Please note
The exhaust is passed through channels 3/5 and 82/84.
These connections must not be sealed with blanking plugs.
Exhaust channels 3 and 5 are grouped together in the CPV
valve terminal. Separate exhaust restriction of channels
3 or 5 is not therefore possible.
Restriction of exhaust 3/5 on the vacuum generator
plates
(Ident. codes A and E) is not permitted.
