DIY A/C regas. what do we think?

[S2central.net]

On the part numbers - there was thread started by MartynF on this ages and ages ago - he found some mistakes on the family album.

I have no idea why Audi thought it wise to put the LP port where they did... Tis a really awkward place alright. You have three choices -

1 - work with some wacky / special hose that can access the LP port in the cabin
2 - make up a hose adapter for the LP port on the compressor (PITA as the undertray has to come off)
3 - use the HP port instead - but NEVER recharge from a low pressure device with the engine running

Please can someone tell us the part numbers so I can get new hoses on mine, I have a leak apparently, the lads did a vacum test from the high port, and smokey stuff came out the Air Con machine apparently telling us I had a leak!

The Technician did not understand why there would be a port in the footwell (Under Carpet?) and he did not seem to have a correct fitting on the AC Compressor, so he ust used the High port under the radiator Cover on the nearside front of the car.

(Was this ther right way to do it?)

i will check with the local garage and see what the whole deal will cost. I have been quoted 150GBP to have that hose mended and regas, but i think most of my hoses are on the verge of destruction so dismantling the car 2=3 times to change one hose at a time is not a good option. It will either be, do it now all at once, or leave it until i get back home(ie 2-3 years), as living in the UK is not excactly the hottest country in europe anyway.esp in the north east
i bet the car would have to stay in the garage for 2-3 days to get all hoses stripped, redone and refit.

thanks for the answers guys.

Pirtek can make you up the hoses for reasoonable money using your current connectors

[S2central.net]

From what I know - the drier should always be replaced in such a situation - it is filled with dessicant to remove moisture from the refridgerant. If you have had a broken hose then the dessicant will be saturated with moisture from the air - as well as you losing all the gas.

For that price from ECP or GSF - go for it - but the hose will be expensive I am sure.

[A80Avant]

so it seems the drier is cheap. But i thought that these pipes can be redone by replacing the hoses on the ends of the metal parts. It should be cheaper than getting them from the stealers

[s2driveruk]

hope you have more luck with an ABY than I did trying to source those pipes for the 3B, was looking for months before a couple of guys from here saved me

I paid £27 for the drier from GSF the other week...

[A80Avant]

ah thats nice...

Dryer is £33 from Euro Car Parts

second damn, each one of these pipes costs more than 100GBP!!!! + 100 for the drier!!! this sucks. I hope i can have these pipes made rather than having to buy them from audi...

[A80Avant]

Damn, apperantly i have a leak from the hose that goes from the dryer through the wheel arch towards the ac unit in the cabin. The metal hose was touching the spring and it perished it!

its either no AC for me in the UK (not really needed) or organise a full redo on the hoses. The guy who came told me as well that the dryers tend to get their screws seized over the years and i may end up needing a new dryer as well... grrrr

then again i knew this day would come at some point... A/C has never been touched on this car for repairs so...

does anyone know where exactly is the correct place to fill an empty system,
Port on compressor
Port in passenger footwell
Port next to heat exchanger

Depends on what you're using to refill.

If it's a top-up can then it'll come with a low side connector which will mean you have to use the footwell port or the compressor port (if the port on your compressor is compatible). To use a top-can on the high side port on the condensor radiator you'll need a high to low adaptor and must NOT run the engine whatever it says on the can. (The pressure on the high side if you're running the system will make the can explode)

If its a full garage A/C recharge system, it would normally connect to both the high and low side ports but many can be used on the high side port only - which is the easy one to get onto.

people say it should be the low pressure port and that is on the compressor. However mine has always been gassed through the high pressure side(at the condenser) without issues
