Land Rover Repair: Range Rover, range rover v8, air suspension

Question
I have a 2004 Range Rover V8 (M62)
my dad was rotating my tires  and the jack slipped accidentally on the front right wheel and the car landed. One day later the airbag went down and the entire system shut off with the message saying Air suspension Inactive. Before all this happened the air suspension was working perfectly. my dad checked all the fuses and relays and they seems to be good. he then took it to a shop to read the ecu but there wasn't any codes. the guy did at the shop did something else on the computer and made the left front air bag went out but in the end he didn't know what happened or how to fix the situation. Could you please give me some help and pointers on how to approach this problem and what could possibly be the cause?

Answer
You need to find a properly equipped shop, and see what codes are stored.  You may have damaged the air bag/strut.  You may just need a reset.  Either way, the only way to progress is by finding a shop with the T4, Autologic or IDS test systems.  Generic scan tools won't fully engage the air suspension computer.  That's where you have to start.

Most people would fix the air suspension but if repairs get costly you may want to look at the new coil spring conversions.  I think Atlantic British is selling them
