I have 2014 passat tsi 1.8t, when i drive in the highway my EPC light goes on and i lose power, and if i take it to the dealer they cant fined any code, and i started noticing that the engine burning oil more than the usual, so i got the OBD2 code reader and i waited till the EPC light come, i found these codes (15082 - Cylinder 1 knock control (limit reached) 15083 - Cylinder 2 knock control (limit reached) 15084 - Cylinder 3 knock control (limit reached) 15357 - Torque restriction due to fuel pressure) so i don't where to start?
