L322 L322 Suspension dropping overnight with batter connected

TrustyBib · May 17, 2024

Hi all,

I have a 2007 L322 3.8 TDV8 and it’s just developed a fault where if I leave it parked up overnight with the battery connected by the morning the suspension has dropped all round by the same amount.

I’ve had the battery disconnected for a week now and no corner has dropped a single CM.

I’ve scanned the car with my Gap IID tool and there are no errors.

Bit lost as to where to go from here. Any help appreciated.

P.S. I’ve searched the forum but couldn’t find a resolution to this specific issue.

All I can say is.

With battery connected it drops so "it" thinks something is wrong or a leak.

Battery disconnect it doesnt drop = No Leak.

What do the height sensor readings look like on GAP, cos that seems to be the only thing that would make the car think it needs to level itself (down)

Is it parked on a reasonably level area?
