Technical Slow mod ?

Ok so i did some tests. My turbo is overload pressure or sensor in manifold is wrong becouse mbar is top high but position of turbo is ok. I did egr test too and i think its fine. But if anybody can tell me that my turbo is going to change or maybe sensor is wrong. Turbo is sometimes loud and make somethink like blow off but i have pipercross intake. Put results in csv evening.

GF left early, couldn't do the things, I'll do next weekend or maybe even friday, xept I find some free android app
 
Evo63 you can download torque app or best alfaobd free app (15min test after connected to ECU everytime you start the app )
 
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)
 
So, reset codes and observ that is shows again. You can make photo from alfaobd with turbo position and turbo boost valve. My turbo boost valve shows 61% and 0,62 mm turbo. Curious what yours?
 
Bought a new EGR, but joint wasn't with it so I added one on the order, but it's not one that can do...

I don't really know where to get one that fits correctly or if there should be one in the first place

diameter 41mm en 80mm between screw hole, tho a simple 41 circle joint could do
 
After I finally had all needed to replace the EGR I started but the screw got ****ed... So I didn't proceed as I didn't have any backup plan

Finally got someone to help me and replace it

There was once again some liquid going out from it

Probably coolant ?

I was told there is some kind or cooling system to lower gaz temp before recycling them, and the leak should be coming from it
Something like this ?
thumb

Price 144€

Got no idea yet if slow mod of P010F error still come up, will have to check on this in coming weeks

If the car run smooth, is it bad to leave it this way ? Must I replace that unit ? Saw some pretty high price with mounting done, I guess a lot needs to be dismounted to replace it
