Dreaded air suspension fault

[Derek29]

I have a problem with the front end being far too low.

Started the other weekend, driving about fine for a while, then it scraped abit on a speed bump that it never usually does. Driving home it felt funny, I park up and the front is very low.

In the morning I scan it and it throws 3 faults, leak detected and then switched compressor off due to over temp etc. Then the dash warning lights come on.

Jacked it up and remove left side arch liners, compressor comes on and off, I spray soapy water over shock and visible lines and the valve block, no bubbles.

Dash lights don't come and go after doing this, depends what you ask it to do, but front is still low.

The rear is fine. When in lift mode the rear goes up.

Front is evenly low, not just one corner.

I lowered the car about 3 years ago, about 15-20mm, wasn't much and had no problems since.

Anyone had similar problems? Read up there's a relay to change but would rather some input before I just throw parts at it.

Cheers
