Hi i was recently told i needed a new ecu for my seat ibiza 1.6s.Has had a few starting problems and when i took it to the garage the ecu was giving no reading.I got a new ecu and I took the car to a seat dealer to get the new ecu coded.They plugged it into their computer and the new one is also giving no reading.Could there be a loose wire somewhere?Really appreciate some help!!The ecu has cost a fortune,now i am wondering if there was anything wrong with the old one and the seat garage charge a silly amount for labour!!
