Need Help - VCDS Codes

[moleskn1]

Hey Guys,I scanned my car just now after getting my engline management light on and I am getting these 2 errors.
Any help much appreciated.

Is it just a case of replacing these parts or are there ways to diagnose and fix them?

Have you checked the codes on the ross tech site ?

are you also cleared DCTs and re-scanned them? could be old codes or just triggered cause of some maintenance or work on car.

Hi mate, Ye i have cleared them they keep coming back up

Have you checked the codes on the ross tech site ?

Did have a quick look but it dosent exaclty say what it is, Think i could need a new throttle body!

spray a bit of wd40 - contacts cleaner on pedal then move it in full range few times pushing it to left and back then clean it and dry, clear codes, if coming back - check and clean throttle body.
For lambda, try to change position of it with the one from second bank if problem move to bank 2 change the sensor.
