Doesn't seem to be speed related, the noise frequency doesn't increase with engine speed.
Pull into the work parking lot, pop the hood, give it a little gas... noise seems to come from the front of the engine by the vanos unit. 'Course the water pump is right there too, but it's only 2 years old. And it doesn't sound like the classic water pump squeal.
Haven't got my Bentley's at work, any way to t-shoot the Vanos? Or should I be looking elsewhere?
