Bentley ride height keeps dropping

Bentley ride height keeps dropping, need someone near Al Barsha who knows these cars

My Continental GT has started sitting lower than it should on one corner overnight, and although it levels out once I start it, I know this isn’t normal and it’s getting worse. I’m near Al Barsha so I’ve been looking for Top Bentley ride height repair in Al Barsha, but I’m not sure whether this is a leak, a valve block issue, or something with the compressor. Has anyone had this happen and found someone who actually diagnosed it properly rather than just replacing parts until it stopped? Also, is it safe to keep driving short distances while it’s doing this, or am I risking damage to the compressor by continuing to drive? I’d rather sort it now than let it become a much bigger bill.
