slightly shorter than those of the original valve, also allow installation in the tightly packed engine bays of modern VAG vehicles.
Important limitation: the kit is suitable only for engines with the CYMC code and an IHI turbocharger.
Not compatible with engines with the DMSA and DPAA codes, manufactured from 2020 onwards, which use the Borg Warner 06N145702D turbocharger.
