    New S3 owner help needed

    Hi, I bought one S3 from 08/2000 with 155.000 km the car doesn't have fault codes, in the engine module, but I don't feel the power that I was expecting?

    What could it be?

    It smells to much to the gasoline outside the car, does anyone knows what could it be?

    I have one fault code in the AC, and it doesn't work:

    Address 08 -------------------------------------------------------
    Controller: 8L0 820 043 M
    Component: A3 KLIMAVOLLAUTOMAT_D77
    Coding: 03140
    Shop #: WSC 06435
    1 Fault Found:
    00792 - A/C Pressure Switch (F129)
    31-00 - Open or Short to Ground

    If you have a strong smell of gasoline outside the car then the fuel filter might need changing. It's under the drivers side of the car.

    If you are down on power try investigating the mass air flow sensor first. These can get worse without showing any errors.

    With regards to the AC fault code, this is what the cause could be:

    00792 - A/C Pressure Switch (F129)

    Possible Symptoms

    • A/C System not working
    Possible Causes

    • A/C System Malfunctions
      • Over or insufficiently charged
      • Refrigerant System blockage
      • Insufficient Air Flow to Condensor and/or Engine Radiator
    • Wiring to/from A/C Pressure Switch (F129) faulty
    • A/C Pressure Switch (F129) faulty
    Possible Solutions

    • Check A/C System for Malfunctions
    • Check Wiring to/from A/C Pressure Switch (F129)
    • Check A/C Pressure Switch (F129)

    Hope this helps.

    On a car of that age I'd be changing plugs, filters, maf, coilpacks anyway just for piece of mind. Don't be surprised if the turbo is tired too.

    The idea is to change that and other stuff in the car, but now I don't have time to do it...

    I think that the car it's running good today, it's a lot more cooler than last week, and now I'm using 98


    How do I do to program the door close at 15km/h?

    You need to download a little program called "basecode" and that will work out the code you need to enter into VCDS to code it.
