5) Check the electropneumatic pressure converters (=EPDW)

The electropneumatic pressure converters are activated individually so that -450hPa is routed to the wastegate. The adjustment of the wastegate can be partially observed from above. During the activation, the vacuum can be checked using a manometer, if necessary. If the vacuum line is disconnected, a delay of the pressure build up is to be observed!
