Help. Noise and steering vibration at low revs + idle!!!
Can anybody advise.
My Brera makes a brrrrrrrring noise at idle and low revs and is slowly getting worse. It use to come and go but is there most of the time now. It is really bad when the revs drop such as when you bring the clutch up. At higher revs it is less noticeable. The first thing I thought of was that it could be an exhaust issue such as a leaking manifold as it appears to be coming from the engine bay. However why would it come and go!! It's also worse when at low speeds and I can feel vibrations through the steering. I am now wondering if this could be a steering issue. I wouldn't have guessed that the steering could make that kind of noise but could it be the power steering pump? Having read threads debating the ins and outs of the steering fluids (red and green) and the updated reservoir I'm really wondering if this could be the problem (I have red fluid and I'm not sure if I have the old reservoir (57 plate but 210 Version). It isn't really a whining noise, like I said more of vibrating brrrrrrrr......and it often makes the noise from start up and is related to the revs as it appears to disappear from 1500rpm upwards. When the noise is present the steering is noticeably more notchy and steering at very low speeds (mini roundabouts/car parks etc) make the vibrations and noise worse. However could this still be the case if it was an exhaust issue, or something simple like a loose heatshield?
Any help would be great.
