I've noticed a fairly loud hissing/whooshing sound coming from the dash when the aircon is on and think I read somewhere that this could be due to the refrigerant gas level being low? The car has rear aircon too and both systems work, just concerned that this is too noisy and could hint at a problem, off to France soon and don't want it to conk out during the trip.
Our Disco has a weap from the pipe which runs from the condensor under the battey part no BTR 7230. Several peeps report failures on these pipes, Mines gone right on the 90 degree bend. I managed to split a hose and clamp on with some gunk which has slowed the weap down but now our Disco demonstrates the same hiss under the dash sounds like it's near my left Knee area of the dashboard. I've put this down to the refrigerant being low too. Ours has managed to last two years which given the leak is a mere miricle. Landrover want £87 for the pipe... it's about 12 inches long.... Landrover will be wanting for a very long time.
Go for it a re-gas is =A3100... Mine made strange wheezy gurgly noises f= rom the dash area when it wasn't working. Not normally audible over engine and road noise but very noticeable on switch off, with the climate control on and it cooling rather than warming.
Wow. My neighbour is a heating and refrigerant engineer. He says a bottle of gas is $1.50 ( he is American ). He re-gassed my system in ten minutes flat for a couple of beers and £10. £100 sounds like a big rip off to me . TonyB
And a Land Rover dealer doing the work, but as this one is under warrant= y who cares. B-)
They also add a dye so leaks are obvious. It is a rip off though I had a= new compressor fitted to a fridge/freezer for less, chap came to the uni= t to do it as well.
Depends on what's done, I had my Audi aircon done for £90 but that wasn't just re-gassing, it was a full service on the aircon system including telling me where the small leak was, the garage could only connect it up to a computer system that ran through a whole sequence of checks and re-pressurised it, they didn't do simple regassing. I had another car regassed for £25 cash on the driveway by a bloke with a pressurised bottle.
Obviously they wont have a clue of what they are doing, but they GUARANTEE to fix your aircon (outlet air 10% colder than when you brought the car in (though how a percentage of temperature is a useful measure is beyong me)) for £45.
Mine is currently working, but I suspect this is a cheap way of diagnosing if it just low gas causing a system not to work, or something more involved.

Incidentally, I had mine done by an "aircon specialist" who had a very clever piece of Bosch kit which sucked the system down, measured the amount of refrigerant and oil removed from the system, held a vacuum for 20 minutes (leak check) then re-gassed with new R134a and oil. £75.
However, not sure the bloke really knew his stuff. Suspect the machine was brighter than he was...
Hmmm, you could really tie them in knots. Go in at 20 deg C and demand that they get outlet air at -10 deg C, because if they are taking 10% of the heat out they need to work in the Kelvin scale...
Our friend with the cross-axled Freelander no doubt has them in his sights already.
