Squeal when idle, not when accelerating
I've been searching for an answer here but can only find the opposite situation. Especially in damp autumn weather (!) there is a squeal/whine when idling or when I take my foot off the accelerator, but when I press the accelerator, the whine/squeal stops.
There is also what sounds like rustling leaves coming from under my feet, audible from outside too. It's not rustling leaves but this seems to be connected.
I am not mechanically minded, so please don't suggest I try something myself. Could this be connected to the alternator belt, or cambelt, or something else. Is it something I need to get checked out sooner rather than later (Allan service will be due in March). Year 2000 diesel.
Look forward to receiving your knowledgeable response!

Re: Squeal when idle, not when accelerating
Squeeling when the weather is damp is almost always due to a slipping belt (that drives the alternator for example). It won't be the cam belt and can be fixed by any mechanic. However, if it's been going on for a while you may need a new belt ( not expensive) as the noise is the belt slipping which tends to damage it.
Not sure about the rustling leaf sound.

Re: Squeal when idle, not when accelerating
Mine is doing this when cold and has been for some time. Adrian my mechanic changed (i think) thr aircon tensioner and that seemed to cure it for a while. But now its back. Its in for annual welding(!) and MOT next week plus to have a look at this problem. Will try and update you (I'm wondering if its early signs of crankshaft pulley starting to go - the two halves are bonded with rubber i think, which can let go?)
Re: Squeal when idle, not when accelerating
Lift up the passenger seat and look at the alternator belts (2 belts). A customer had a rustling noise and squeal; one of the belts had frayed.
And check the bottom pulley as suggested.

Re: Squeal when idle, not when accelerating
Thanks both. I've just started a new job and don't have the time or energy at the moment to look at this. I've dug out the alternator belt set I bought ages ago from Ian and booked Tonto in with James (Premier) to check and sort on Monday while I'm at work.
Now that it's gone warmer, it's stopped squealing!

Guess Tonto doesn't like the cold.

Re: Squeal when idle, not when accelerating
Exactly the same with mine. Adrian the mechanic tweaked them and no more squeal. Tis strange though as i never had that problem with my last set of belts, which is why i didnt think it was that simple. It'll be interesting to see how long they go before they start at it againJillygumbo wrote: ↑Wed Nov 21, 2018 6:09 pm All sorted now. Twas the alternator and aircon belts! No more squealing!

We love a simple fix.
