  1. Can anyone identity this noise? High pitched noise

    Alfa Giulietta
    Hi, I've recently noticed a slightly high pitched flutter type noise on my 2011 1.4 multiair. It's at a certain rev, maybe about 2500 ish I've attached a link to a video as it's easier to hear than try and describe it. Seems to be more noticeable when cold but always there even when warmed...
  2. Deep burble vs high pitched rasp? (Exhaust question)

    Alfa GTA
    Hi all I have a 147 GTA which I bought with a ragazzon back box already fitted. It has this really nice (IMO) deep burbly sound at idle which shakes the house when it's in the garage I've been looking to upgrade the exhaust system but to be honest with YouTube videos I can't tell much of a...
  3. GT Rear Parking Sensors - New Higher Pitched Beep

    Alfa 147, 156 & GT
    Hi all, Today I heard a higher pitched beep higher than the normal parking sensor beep when I was reversing. Has anyone else experienced this and does anyone know what it is? I have had my GT for about 9 months, and should mention that only the two outer sensors seem to work. Today I engaged...
  4. persistent high pitched squeak from dash

    Alfa 147, 156 & GT
    not all of the time, but certainly a persistent companion on every journey at the moment. I'm finding it very off-putting. Is it the dashboard itself? Dunno - but that seems solid, and no 'damping' by placing my hand on the dash relieves it. I tried holding the steering wheel firmly because...
  5. high pitched whistle after fitting new flexible front pipe

    Alfa 147, 156 & GT
    Professionally fitted front pipe apparently has no leaks but I now have a high pitched whistle on hard acceleration in lower gears. i see it may be a a leak in lower turbo pipe but why did it not make the whistling prior to fitting the new exhaust? could it be that there is now more pressure...
  6. high pitched squeal when I turn left slightly

    Alfa 147, 156 & GT
    Guys, When I turn left slightly I get a high pitched squeal, which vanishes when I turn left even more. When I press the brakes it gets slightly louder and then vanishes too, its all coming from my passenger side wheel area. I am assuming its the brakes, because it gets louder and then...

  8. Help pls. High pitched noise from 147

    Alfa 147, 156 & GT
    Can someone shed some light. I have been getting high pitched squealing/whizzing noise from my 147. It doesn't kick in until I usually drive over 40mph. Seems to stop when I put foot on brake. Thought it was brakes but mechanic advised brakes seem fine. Could the timing belt be causing this...
  9. High pitched sound in the cold

    Alfa 159, Brera & 946 Spider
    Hello everyone. I need some suggestions as to what this could be. I have moved to a small town 4 hours from Sydney and the mechanics here don't seem to know much at all about Alfas, let alone diesels. I have noticed over the past few weeks that on cold mornings I can hear a high pitched whirring...
  10. High pitched squeeking

    Alfa 159, Brera & 946 Spider
    My 159 has developed a squeak that only seems to emanate once the car has warmed up. It's very loud and can be heard from the car externally and it’s also only noticeable when the car is moving very slowly or when setting off from being stationary. Has anybody got any ideas as to what it could...
  11. Bose high pitched noise

    Alfa MiTo
    My 12 year old son loves our Mito but complains when he travels in the back of a high pitched noise from the tweeters, my 14 year old (and my wife and I) can't hear it. Anyone else had a similar issue? I should add this is with the Bose and RadioNav fit.
  12. High pitched noise from under car!?

    Alfa 147, 156 & GT
    I'm trying to track down the source of a high pitched whining noise from under the car, which is audible while sitting in the car at idle, and quite noticable from outside the car, the engine noise at anything over about 1500rpm drowns it out. It's one of those noises that seems to be coming...

    Alfa GTA
    Driving home last night in my GTA selespeed SW, I noticed a high pitched whine while turning in a right direction. It stopped when the wheel straightened. Didn't make the noise turning left. At first I thought it was the radio, such was the pitch of the whine (almost sounded like audio...
