I have this issue with EAS bumping up and down all the time not findings it's position while driving. It is doing this every 10 seconds when it first start to oscilliate. Even at idle (look in the log from 10min out) it constantly adjust a little but but then it's 4-5mm change. Still enough to keep the compressor going almost constantly. I've tried everything I can think of and read through all the guides and forums I could find without finding a solution so I'm trying here. Every suggestion will be appreciated
Front is going up/down between 124 and 105 in standard height and 104 to 88 in highway - 19bit and 16 bit / 29mm and 24mm
Rear is going up/down between 123 and 109 in standard height and 104 to 88 in highway - 14 bit and 16 / 21mm and 24mm
I have tried following:
-4x Brand new sensors from island 4x4 (2 x Rear Height Sensor 97-02 (OEM) ANR4687G £119.98 2 x Front Height Sensor 97-02 (OEM) ANR4686G £119.98 )
-Measuring constant 5V reference voltage at the sensor. No interference/bad supply showing when using oscilliscope to debug either. Anyways, sensors is just confirming the error so they do work from what I can figure out.
-Brand complete new valve block with solenoids, pressure sensor and so on..
-Overhauled compressor. Fills the tank from dead empty in 7-8 minutes with the door open (so it blocks the constant adjustment)
-Brand new EAS driver pack
-Used EAS ECU from ebay (could ofcourse have the same error as my old unit..)
-Calibrated new sensors with height blocks according to rave
-4x new air springs
-Cannot spot any air leaks with soap water. Also if I read off the sensor heights, open a door then they stay in place without going up/down. Compressor then also fills the tank and it stays full without the compressor starting again.
-If I let it stay on a level concrete floor it's constant adjusting so the compressor runs all the time. Not major adjustments but small and just enough to keep compressor going.
-Soldered the EAS connector down on the left/front, inside of the car in case of bad contact in the connector that is prone to water ingress there. two of the leads was black copper but I cut it untill it was nice and clean copper and solder+shrinkwrapped it.
-Visual inspection of the ECU connector looks good. Voltage supply at the ECU also looks good without disturbance.
