Recommend new battery (and weird noise)

Bizarre though don’t you think? Two different words for what amounts to a near identical process and just adds confusion to most people

Thanks for all replies. Going to get one with the same specs then register it in the car.

Yes, it’s a 2011 20i so falls into that category.

You can code start/stop to always be off and not default to on with Carly right? Think I’m going to get Carly...been thinking about it for a while but never did so and these two procedures might pay for itself and then I can play with other settings.

Is there a sign these are failing? I ask because I saw a YouTube video once showing a car that had the beginnings of problems and under the bonnet was a whine when revving.

My car makes a whine type noise in 1st and 2nd when accelerating but after that it’s not present (or noticeable). But I’m not sure if it’s the turbo?

Does this sound related?

I’m not sure what the whine is but it’s probably NOT cam chain related...IMHO..

Thanks.

It starts at about 1750rpm going towards and past 2000rpm and only really seems noticeable in 1st and 2nd when accelerating, there is plenty of pull etc.

I think I'm losing it, as this could just be the normal sound in the lower gears, perhaps due to gearing? Almost like an electric motor sound, but not like an electric motor sound. My description makes no sense, I am aware of that

People on this Forum often lose it so I wouldn't worry on that score..

Sounds like transmission related noise..is it manual?

'pull' wise is not relevant..the N20 engines 'pull' till the cam chain jumps the camshaft sprockets, then there is 'no pull'

Doing an oil change and cutting open the filter is a good diagnostic..if you have plastic swarf in there then its on its way to 'good night vienna'

Yes, its a manual. I'll try and check if it happens when in neutral or only when actually in gear.

Often you get a minor bit of whine from manual box and/or rear diff ..

Camchain wise if you remove oil filler cap and peer with torch if you see ANY swarf espcially a brown plastic then you are in deep doo-doo

Thanks.

I’ll look in the oil cap and see if I can see anything.

Did have an oil service a month or two ago but will let you know what I find.

Looks clean inside. Outside is minging though!

So here's some videos:

This is the one I referred to earlier, that has the whining noise (only need to listen to first 25 secs)

Here's mine. Deb was in the car revving to 2k rpm and kind of holding it at that level. Don't know why I kept moving the camera.

...and heres an unrelated video of a monsoon earlier in the year! (sh1t my pants!)

Changed mine to 80ah to give a bit more...

I was very lucky not to crash - luckily the bit where I was heading for the curb was just level grass, not a curb stone etc. I bet the mini bus driver chuckled at my misfortune.

Never seen it flood there before so wasn’t expecting it, should’ve probably been a bit slower as it was raining but hey ho, was fortunate that day. I was on the Goodyear non run flats, wonder what the outcome would’ve been on runflats?
