Vacuum System, Checking: Procedure
WARNING: This page is about a different car, the 2016 Audi A3 and 2015 Audi A3. However, it is still accessible from the selected car via links, so may be relevant.
-- Check all vacuum lines in the vacuum system for:
- Cracks
- Damage caused by animals
- Crimps
- Leaks
-- Check the vacuum line leading to the solenoid valve and from the solenoid valve to the component.
-- If there is a fault, check the vacuum lines for the named component, but also all the vacuum lines to the other components.
-- If using the :VAS6213 does not produce any vacuum or if the vacuum drops again right away, then check the hand vacuum pump and the connection hoses for leaks.
