S85 VANOS Aftermarket Solenoids
The S85 VANOS was the latest for a reason: it was the arguably the most complex.
The high pressure pump, the internal & external line supporting 1,000 PSI + and its solenoids are all components known to fail.
As a part of my Build Journal entries in the Mechanical Program, I document the failure symptoms, these aftermarket solenoids and their performance.

These require a bit of diassembly, and the access to one particular bolt is a PITA. A few VANOS bleeds are recommended.
