Guys, I’m hoping you can help.I have had P201,202,203,204 and P245 messages and typical ECU symptoms of not starting in hot weather, excess fuel, and so I replaced the ECU with a used one and flashed the original bin files to the new ECU using trioniccanflasher according to all the instructions. Initially my Saab ran well without fault codes for a couple of days but then started throwing the same codes, though the car still runs perfectly - a fortnight after replacement. The replacement ECU was sent tested and verified, but could it still be faulty or is there another problem. I did use a 2007 ECU but downdated the MCP files to suit my 2003 model. Would appreciate any advice. Thanks
