Hi

We live in France and had a diagnostic done on our disco 2 , our online translator tool tells us that the problem is "defect D solenoid suspension compressor "
Can anybody narrow this down to the actual piece that I need to replace please ? or / and advice on replacing or repairing , thanks guys

 

In general terms, your pump assembly, located under the drivers seat and bolted to the frame is failing.
It would probably be cheapest to buy a good guaranteed used pump assembly and replace the whole thing.
If you were here in the States, I could tell you where to buy one but I have no connections over your way.

 

The other option is to replace the SLS with coil springs.
