Re: high pitched noise on the motorway?...
I posted a similar thread about a noise coming from my 156. Although mine makes noise at around 30. but its the same sort of situation, if a accelerate the noise goes away, if i slow down the noise goes away, but its just when maintaining speed, as you have mentioned. Im getting mine checked out by my dealer, i suggest you do the same. If i was to say, im an trainee engineer, i would say it sounds like a noise coming from the drive shaft?. Is that what yours sounds like?, Hope this helps
