    I've got an 09 Ibiza SE SC 1.4 with climate and the air con compressor is noisy. Not to the extent it is obviously broken but you can hear it whining at idle and when you rev the engine. Once you get above 30mph you can't hear it due to road noise etc but I still think there's a problem with it, a view not shared by the dealer,or indeed Seat, who are aware of noisy compressors but apparently can't do anything about it. I think its a bearing or similar going (thank goodness for warranties) but until it lkets go Seat/Dealer won't do anything. Anyone else ahd a similar problem?

    Yes, it was the expansion valve apparently. I had to take it to another dealer for a second opinion after I got in contact with Seat again and the tech came out and straight away said it was noisy. I don't know how much it cost as it was under warranty. Only problem is the noise is back albiet quieter....

    Anybody got idea where the expansion valve is for this system and if it can be tested in any way??Local aircon specialist has never heard this sound but suggested a re-gas.Did think could possibly be a vibration in compressor etc which is being made louder through the condenser.On starting there is some faint rattling from behind dash but only when acon is on-then when idle or driving slowly car almost sounds like it has a straight cut gear box as whine builds with engine revs.Again as other post with more speed /road noise etc this is not as audible .When you lift bonnet there is no noticeable noise from compressor or assoc acon pipes although maybe a small vibration on pipe itself although this does not get worse with revs?.

    OK expansion valve is on os on aircon pipe just in front of susp turret-bolted onto pipe and has electrical connector.
    Priced at around 50 from dealer seems like a bet before compressor.Had a little gas seemed to blow through air vents today though so may be a separate issue?
    cant see how the exp vale would stop whining of aircon when revving engine at low speeds though-anybody any ideas?
    Dealer admitted these do give trouble as well as compressors but the compressor is an even bigger issue on Leon they have told me.

    I know this was over a year ago, but did you ever solve this Mike? I have what sounds like the exact same problem with my Ibiza. If you tried replacing the valve, please do share I'd really appreciate it.

    Thanks in advance =]

    when you have your ac systems topped up by professionals they add a certain amount of oil in to the system too there will be a metal plate under the bonnet that tells you how much oil should be added when the systems are re-charged. if you have your ac topped up with the throw away cant you are not replacing the oil in the system if your compressor is making a noise i would recomend you have a full recovery done then a top up with new gas and oil replacement.
