Land Rover Repair: Air Suspension on P38 range Rover, p38 range rover, piston seal


Question
My Range Rover sinks in a lower position and won't rise up, and i've tried everything possible , sometimes it raises up and now lately it does'nt get up again and it was a bumpy ride home last time it messed up. The air suspension compressor comes on once in a while and i've just changed the rear rubber balloon 6 months ago and i've owened the Range from Brand New with only 45000 miles on the clock as i drive it occassionly, pls advice on what to do.

Answer
There are several orings in the system that need to be replaced as well as the springs, if you've only changed one the other 3 probably need to be replaced soon as well.  

Running with leaks for a while will put extra wear on the compressor and wear it out faster, you probably need a new piston seal in it.  

I have full overhaul kits here:

These include everything you need to restore your air suspension to original condition.  

There is a free program that allows you to reset the lockout in the computer to bring it back to life, for download here:
