I fitted Avon ZV7s, which are quieter than the Bridgestones but nothing major. Don't expect a big improvement regardless of what tyres you fit.

Sadly it will always be loud, regardless of what tyre you fit.

I changed tyres, sound proofed the boot area and arches which made no disernable difference.

I bought this Yuasa battery for my 1.4t non S/S: https://www.gsfcarparts.com/971na0400?a ... gKrAPD_BwE

075 3000.

Wished they kept it in the 2020 model, then I would simple upgrade next year.

No other hatch is grabbing my attention for the 2nd hand value.

They all have them but some only have one, so make sure its on the side you need.

The pipe on the side is the vent tube that must be attached to avoid explosion. Most batteries have a vent hole on both sides but only one is needed on the Astra so the other side gets plugged.

Batteries in the engine bay don't generally use tge vent tubes as they are in open air.

You can't, it's a single moulded piece.

You can seperate the switch from the chrome piece but you have to remove the whole unit from the boot.

Check the vent ducting as it might be catching.

If the facelift had the 1.6T then I would.

Exactly what I did. Be careful with the blade.
