Hi Gang,
I have just finished on my brakes, when the D3 now has a suspension fault. Hitachi compressor.
It has has slow EAS since we purchased it a few years ago and has been drooping overnight, but it progressed to ''Normal Mode only" messages.
I worked through the dessicant kit from 4X4 air seals and have also replaced the seals in the reservoir valve block, but the fault remained, specifically C1A20 - Pressure increases too slowly when filling reservoir.
Due to this I also ordered and worked through the piston seal kit, finished that today and now have C1131 - Air Supply
There is air coming out of the compressor, I do not know if it is suitable amount though.
The rear doesn't even try to move, even when using the GAP tool to "test the valves".
Two questions I have are
- Is there anyway too "charge" the reservoir? It seems to have at least been drivable before I disconnected and released the pressure to do the seals in the valve block.
- Not wanting to purchase things unnecessarily, I am resigning myself to the fact that the compressor may have finally died, had a pretty good run, but 15 years and 400000kms old might be time. Is there an expected pressure that the compressor can put out if it is working correctly? I don't want to replace the compressor to find it was the valve block and vice versa.
Thanks in advance.
Michael
