| Suspension Problem (nothing on the front) |
|
In a nutshell yellow suspension light and
C1131-92 (AF) Air supply - Component failure - performance or incorrect operation
Compressor 18 months old. Found leak in reservoir tank, replaced that. Replaced valve block in front of compressor.
Found leak in rear pipework behind rear wheel, fixed that.
Took to garage where ex Landrover mechanic works.
Told me compressor not happy having worked hard with leaking tank - replaced with new Bearmach kit from AF. He was worried about front valve block so that was replaced.
No better. Told me the ECU had failed so got a 2nd hand one. He couldn't programme to car.
Went to garage with rear working but front low and yellow light, came back on bump stops with red light.
Flashed module with IID tool. Can clear faults and adjust rear height using test valves. Nothing on the front. Red suspension light back to a yellow one.
Still same code:
C1131-92 (AF) Air supply - Component failure - performance or incorrect operation
Still on bumpstops at front. Mechanic claims he can't find a leak. Went down sloly but evenly on the front over a couple of weeks so not an airbag.
Height sensors reading and change when jacking the car up. Have tried adjusting the values with IID tool.
Any help appreciated!

sounds like front valve block ???
or maybe the computer raises the rear first and the compressor is overtemperature before it raises the front, so you need to rule this out. By starting the car when the rear is already raised.

Long shot. Check that the plastic pipe that runs adjacent to the heater exhaust pipe -front near side -hasent got a leak due to excessive heat from the pipe. Once you have defeated the idiots any job is half done. Pity there are so many idiots to defeat.
