Low level buzz/ringing from around battery area when hood open

Post by Tamtoot » Thu Oct 11, 2018 12:14 pm

Good day,

I was having a check on fluid levels today and heard a buzzing/low level ringing tone from around the battery location area. I closed the hood then listened through the wheel gaps and could still hear this low level noise. I cannot determine the source.

Could it be anything to do with the NATS system, as the security warning light symbol blinks every few seconds when the ignition is off and doors+hood are closed?

Can anyone please advise if this is considered normal?

Thanks in advance.

I can confirm that both my Qashqai have the 'low level buzz' under the bonnet. Ford C-Max also had it. Nothing to worry about.

Could be the air intake join near the battery vibrating. just grab it hard and see if it stops. If it does get a big tie wrap around the join, that's what I did for the vibration I was getting.

It actually happens when the engine is off, just the ignition on, so is something electric like a transformer whine rather than anything vibrating.

My Mini Coupe used to make a buzzing noise when I popped open the bonnet. Was reasonably loud and I always thought it was something to do with the alarm system. Everything was working perfect with the car apart from the battery that was on its way out and caused the Start stop system not work.

The only think I could suggest from this, its that its a possibility the battery may need replacing?

It's happened on all 3 of my Qashqais and I've had the battery replaced on 2 of those and it still happened. Perfectly normal.

Above the battery there is a pressure converter that buzzes on mine.
