My 2014 E class estate (with 30k on the clock) has started sagging at the back overnight, with the message on the dash "Wait - Car rising" or something similar.
It pumps itself up and off we go.
The first time I noticed this was a couple of days ago when I came back off holiday so the car had been standing for 2 weeks. I thought this might be normal and once it had pumped itself up that would be fine.
But no. It sags overnight now (on both sides - don't know if one side goes down first - I'm assuming both sides are linked and not independent)
I've looked at past posts and understand that somewhere there is a leak, but was wondering if it might have something to do with the hot weather and pressure increase in the system venting during the day, and it all cooling down overnight.
I suspect not though and the coming cooler weather will show me if this is true or not!
So does anyone have any insight into how I can identify the source of the leak (is it worth paying for a Star diagnostic) or is it most likely to be one of the airbags and I should replace them both as if ones gone, the other isn't going to be far behind.
Does anyone have any direct experience of the relatively low cost items available on Ebay sourced from China, or is there a better source that people have used.
The suspension is the standard estate suspension ie its self leveling, not full airmatic
