2 squeals when turning ignition?

[BiggerWhiskey]

Just noticed I’m hearing 2 squeals from the engine bay whenever I turn the key to on - happens every time, the video sounds a little louder than it really is since I was in my garage…doesn’t sound normal, any advice would be appreciated. Thanks!

Does not sound right. If you mean when you first turn the key to the accessory position prior to turning it to start I get a click then the background electrical whine but no mechanical sound like that.

Yep, whenever I turn it to the on / accessory position - I get 2 squeals, followed by 1 shorter squeal (and not as loud) when I turn the key to off. Happens every time, so it’s easy to recreate.

Any idea what “pumps” might be turning on when you turn the key to the on / accessory position, or if this is a known issue. It sounds like a pump or something - but I’m not exactly sure. Vehicle seems to run fine, it’s just when I’m turning key on prior to starting - and then when I turn off.

Mine does the same. A high pitch squeal. I talked to the dealership and they said it was the power steering unit. Could have a future recall. Not now.

Fuel pump?? Power steering pump??

Just sent you a direct message - but Im also going to post a link to a longer video if anyone wants to take a look / listen....the forum wont let me attach anything larger than a few MB it seems...

It definitely seems to be coming from the left side of the engine bay...possibly even under the actual engine...

Your dealer said they may recall the psu ? Why? Due to the whine?

BTW I have a diesel so may be different sequence on startup. But the power steering pump should be the same, I don’t understand why it would prime on startup so am calling BS on that. On the petrol you probably would have a fuel pump prime prior to start.
