Hi All on Saturday just gone replaced rear wheel bearing also cleaned off all discs and pads after inspection.Car drives lovely now no bearing noise but day after 8 miles later I get an engine management light borrowed a code reader from a friend and checked it shows TDC06 upon looking about it relates to Exhaust Valve Short to Ground/Open Circuit does anyone have any input to what to check repair etc as it's not all clear on posts I've read.The car drives but lacking bit of power and can't hear turbo as purgey as before ? Many thanks 

Does that not say that there are 6 DTC's, rather than give a actual code? 

^ That was my first thought too.

What happens if you press enter again when it's showing that?

Doh I'm a noob at this I reset it earlier once the light flags again I will rescan and post my findings thx

Light flagged put code reader it gives fault code of 16785 which relate to egr valve or connecter is it much of a job to clean or replace ? 2.0 TDI PD
