Hi all,
still struggling with the air suspension.
It says air suspension not working and ive no ride height led light or fault light in the middle BUT it stays up and looks good ,air compress coromes on occasionally and it sits level .
When i plug the maxi reader it says can fault and articulation fault ,if i clear all is well until 2miles down the road when air suspension fault pops up.
Ive changed all four sensors with new and still no luck . when i try resetting the suspension with the rsw ,lower ,evacuate etc it does it but i still get articulation fault after going down the road .
I have noticed though that the front right reads + 16 mm but the front left reads -12 mm BUT the motor is level .
Ive even swapped sensors frommy other "good" working l 322 motor and the same readings occur . Does this indicate i may have a wiring problem in as much a bad earth ,poor positive or bad signal cable ?
does anyone know what the three wires are in as much which is earth,which is + supply and the correct voltage ?
many thanks to anyone who reads and extra special thanks to any one who might be able to enlighten this ole man
btw when going its awesome !
I know everyone says the 4.4 is better but the td6 pulls my cattle box full 2.5 tonnes (honest officer ) up a really really steep farm lane before i hit tarmac with more than enough umph for me
 
Have you calibrated it with the new sensors?
The sensors have a 5v signal (suspect center pin).

Many thanks to all that replied ,
Taken sometime but got there eventually .
Turns out the front two ride height to harness connectors weren't great . the one no longer clicked in fully ,faulty readings and the other had really bad electrical corrosion on the back of the connector . I bought two new ones off flea bay and soldered them on . quick reset with the rsw software and hey presto a dancing l 322 !!!!! normal to off road to access easy andmotorway mode on bypass motorways
Thanks to all
