– Function: vacuum switching/regulation for VGT/wastegate control of the turbocharger and intake flaps according to the instructions of the control unit
– Location: engine compartment (near the turbo/intake tract; specific position according to the model)
Condition and packaging
– Used part, tested, functionality guaranteed

Symptoms of a faulty valve
– Loss of power, erratic acceleration, emergency mode
– Turbo pressure control/intake flap control error codes
– Audible “click” with no actuator response or vacuum leak
Installation recommendations
– Replace cracked vacuum hoses and check check valves
– Connect the tubes according to the port markings (VAC/OUT/VENT) – the confusion will cause incorrect regulation
– After assembly, delete the errors in ŘJ and perform a test drive; in some cars, a reset will help by adapting the turbo regulation
