Several weeks ago whilst driving my 96,000 miles Fiat Croma Eleganza 1.9 JTD MultiJet 16V Turbo Diesel 150bhp manual, gently at about 50mph, I noticed a continuous droning / humming noise.
We can't reliably identify which part of the car this noise comes from – front or rear, off or near.
The noise is not noticeable until about 40mph but the noise is always there.
My trusted mechanic has had the car up on ramps and checked all wheel bearings and found no faults.
We've replaced both rear tyres but the continuous droning / humming noise is still there.
There is no vibration, the car runs smoothly and steers well.
The car is regularly serviced, most recently 2 months ago.
Any ideas?
