Tool kit F-119940-TL73 is no longer in production but may be available from distributor inventory.
In VW/Audi 096, 097 and 098 units, wear at the inboard end of the boost regulator bore can reduce the ability of EPC/TV pressure to stroke this valve open. Full boost exiting this valve combines forces with the main regulator spring, increasing line pressure. Sonnax oversized boost regulator valve kit 119940-07K allows the bore to be refurbished and restore proper pressure control.
Sonnax valve body layouts provide a detailed overview of individual units making it quick and easy to determine what’s available for the specific valve body you’re working on. See all Sonnax valve body layouts.
