Spotted this button today on the driver seat. It's next to the height adjusters but when pressed does nothing.

Anybody know what it's for? I've had a search on google but not getting much luck...

Thanks guys.

Hi, i am new here, so forgive if this has been covered, i can not see very much on it.

I have GTC SRi 2.0 cdti 2012 and i am going to replace springs with 30 mm lowered all around.

I read that the ride height for an Astra J is 112 mm.

Where exactly is this measurement taken from?

I measured 160 mm from the bottom of the rubber under the front bumper to the ground.

A typical kerb is about 125 mm, so it doesn't give much space.

Any input appreciated

Pat.
