Hello
I made a coolant flush following the instructions from ISTA on my F20 and after, I have an error code on ISTA :

S 0797 EGR has to be checked! Leakage suspected.

The EGR has already been replaced and at first glance it doesn’t seems to leak any coolant. The coolant level didn’t drop and I dont have white smokes

Anyone can tell me how to fix S codes in ISTA ?

there's nothing to fix, an S code is generated by ista and is not a fault read from the vehicle.

i dont think you are understanding. there is nothing to remove. S Codes are information generated by ISTA for the technician, they dont come from the vehicle and aren't stored on the vehicle. there was a recall related to this a while ago, possibly the S code is generated because of that. maybe you are using old offline ista version and not current, licensed online version and it does not have the latest updated info. I don't really know, but regardless it isn't important.

Yeah I got it, I can just ignored it BUT what I mean is I already used ISTA on this car in the past and I never had this code before, it came just after doing my coolant flush so it was bit scary to see. Anyway the EGR Cooler was already replaced on this car with the recall action
