DPF Regen question

[SectorOMEGA]

Hello, everyone. I know there are a lot of threads out here about this so excuse me for adding one more Last night I was driving home from night shift and I got the Service vehicle soon msg on the screen(Astra J sports tourer 2011 2.0CDTI) Didnt pay attention as it was late and was tired. Today I plug it my laptop and saw the P2458-57 error. DPF regen uncompleted or something like that. No lights on the dash. I assumed that taking it out for ride will regen it, but when I jumped on the highway, I noticed the limp mode. Returned back to my parking and decided to force regen it via opcom clone. It started to rev up the engine first at 2k than in a minute it rev it up to 3500 and stood there. At first no smoke went out then for about two minutes white smoke started to go out the exhaust. Left it like this and then the smoke stopped. I have cleared the error and took it for ride. The limp mode has gone and the error didnt pop out again. I have never seen the rear demist light to came on. Also my op com is not showing any progress of the cleaning and the other stuff. Have I done something wrong? And is the LED added to the mirror plug actually working? Thank you in advance for the help
