Question: Storey, I bought your product and it reset the eas faults and read them. The range rover’s air pump could not raise the vehicle up. I took the air hoses off and filled them with air, then used the V3and the vehicle stayed up for two to three days. My wife took it to school…

Question: Since I last emailed you I have rebuilt the compressor and the valve block. Jumpered at the ECU cable to raise the vehicle all the way up and lower all the way down. All works great. Plugged the ECU back in and the compressor fails to run longer than a few seconds. I jumpered…

Question: Storey, Can you provide any insight into the error messages that I read in? They were something along the lines of: “pressure switch stuck high” and “vehicle moved”. I would believe that the first one is the pressure switch that signals that the air tank is full and it might be a good idea to…

Question: Hello Thank you for the EAS fault code reader and . It is amaising:) Can you please tell me what this means? FR Valve Stuck Closed Thanks Dag Roald Norway ANSWER: All leaks in the EAS system must be found before any of the EAS Fault codes can be used. I would guess that…

MKIII EAS Fault interpretation

—

by

Fault interpretation: When a fault is detected, the ECU will attempt to maintain a comfortable ride quality with restricted functionality of theair suspension system. The system functionality depends on the severity of the fault. The faults are defined as minor or major faults.Minor faults are: Most sensor faults (hardware faults and plausibility faults) Cross link…

MKIII EAS Fault Detection

—

by

Fault Detection:The air suspension ECU performs fault detection and plausibility checks. Fault detection is limited to faults that the ECU can directly measure, as follows: Sensor hardware faults Valve hardware faults Sensor and actuator supply faults Bus failures ECU hardware errors. Plausibility checks are checks on signal behaviour are as follows: Average height does not change correctly Height changes too slowly Suspension…

MKIII EAS Height Sensors

—

by

EAS Height Sensors:Under normal operating conditions, the air suspension ECU keeps the vehicle level at the ‘current’ ride height. Theincoming height signals from the sensors are passed through filters to remove irregular signals produced by roadnoise or other irregularities. When the vehicle is stationary or a height change is in progress, the signals are passedthrough…

MKIII EAS Geometry

—

by

The independent front suspension offers a reduction of un-sprung mass over the conventional beam axle design. Thesuspension geometry features negative ground level off-set for improved control under braking. The suspension armshave been designed for maximum ground clearance. Suspension geometry can be adjusted via the strut top mountfor camber and on the steering rack track…

MKIII EAS General Operation

—

by

General:The main function of the four corner air suspension system is to maintain the vehicle at the correct ride height,irrespective of load. Additionally, the system allows the driver to request ride height changes to improve off-roadperformance or ease of access or loading. The system automatically adjusts the ride height to improve the vehiclehandling and dynamics…
