    Hi Guys,

    Recently I looked into getting my Air con re - gassed becasue my car is over 3 years old now. Apparently you are supposed to get re - gassed every 2 - 3 years and I noticed my air con was not that cold. I rang my local Audi garage and a few independants and the average was about £65 plus! Then I found this on the Interweb http://www.id-usa.com/product.asp?CID=27&PID=92 They sell these in Halfords for £39 I thought it worth a try so promptly bought one. I returned home and followed the instructions and it was a doddle. On the built in gauge it told me I needed to add gas so I did until the needle went onto the blue mark which meant 'OK'. What a difference it made! Lovely Ice cold air now comes out of the vents instead of cool air. I must have used about 1/5th of the can so it means I have plenty more to use again or do a mates as a favour. If you reckon your air con needs a re gas and you don't want to pay a 'specialist' to do it then these are well worth a try.

    Looks good. Which Audi model do you have, and where does it connect up?

    A4 b6, There are 2 pipes below the drivers side windscreen wiper, just before where the pollen filer is, one thin and one thicker. Both should have either Black or yellow caps on. Just unscrew the thicker pipe cap and pop this thing on. It will give you a readout of how much gas is in at the moment, then just top up as required. Easy Peasy! Im going to use the Comma air con cleaner this afternoon too, its supposed to get rid of bacteria etc and make the car smell new again.

    I've used the Comma cleaner a few times before, and it's great. Thanks for the heads-up on the re-gas, I'll give that a go in due course.

    John, I've got a B6 model as well (2003 2.4V6), and I went looking for the pipes this evening,. I found what I think is them, in front of the forward bulkhead, near to the engine air filter housing. I took these pics:

    And here's a close-up

    Are these what you were referring to? If they are, I think you might have been confusing the air filter with the pollen filter. The pollen filter is tucked up under the rear bulkhead, on the passenger side.

    If these are the right ones, I'm guessing I should unscrew the ribbed cap, yes?

    I've spent some time browsing that US website, and there is some great info about A/C on it. I've confirmed that the ribbed cap is the right one, as it for the "low-side" port.

    I also discovered that the product that costs £39 in Halfords over here is $22 over there!

    I've just used this, and totally endorse what John said. Mine was just teetering on the edge between the green & blue sectors on the gauge, so I added enough gas to take it to the upper edge of the blue sector. It took about five minutes.

    Dead simple to use. I just wish the price over here was more in line with the USA, where it costs the equivalent of about £13!

    No idea, but it might depend which A3 you have. On my old B5 A4, the ports were hard up on the rear bulkhead. but on the B6, they're much more accessible, as per the pics. It might be the case with the older & newer A3s as well.

    Your best bet is just to open up the bonnet & look for them. After all, you know what they look like now, don't you?

    I have been using these for 5 years + in various guises. There are various suppliers in the uk for these. the last ones i bought was in the uk was from

    http://www.car-air-conditioning-supplies.com/carshop/home.php?js=y

    However the gas is 8.99 a can on its own. the shipping is £7.95

    Worth ensuring you get 1 can with oil in

    I have also used R12 to 124a converstion kits which worked fine on my old 1990 honda accord.

    I generally bought mine from Walmarts in the states where three cans plus connectors and hose/gauge are about $28 dollars and cans alone are $4.00 I have done three cars.

    These are larger cans than are being flogged by halfords. The halfords 1 is extremely expensive for what you get.

    Inter dynamics is the main biggy in the US dont know if they sell over here.

    http://www.id-usa.com/

    They do single cylinders through to varios kits which include everything even for older cars.

    one word of warning Be careful not to overcharge the system and keep the can upright.

    Occasionally get the airconditioning serviced as this removes any internal moisture from the system.

    at £65 quid now is good 5 years ago it would cost you £150 for halfords to do it and that was cheap then elsewhere was over £200.

    Goods luck
