Thanks in advance.

EGR off file for you. Disconnect the EGR valve!
P1612 isn't touched...

THE PROBLEM
After writing IAW ECU you sometimes have P1612 DTC but sometimes not...

THE REASON
Kess changes ECU codding after write. When you have car without AC all is fine and you have no DTC after write. But when you have car with AC you get P1612 DTC after write because codding is change for no AC.

THE SOLUTION
Use VCDS and change your codding back to stock.
