    I have a manual 57 plate S3 and over the past week, twice its beeped when turning the engine over.
    I get no faults, lights etc and its intermittent, just a random beep not every time I start the car.

    I have no idea what it could be, weather isn't freezing so can't be a warning for that? Only thing I can think is I'm liftingi he clutch a bit early before Its fully started? I have no idea.

    Any suggestions? I don't have any access to VCDS/VAGCOM to run any scans just wondered if anyone knew any possible things to check.

    Both my A3's have done that on random occassions. I've scanned with VCDS and all's clear, so I think it must be something to do with the timing of when I turn the key. It's almost like it's about to show something on the DIS and then you turn the key and it gets confused.

    Even my A3 courtesy car did this once now I think of it.

    Someone suggested previously that it might be something to do with the battery getting low, but after my old A3 was parked for 3 weeks it didn't do it when I first started it so I'm not sure if it's that to be honest.

    On start up my car beeps sometimes and displays an ESP Errorfor a second or two on the DIS.
    I asked the dealer about this and they said there was anAudi document stating that it is a known “feature” of the car and just ignore it.

    I'm only guessing, but it sounds like the start up is interrupting some sort of self diagnosis the ESP is performing at the time.

    Could well be, the ESP light is showing on the dials during start up, but then again I believe it does regardless?
    I'll have a play over the next few days and try and diagnose if it's due to a start up time, i.e rushing the procedure or turning the ignition, pausing then starting.

    Yeah I have RNS-E with bluetooth and the handsfree phone cradle bolted on the dash which is just a big eye-sore.
    But its not that "bong" which you get when the phone connects, it's just a single clear beep.
