    I have a A3 2.0TDI sportback, the stop and start hasn't worked since prior to Xmas, I presumed this was due to the weather change, but after searching net, and reading Audi book, stop start should work unless temp is below 4 degrees.

    I have followed book and tips on net, but each time I stop at a junction and release the clutch, engine stays running, display on dash that stop start not activated (same display as if air con was on), what also baffles me even more, if I where to stall, if I press clutch in, engine starts.

    Can anyone give me any tips on how to test please?

    Many thanks

    There are a few conditions that effect the start stop,

    Drivers seatbelt - make sure it is in nice and tight.
    Internal temp - if you car does not think it can maintain it it will keep the engine going
    Battery level - if this is borderline it will also keep the car running
    Outside temp is to lo it keeps it running.

    All the start stops I've seen stopped working due to the battery. So I'm 99% this will be all your fixs. Albeit you've met the start/stop criteria above ^^

    Thare are a number ofvthings that can affect the start stop system but the number one issus is low battery amps/volts some of the others are the internal temp setting, the drivers seat belt, AC on and I am sure there are a few more

    'Varta' is the OEM battery from Audi, you will need 70Ah and 680A cold cranking amps, I'd recommend the start stop version which has 760A for CCA. The part number is below.

    Should be fine as it's within there Ah safe range, just make sure it's the right size for your battery bracket.
