F29 is the EAS fuse in the Bosch box. Now to find a sub for F35...RAVE says F5 and F16 arent used, but I don't know if they switch on with the ignition. I'll check tonight.
Neither...After researching my EAS "soft failure" twice in 90 degree heat over the last 2 days, I am wondering which is the better place to start,
replaced my airsprings with Arnott gen III's, rebuilt compressor. My system has no leaks, and has never had any EAS problems,
recurring fault code = "Pressure switch not changing state" as reported ny my eas kicker. It fails to the high position, with the associated flashing lights on the height selector and a brief EAS fault msg.
After much searching and reading, where should I begin? Replace the pressure switch or do the "Brush box" mod. (I'm sure your familiar but here is the link to the brush box repair http://www.falconworks.net/eas/Brushbox.htm) or what do you reccomend?
mine is a MY99 with VIN XA 415??? I check the values from the height sensor and they look ok!!Sensor Out of Range
Some owners have reported the fault condition appearing after replacing the shocks or even jacking the vehicle up on a lift -- presumably the problem here is the axles moving outside the normal range causing a "sensor out of range" signal. If you are replacing the shocks, it might be advisable to disable the EAS and be careful not to move the axles to extreme positions. Another possible cause of this signal is a bad EAS ECU -- in 1998 thre was a Technical Service Bulletin, number 0007, "INCONSISTENT RIDE HEIGHT - ELECTRONIC AIR SUSPENSION (EAS)", admitting that bad ECUs were interpreting valid height sensor signals as outside range. The affected vehicles were in the VIN number range from VA 346794 to WA 409701. The remedy was to replace the ECU (part number RQT100040).

Some strange problem exists with my EAS at the moment.
During the time the car is parked it will gradually lower the car to the bump stops. At first I tought a leaking spring, air line or valve block but could not find any leak. Reservoir pressure remains at 10 bar.
Then I took out the eas timer 15 minutes after the car was parked and cooled down. The next morning the car was at the same height as when I left it with the timer unplugged. Plugged the relay back in and read and cleared the fault codes and all was well for the day but the next day again lowered car overnight.
Checked the ECU memory: No faults.
Because of this behavior every morning we have to give time to the EAS system to pump back the pressure into the tank. The moment you start it will self level and the car comes up but there is not enough air pressure to lift it up completly (The tank pressure drops from 10 to 5 bar) and the light keeps blinking. If you open a door and wait for the compressor to refill the tank to 10 bar the car self levels and all problems are gone for that day. It looks like the springs are completly deflating overnight without any pressure left in them.
Anybody came across this behavior? What did you do to solve this problem?
