    Air Con Lost

    Hi Chaps,
    This was perhaps the warmest day here in England this year and my car chose today to cease breathing cool air for my comfort.

    I'd like to attach an autoscan and a adaptation map and measurement block map each for channel 9. I could not see a security code to enable me to do the same for channel 8.

    Unfortunately I seem not to be able to attach files. Is that because I'm not yet a heavy enough user?

    In Channel 8 the fault code are 00457 and 00256 and 00256 also appears in Channel 9.

    Is it just the temp sensor on top of the a/c rad or do you reckon there is something else wrong?

    Thanks in anticipation of your help.

    You don't attach them as files, you post them inline between CODE and /CODE (in square brackets) tags.

    Hello,

    - Thanks for posting the Auto-Scan, the G395 sensor can be a common cause of 'no AC' failure on these vehicles.
    If you look at the A/C condenser, the G395 should be on the outlet side line. I would suggest to disconnect the electrical connection and see if there is any evidence of refrigerant oil leaking, a common side effect when these fail.

    We suggest to consult with the Official Factory Repair Information for component locations and proper repair procedures.

    - You can use VCDS to view the G395 pressure in the Measuring Value Block group 1, field (4). This sensor should read about 1-bar of atmospheric pressure at sea level when NOT connected to the refrigerant line, so if there was no refrigerant in the system, you should at least see a reading of 1-bar. With a properly charged AC system, static system pressure could be 4 to 8 bar depending on temperature and the amount of charge in the system.

    If you end up replacing a defective G395, be sure to clear all the fault codes.

    ref: 00256 - A/C Pressure/Temperature Sensor (G395)
    008 - Implausible Signal

    Also have a look at this Ross-Tech forum post we have: Tis the HVAC Season


    Hope this helps and be careful!!! AC systems and refrigerant dangerous if not properly understood and worked on with safety in mind!

    Thanks Dr P.
    I have replaced one of these on my old B6 A4 and it was pretty simple, but I appreciate the warning and your guidance on the pressure readings I should expect.
