Ok I’m happy to let you know that after cleaning the EGR valve and the MAF sensor (I used WD-40 for the EGR valve because the shop near my town didn’t have anything else and alcohol for the MAF) my car has significantly improved in power and it seems it doesn’t have huge problems anymore. I think there is still something that I could do but i will have to check again with the OBD as the light is still ON but it could just be because I still haven’t reset it after the cleaning. I can now clearly hear the turbo spooling at 2k and once i reach near 3k it starts pulling like a beast compared to what it was doing before. I think the WD-40 that I sprayed in the valve and all over the hoses that connect it to the engine melted (don’t know if this is the right word but bear with me) the soot away and I am happy with the results. Thank you so much for the help guys. 

Well done for reporting back, wish more posters were like you!
