The squeal fades when revved but is constant at idle revs, goes completely when the electric motor is moving the car. I put it down to a wet belt, changed back to hybrid mode and carried on driving as I was only about a mile from home.
I made it home parked up and had a search of the forum and a quick google and read a few horror stories, mainly a post from Phillip fisher that made me feel a bit sick.
Would somebody mind watching the below video I took of the car at idle and let me know if you have had this before and what the problem was? I’ll have to get it looked at on Monday morning now but would love it if somebody put my mind at ease in the mean time.

Any help would be appreciated, Andy.

Mine was slightly higher pitched than that and not as loud. But I caught it very early. There is a chance it is the same issue as me.

It could be belts and it could be an ancillary of course. Indeed it does sound quite "belty" to me.

So I am afraid I can't put your mind at rest. The only way of diagnosing is to remove the aux drive belt and see if the noise goes away.

Or if you want to play this afternoon, get a cup of water and pour it on the aux drive belt with the engine running. If the noise changes at all then it is the belt. If it doesn't change then, well, it is not the belt so it starts to look less promising.

Good luck.
