My VVT on my S4 Spider is sick, with a malfunctioning solenoid and a broken control valve pin.... Anyone have one or know a source for these? I found a couple of ebay listings for solenoids, but nothing for the pin.
In the process of replacing my head gasket and, by the way, thanks to jcslocum and all contributors for the fantastic guide on the Spider Technical FAQ Digest!!
I am at the step of removing the VVT and noticed the amount of oil gunk on...
I've read all I can find on the BB regarding the VVT (which won't come up in a search using only "VVT"). I get how it works, but am still stumped.
Impedance checked the throttle position switch - 18-2 closed at idle and 18-3 closed at full throttle.
