I went to Germany this week and left the car at High, and disconnected the battery. I came back, reconnected, as I've done many times. Started her up no problem, and went to run an errand...but...no response when i went to lower the ride height. Being stuck at high is not the worst thing in the world, but i need to use it on the road tomorrow, so looking for a fix. The system has been fine for 5 years, but recently in the last few months it wd sometimes sag at the Rear RH corner when i left her parked. I'm convinced it was the system doing the deflating and not a leak... i could be shopping for 5 mins and would come back and it had gone down... other times it would just sit at standard, and it would sit at high all day long. But now as i say it wont adjust from High.... Well, I say wont, but i can plug nano in and make the car go up and down, all the sensor bit counts adjust dynamically. Fuses are ok, and switches test ok on the nano - except the raise/ lower one - which would be a red flag, but i took the switch of my other P38 and nano reads the same - no response to the ride height switch.... I'm suspecting the EAS ECU, which I suppose is easy enough for me to try... but, does anyone have any alternative theories?
