Hi, last month I had suddenly had the motor stopping and next day running only 5 cylinders.
I took a Diag : saw it was a bad injector and changed it but didn't see the lambda probe problem (no dashboard light and car running as before).

Well this week I did it BUT still having a particular problem, when I push hard (160-180 km/h) the engine stops suddenly and throws these codes :

Must say that despite the 4530 error running from the beginning I don't see nothing different about power except the suddent shutdown where I need to full stop in parking gear to restart from the first crank like if nothing happened before.
Opened the DDE Box, nothing suspicious in, the internal Box is dry, without dust.
Some insight ?? Thanks.
