Having spent nearly a year replacing different components on minibus to no avail with different fault code readings leading me up different paths I done some more testing to find some component signal wires had voltage in them so that would lead me to believe Ecu was back feeding so took the plunge and found CARTECH electronics had a plug and play Ecu ready to clone my one to also there is a option to try before you buy fully for a small fee to test if your Ecu is really at fault brilliant idea!! So from start to finish the whole experience was amazing from them sending courier to cloning and sending back was great have taken long to review as can’t believe I have a fully working minibus with no codes and dash lights four weeks later top work people and many thanks
