I have taken the cover off the compressor and got my wife to start the engine with the doors closed. Couldn't feel any signs of life from the compressor or vibrations with my hand on it. Therr are a couple of clicking sounds when the engine is turned off which I am guessing might be valve solenoids. I have ordered a used compressor from ebay. Should I order a filter insert for the filter line? I have seen one for £6.99 on ebay whereas the lines are £40 - £50. I have sprayed some penetrating oil on the rusty bolts holding the compressor case on. I checked fuses and fuseable links and found all ok apart from headlight sprinkler. Yay, that is now working. I didn't even realise it wasn't working. I will change the other airbag at the same time as the compressor, as I bought a pair.
If all this fails, I might have to go down the road of sticking coil springs on. Can you tow with coil springs? How much do dealers charge to reprogram the system? Can you do this with Hawkeye or Lynx ( or even Foxwell nt510 )?
Thanks
