2009 S80 Vibration
 

Noticed a vibration coming from the right front area of the car. It is notthe engine however is apparent around 1800rpm. With Car in neutral or parkthere is not vibration noted, above 1800 rpm vibration noise seems to dissipate.Recently drove the car on a 250 mile trip the day before.

Wife noticed an intermittent illumination of the Parking Brake Warninglight, not sure if this is a coincidence.

Car handles well, no apparent controllability issues.

Ideas?

I understand you are saying in neutral at 1800 rpm, no vibration, but in gear and moving at 1800 rpm there is vibration?

If that is the case, first thing I would check is the balance on the front right tire.

I have also had a bad CV axle cause vibration at specific rpms and not at others. If the balance is okay, might want to check the front right axle.
