Almost sure there was a software update that had to be carried out when exhaust temperature sensor was replaced .If you scanned it with Tech 2/3 or similar you should get the same codes and then you need to work your way through and rectify codes

Had it to vauxhall and theyve said theres no update. First time it happened fixed all the codes and the issues, then it went again with different codes.

Had similar problems with a different car / make that took a while to find and it was caused by a partially plugged cat / exhaust
