I've found an ECU repair shop that will do it for £150, he says he can fix 99% faults that are caused by earthing out. So I'm going to send that off and hopefully he can do it, saves me having to reflash the ECU and get it remapped as well :)
 
hope my fault isnt this :(

caused after a jetwash , but handy to knwo ecus can be repaired mst the time

what genious decided to put the ecus on the leons under the scuttle panel , why not in the dash somewhere ??
