Had an EAS FAILURE on the way home.

Turned out to be COMPRESSOR FAILURE.

On reaching home I turned off the ignition and heard a hissing as the car visibly sagged.

The compressor dues actually run, but the system won't repressurise with a short open.

I'll leak check with washing up liquid in daylight but that hiss and sag has me thinking a valve is stuck open...

Need the car tomorrow night (Monday).

Accelerated diagnostic steps would be much appreciated.

Okay. All sorted.

Passenger side carpet slightly damp.
WD40ed the EAS ECU connector.

Found a tiny seeping leak in the pipe with the lilac coloured label. Missed it the first time because my dilute washing up liquid needed pepping up with a fresh dose.

Saw back two spring valves were OPEN.
Watched live values creeping up.
15 minutes door ajar.
Pressure valve CLOSE
Job done.

Good work! Thanks for letting us all know the solution.

Lilac hose is the one to the reservoir, so the compressor will have been running permanently trying to fill it before it will rise.
