P1030 Audi - is this the lambda sensor before the cat?

Question

Got an audi a3 1.8t and i've only just noticed my engine management light was not on, so i had it read because i notice my fuel consumtion was kinda high. 3 codes came up, P0010 which i think is my camshaft sensor, P0030 from what i've been told it my lambda sensor before the cat and 0035 not sure about this one, is this the lambda sensor after the cat?

So after alot of searching and jargon busting i think i need 2 lambda sensors 1 before the cat and 1 after the cat and a camshaft sensor. Would that be right is my question or is there something i'm missing?

Answer 1

P0010 Camshaft position actuator circuit Bank 1

P0030 Heated H02S heater control circuit Bank 1 Sensor 1

P0035 Turbo charger bypass control circit high

Only deal with P0010 , this is for the camshaft position  actuator , with this code condition it will affect the perfromance of the 02 sensor ,

 P0010 is for the camshaft position actuator. This code repesent a open circuit or a disconnection of the sensor either external at the harness or internally, and worste case the ECM .
