Warnings
WARNING: the compressor does not break down by itself.
It is therefore essential to understand the causes of its malfunction before replacing it with a new or reconditioned unit in order to avoid a repeat failure.
The general causes are:
The relay is not replaced and the compressor keeps running until it seizes; always replace the relay.
Even a very small hole in the air spring, in the height adjustment valves or in the system will cause the system to leak and the compressor to activate more than necessary to restore pressure; the larger the hole, the faster the system will discharge. Therefore carefully check that there are no leaks of any kind.
The compressor draws ambient air through an intake hose which in most cases is fitted with a filter. If this hose or the filter are damaged the compressor may inhale debris, dust and water, resulting in internal breakage and corrosion of the piston and cylinder. Therefore check that the hose and filter are intact and dry internally.
