Do the 2008 models (335i specifically) have the clutch delay valve? If so,
is it same restriction to fluid flow as the one on the previous E90 models,
i.e., 325, 330?
Wondering if they changed/eliminated it due to the increased
horsepower/torque on the 335 engines, given the possible increased clutch
wear on a more slowly engaging clutch from the CDV?
Not sure about 2008 specifically, but 2007 335i still had it. It's the
"lock valve" in the diagram below:
I think the higher horsepower/torque would be a reason to keep the CDV
even more. The purpose of the CDV according to BMW is to reduce
drivetrain "shock" resulting from quick clutch pedal release. The more
powerful the engine, the more shock.
