Hi guys i'm a new member who needs you guys to help me

Recently bought a 2002 octavia vrs 130k after wanting one since the police used them.

Getting the fault code p1297 pressure drop between turbo and throttle . Also when I drive the car with traction on , it sort of misfires or something and the traction light flashes . But if I turn the traction off it seems fine also my boost guage needle is shaky at times too :( hope you guys can help
