There's an S3 just gone in car parts for breaking if it helps.  Fingers crossed for you mate, always silly mistakes that cost

Got auto spark arriving at 2pm to diagnose prob. How does he narrow it down to being 100% ecu problem? Is there a test? Thanks lads, Stevie.

Are you sure you've fried the ecu, that noise is the same as low battery voltage failed start. If you have rapidly discharged the battery then it could be fubar and it needs 12v for the various computers to operate so an 11v battery wont turn the car over and jump start wont help.

Have you put a new battery on?  If VCDs or similar cannot communicate with car with a fully charged (known good) battery you may well be right about the ecu  :sad1:

No i am not sure. I have not rapidly discharged the battery recently. I have tried two batteries in the car. I phoned my audi garage told them the story, straight away they said ecu. Stevie.

If it helps, we can clone the ME9 ecu, this means you can buy a second hand ME9 from another TFSi and we can copy all of your cars memory dumps onto it.

Will gladly do it at postage costs plus a few beer tokens  :happy2:

By connecting the wrong terminals you would have put the positive terminal to the earth and the battery would have discharged, you might well have an issue with the ecu but if you get the clicking sound and the cluster dash picture red screen starts going dark and funny then you have an under voltage battery.  I've had this on several occasions due to a battery drain issue so worth getting a volt meter on it to check the voltage.

Still not 100% sure it's the ecu yet. Had the coils out of the car yesterday with the plugs plugged in, cranked it over to watch the spark and the plug sparked everywhere apart for the place it's meant to?? So when I thought it wasn't sparking it is actually. New plugs arrive tomorrow then after that I am kind of stuck. Thank you very much pdt that is very very kind of you it might still come to that, see what price west comes back with on the s3 ecu. Not giving up. Appreciate all the help.  :happy2: Stevie.

Remember to hold the body of the plug (threaded section) against an earth while testing the spark)
