    Deep breath - you have probably fried the ECU. Sorry, but that's what can happen if you connect jump leads the wrong way round.

    I assume you have charged the battery using trickle charger? It's worth trying just in case you've been lucky, but the system is not very tolerant of reverse polarity.

    If you have fried the ECU then it's a replacement I'm afraid.

          Bad news - but put it down to experience, it's all part of life's rich learning curve.

            "ECUSTOGO" are one of many specialists on V/X ECU"s they offer fully guaranteed units that are PROGRAMMED to your car VIN number so are plug and play with no issues,have a look on their site give them a call very helpfull and informative, they will send the replacement ECU and you return yours to get the full warranty on them when this is recieved by them, so no waiting.

              Not wishing to be a doom monger, but there is also a fair chance that you have 'blown' the rectifier in the alternator.
              If you didn't keep the jump leads on for 'too' long (however long that is) there is a good chance that the rest of the alternator is OK.
              Haynes Manual doesn't give you much help on this subject, but with a bit of care, you can replace the rectifier or diode pack.
              If the alternator charges when you get the engine running, then great - you have got away with it (this time!)
              If you do strip the alternator and you have a multi meter, just remember that the diodes are 'one-way' devices, so should only pass a current in one direction. If they wont pass a current at all OR they pass one in BOTH directions, then they have been 'cooked'.
              Regards.

              PS I have just spotted the date, so you have almost certainly sorted it by now.
