Hello everyone,

I own a Audi A4 1.9 TDI BRB engine code, and have been dealing for a while now with boost pressure leaks, i suspected that the turbo had a problem since it was modified to fit a 131hp CHRA and was repaired 4 or 5 times untill now.

I ended up in buing a used GT1749VA took it apart and ordered a brand new CHRA from Melett so i would have a "brand new" turbo.

I mounted the turbo on the car but i still have problems, it will not pull from low revs only above 2100-2200 rpm, and from the logs i made it seems that it never manages to reach the requested pressure.

I have checked all of the hoses and they all seem to be ok, took the intercooler of the car and it seems to be in good shape.

At this point i dont know what else i can check to find/fix the problem.

I uploaded the log here

If you have any ideas i am willing to try anything. Thank you
