Whine and thump when idle
Hello AR friends,
I bought a 2011 159 2.0JTDm in Dec 2013 (~60,000 miles on the clock).
This morning, after I'd already driven it for around 15 min, when I stopped at a roundabout I heard a whine and then a thump/ knocking (the thump repeated every 3-4 seconds). When I revved up and drove away, the noise disappeared. At the next braking point, a traffic signal, the whine and knock repeated. Home was round the corner, and when I pulled into the driveway the same noises occurred at parking.
Later in the afternoon dropped it at my local Alfa specialist - but driving there the sounds didn't repeat themselves.
So - symptoms: whining and knocking when idling (but only after being warmed up). Noise disappears when on the move.
Nervously waiting for the mechanics to come back to me. Any thoughts on what the cause might be meanwhile appreciated.
