It has happened twice but it is definitely not down to road surface. Friday it happened after 25 minutes driving at 70mph but not noticeable at low speeds. Today, in the way to IKEA after a few minutes driving and at 70mph it came back. It disappeared when I got into town. I took the same route in the way back but I could not replicate it.
The noise is similar to running with a tyre very low in pressure. Its like a humming noise and quite loud. Changing lane, speeding up or slowing down does not appear to have an effect on the noise. Tyres appear to be fine and pressure is OK too.
The car is a manual 2011 C class coupe with just 55K miles. Any ideas?
