Darren we are ALL very fortunate to have andrew and yourself help with these issues as i know all to well .We had 2004 E46 330 coupe came from a bmw dealer to us,they had supplied a new ecu and tried to programe it to the car with out success they told him there was something very serious wrong with the wiring/electrics, that is the words they used.A few coversation with andrew the ecu was programmed customer very happy his car was no longer scrap,this took valuable time of andrew,s which he gave with out question. I hope this problem has not put james off,hopefully he will realise how good this forum is,there are people who contribute who a lot of us cannot hold a candle to.regards Mike mcDowell
