I may well be corrected by someone with better knowledge on this but..... I thought the ECU coded to the UCH, you can code a new engine ECU to the UCH, but a used ECU will need to be virginised before you can use a 2nd hand unit. Are you sure its not a UCH (immobilsor) fault? We have replaced several UCH boards on clios. The flashing red light means the engine is immobilised. Sometimes I have been able to leave the UCH disconnected for 10 minutes or so and then it's been ok. Keep us updated Nick |
