first just have to say i dint expect a reply tbh

secondly many thanks for the input/advise ,as tbh i know buggar all regards this type of ecu/bsi other then there a bloody nightmare, i have found a very very small part which has been melted of the board , which brings me to think its more of what you say a ecu fault,
question is ive found a few ecus but theres a few numbers differnert , but complete set up would be avaible ? ie ecu,bsi,key chip,transponder ?
but some say i need the clocks as well other say not ,which im not totaly tbh, i can only think of 3 options replace all the set up and see if it runs, send ecu off for a possible repair or try locate one with identical numbers(hard work) oh or fire the twat lol
