Did record some stuff with alfa, tho I'm not sure it saved everything
I did accelerate and wait 30s 3 times, and yes EGR gets back to 0 after 30 sec
Then I drove back home, with some speed bumper on the road (dunno how you call this things)

Not sure you'll be able to use it on computer, raw data but you can put it here \Phone\Android\data\com.android.AlfaOBD\files\logs
Also looking at logs, found this
Target EGR position: -0,35 mm
EGR measured position: 0,00 mm
Last learn of DC EGR engine offset: 0,00 mm
So there is an offset possible ? maybe the -0.4 is an impossible value but configured this way to be sure the EGR is totally closed ?
So after cleaning EGR few days later engine light came back with
Error code: P0409
Exhaust Gas Recirculation (EGR) position sensor
Error intermittent
Error code: P2620 (never had this one before, hope I didn't break it when I first removed this part, cleared fault and didn't came back yet)
Motorized throttle (feedback)
No signal
Error intermittent
Error counter: 35
Error code: P010F
Air mass/air flow meter incongruence
Above top limit
Error present
So, the throttle one only came once when I checked, P010F is almost always there, and EGR appears sometime.
Slow mod still happen when lowering gear (5 to 4 I believe, tho I only notice it after I want to speed up, coz it doesn't give any warning or light)
