Not mine, a mates. Paid him an unannounced visit yesterday and he has an eas issue I didn't know about so didn't have my nanocom.
It was raining hard so couldn't fiddle much on his drive. His car is dropping to at least access height within a minute of parking up.
The car, yesterday, had been parked up for around 8 hrs, we started it up, I checked compressor suction which was good and removed the exhaust silencer. Didn't time it but seemed like 3 minutes and car went to normal height, no loss of air from the silencer port,switched off the engine and lots of ticking from the valve block along with frequent air dumping from the exhaust and the car dropped in quickish stages to access, maybe to the bump stops, puddles and rain prevented any further investigation.
My first 'wet behind the ears' thought is an, airspring side of the eas, leak rather than a valve block, level sensor, ecu issue. Once up he can drive it no issues and he can't hear the compressor running whilst driving but I can't hear mine either which is performing as it should.
I've suggested the soapy water leak test for now but any other pointers he can try before I can get round to his again with the nano?

Most likely a leaking airspring. Pull the EAS relay located under the passenger seat before it drops and see if just one corner drops. If there is no fault yet, Nanocom would not have helped.
 
+1 on leaky airspring. Otherwise the ECU can get it's knicker in a twist if someone has done diagnostic, but not disconnected properly.

It's important to always keep the ignition on & do the software disconnect & unplug either Nanocom or EASunlock before switching ignition off. That way the ECU does it's natural shutdown when the timer relay disengages. Remember the BECM keeps the EAS awake until you have exited the car & closed all doors !!
 
Another update. He says it's still performing as it should. He's had the passenger side kick panel off and there is quite a bit of green on the white block terminals. He's cleaned them up for now and says everything is still good.

Mine would sometimes 'dance' down to access height as soon as you turn the ignition off. Never found out why and didn't always do it.
Really helpful aren't i

Mine also did it occasionally but, I found a way of stopping it, I would let it settle for a few seconds before switching off and it didn't do it, I just forgot about it then, realised it wasn't doing it anymore, I would return to the airport car park after 2 weeks away and find it hadn't dropped, I have no idea what it was and didn't mess with it, Nanocom showed no faults so I thought, if it aint broke, don't fix it.
