re: frequency valve
Phil: I checked in the bentley manual for the 4000/coupe 84-87 including
quattro turbo, and in the bentley for the 100/200 89-91. The index for each
did not list a frequency valve under the various fuel injection sections.
The only frequency valve mentioned was the wastegate frequency valve for the
200 (which included the diagnostics). Is there another name for the thing,
or is it the wastegate frequency valve you are interested in?

Subject: Frequency valve life
a) Does anyone have a view on the normal service life of the frequency valve
used in some fuel injection systems - Audi 034 906 267B, Bosch 0 280 150
b) The ur-quattro documentation is silent on testing the thing. Do any
vehicles document any useful tests of its function?
