Zafira B Engine change question

[z786]

Hi, have replaced a zafira B engine witha vectra C

engines look identical apart from an air reservoir.

both engines are z19dth but i assume ecu will have different sw versions.

car drives fine until you stop at junction and then goes into limp mode, no dtc, no warning lights, seems like a vacuum fault as in turbo actuator stops working

any ideas plz

thanks
