It's not like on EDC15C2!
Some of the info I got already is to find the egr hysteresis maps and lower the temperature of the EGR working state.
On SID801A EGR doesn't work when the temperature is bellow 0 degree cels.
I tried to find out the right maps, but with no luck till now.
Some of the guys like "zotto" knows the solution, but it's not going to make it public. I understand that, because I think they found that solution hard with alot of work and investigation. So that's all for now. I'm still searching for public solution, and hope someday, someone will reveal the secret :)

There's a solution for SID803 which is probably close to SID801A, but I can't figure it out yet.

I also think that it will close. and I believe that together we will come out to shut down the EGR SID801. I plan to try to make one file. then pinning him here that you say it, only now I do not have a car to test. All I have are EDC15C2 and EDC16
