A4 dtc p0299 Insufficient boost pressure


Good morning, I have a 2014 A4 ( With CNH engine kw 140 TARGA FP396HC ) that goes into recovery under acceleration, the DTCs that appear are P2279 intake air system leak and P0299 insufficient boost pressure.

all tubes and fittings have been checked, the membrane of the Wasgate capsule is intact.

do you have any tips for diagnosis?
