2014 Monte Carlo 1.2 Tsi

Hoping someone can give me some pointers before i take the car to a garage and get ripped off.

Bought a 2014 Monte Carlo 1.2 TSI last August to use as a run about when in Suffolk, just before i bought it the owner had the Knock sensor replaced. While driving the other day it suddenly wouldn't accelerate or pull up slight inclines. I carried out a scan and found the following.
