Hi guy's
This is my 1st thread and a bit embarrassing at that ,but the best thing is it was my brothers fault
I lent him my cooper s 55 plate for a few weeks while he was looking for a new car ,
He returned it to me today to tell me that he left the lights on and the battery went flat ,so he took it off and charged it over night to bring it back to me today, now here is the problem
When he put the battery back in the car he put the red live wire to the neg (black side of the battery and the black wire to the pos side + and didn't realise it for a few seconds before he looked at it again to see he looked at one of the top up plugs had a cross on it
Now when you turn the ignition on and start the engine all the dash light's stay on i.e air bag engine fault light oil every thing
Is there a way of reseting the ECU or is this a bmw thing and does anyone have any ideas if there could be any damage caused by this
it all starts OK and seems to run OK ,,,Thanks guy's and a bit of info would be good
